Hydraulic & Morphological Study for Design of Protective Works for Marine-Drive Road Project

Data Collection & Bathymetric Survey using ADCP for Regional Cooperation and

Integration Project (RCIP)

The Marine-drive road project connecting Cox's Bazaar with

Teknaf began in 1993-94; Phase-I of the road from Kalatoli to

Inani (24 km) was completed in 2008. In Phase-II, another 24 km

road extending Inani to Shilkhali is under construction from July

2008 and is scheduled to be completed by 2013. The project has

been taken to facilitate tourism, regional connectivity and

fishing activities. Since commencement of the project, few

locations of the Marine-drive road has been damaged from

wave action of sea as reported by the Bangladesh Army. The

Roads & Highways Department commissioned IWM along with

BUET, DHI and EML to carry out the study to find a cost effective

sustainable solution to the erosion problem.

The main objective of the study is to investigate coastal erosion

processes along the Marine-drive road, review existing

protective measures and devise immediate & long-term

mitigation measures.

Situation in specific locations are extremely severe and subjected to

severe shoreline erosion. Considering existing situation it is urgent

to devise immediate protective measures against shoreline erosion.

The Bangladesh Army successfully used geo-bags as immediate

measure to protect the marine drive road from erosion however, an

authentic design is needed to overcome the present situation.

A Joint Communiqué was signed in 2010 between the

Government of Bangladesh and India in connection with sub-

regional and Trans-Asian Railway (TAR) connectivity with

assistance from ADB. Under the project, the RCIP, Rail

Component, involves design of new or upgraded railway

crossings over number of major rivers. In this regards, hydro-

technical investigations are being undertaken to derive

hydraulic design parameters for rail bridge crossings of major

waterways, establishing river training works and bank

protection requirements.

To support the design works through field investigations,

CANARAIL Consultants Inc. of Canada requested Institute of

Water Modeling (IWM) to undertake and document river

bathymetry, bank line location & topography and flow

characteristics using RTK GPS. The survey was done in the

Modhumati, Arial Khan, Dhaleswari, Buriganga and Gumti River.

Under the program, IWM successfully completed field data

collection activities in August and September, 2013.

IWM carried out comprehensive survey viz. topography,

bathymetry, suspended sediment, bed sample, velocity

profiling & level measurements. IWM also deployed

Workhorse Sentinel ADCP in the sea, use of first ever such

equipment in Bangladesh to collect wave height

measurements.

IWM also carried out analysis on historical bank line changes

using satellite images of 1974, 1980, 1989, 2000 and 2012 to

indentify vulnerable locations and shifting characteristics of

shoreline in Phase-I & Phase-II of the project area.

Monitoring surveys at vulnerable locations were carried out 4

times in 2012 and 2 times in 2013 to analyze & assess

changes in near bank slope in vulnerable areas and erosion-

deposition pattern. Based on these monitoring data IWM

provided an immediate temporary protection design in

consultation with BUET for the vulnerable locations.

The modelling work is continuing in consultation with DHI

experts and selection of proper protective works and design

is being carried out by IWM and BUET in consultation with

experts from DHI and EML. All modelling work and design is

expected to be completed by December 2013.

Hydro-geological Investigations & Groundwater Modelling for the Northern Part

of the Barapukuria Coal Mine Basin Area

Assessment through Mathematical Models of Impact to Surface & Groundwater Resources

due to Climate Change for Pilot Areas in the Coastal Region of Bangladesh

The Barapukuria Coal Mine in Dinajpur district in North-West

Bangladesh is the only underground coal mine in

Bangladesh. The coal deposits is underlain by a thick water

bearing strata (Aquifer; Avg 107 m) . The coal reserve was

discovered by Geological Survey of Bangladesh (GSB) in

1985. The U.K. based firm "MIS Wardell Armstrong" and

China based organization "China National Machinery Import

and Export Corporation (CMC) carried out some feasibility

study in Barapukuria area and confirmed about 390 MMT

reserve of coal in an area of 6.68 sq kms. The quality of

Barapukuria coal is also better compared to imported coals.

This gives Barapukuria coal competitive advantage over

imported coals. Barapukuria coal is also low in ash and

extremely low in Sulphur content which meets international

environmental standards. On completion of supplementary

geological survey and basic design of the mine by CMC and

approval by Petrobangla, physical works of the project

commenced on 1st June 1996.

The present underground mining area covers the central 3 sq

km out of 6.68 sq km reserve area. No coal extraction is

carried out from Northern 2.81 sq km (Reserve 135 MMT

Approx.) area where coal exists in relatively shallow depth.

Presently it was decided to conduct study for selecting

suitable methodology for extraction of coal in the Northern

part of existing mining area. To select suitable methodology

for mining in the said area, a detailed hydro-geological and

groundwater modelling study is being carried out by IWM

under an agreement with Barapukuria Coal Mining Company

Limited (BCMCL) since October 2012.

The main objective of the proposed study is to develop

preliminary mine water management plan to control

movement of surface as well as the groundwater on and off

site, over the production period of the mine life, if "open pit

mining" method is selected. The study also addresses suitable

strategy for mining in fulfilling following specific objectives:

" Surface and groundwater resources assessment in and

around the northern part of coal basin area.

" Assess dewatering requirements & regional impacts to

groundwater level due to dewatering.

" Define problems of irrigation, drinking and industrial water

supply due to mining & suggest remedial measures.

Find out possible remedial measures for groundwater

The study is one of the 3 packages of the BWDB project titled

"Establishment of Monitoring Network and Mathematical Model

Study to Assess Salinity Intrusion in Groundwater in the Coastal

Area of Bangladesh due to Climate Change" funded by the

Climate Change Trust Fund under the Ministry of Environment

and Forests.

The main objective of the study is to assess surface water

resources in significant rivers as well as upazila-wise groundwater

resources for 2 Pilot areas in the coastal region and observe

changes in future due to climate change. Both areas bear different

groundwater use pattern and hydrological characteristics.

Pilot area-1 (PA-1) is about 4867 sq km lying in 15 upazilas of

Southwest Region & Pilot area-2 (PA-2) is about 946 sq km

spreading over 8 upazilas of Eastern Hilly Region.

In order to achieve the study objectives, a modelling study

supported by comprehensive data collection program has

been carried out. Modelling softwares MIKE SHE and MIKE

11 were used to simulate water levels under present and

future hydrological conditions of 2030 and 2050 due to

climate change. Main activities of the field data collection

included water level and salinity observation at 13 locations,

discharge observation at 6 locations and seepage-percolation

sustainability of the area through different option studies.

" To understand and assess rain water drainage and flooding

situation in and around the proposed coal mine area under

different scenarios.

" Analyze quality of coal seam water and mine drainage water.

The study will help in better understanding of the surface and

ground water resources in the project area and their

interaction, dewatering requirements, probable impacts of

dewatering, identification of remedial measures and finally

assist BCMCL authority in deciding the method of coal mining

to be adopted in the area.

Monitoring of Hydraulic & Morphological Conditions of the Jamuna River for Safety

of River Training Works of Bangabandhu Bridge for the Period 2013 to 2017

Figure showing plan form of the Jamuna River

measurement at 23 locations in the 2 Pilot areas.

Assessment of consumptive water demand of water by

consuming sectors such as agriculture, domestic,

industrial, forest and fishery were also done.

Agricultural water demand is significantly higher

compared to other sectoral demands. Agricultural demand

in PA-1 increases from 1743 Mm3 under base condition to

1815 Mm3 and 1860 Mm3 in 2030 and 2050 respectively.

In PA-2 it increases from 304 Mm3 under base condition to

327 Mm3 and 319 Mm3 in 2030 and 2050 respectively.

Availability of surface water resources were assessed at

the upstream and downstream chainage of 4 major rivers,

and were found to have sufficient flows. Surface water

salinity remains below 1.0 ppt in 3 rivers namely Biskhali,

Bureswar and Tetulia. However at downstream of

Baleswar river, salinity becomes more than 1.0 ppt during

dry seasons and reaches to about 6.5 ppt maximum.

Under average hydrological conditions, potential

groundwater recharge in PA -1 varies from 183 mm to

291mm and in PA -2 it varies from 396 mm to 522 mm. In PA

-1, during dry season GW salinity remains below 1.0 ppt only

in a small part of Bamna, Amtali and Kalapara upazilas and in

rest of the area, salinity remains above 1.0 ppt. In the wet

season, the situation noticeably improves. In PA -2, in dry

season 1.0 ppt salinity range spreads over a larger area

extending from the sea side upto the eastern side of the pilot

area following a narrow strip along the middle part of the area.

Under climate change condition, no significant change in

maximum depth to GW table in the pre-monsoon season is

seen. On the other hand, there will be a noticeable increase

in post monsoon recharge under climate change condition

compared to the base case.

Bangabandhu Bridge

West Guide Bund

Bhuapur Hard Point

East Guide Bund

Bangabandhu Bridge is a nationally important

structure in Bangladesh built on the mighty river

Jamuna. An average 13 kms section of the river

discharges 60,000 m3/s which is guided through a

4.8 kms section between 2 Guide Bunds of the

bridge; river responses due to the constriction

needs to be attended intelligently for safety of the

bridge.

The Jamuna is one of the world's great rivers,

ranking the top three in terms of both sediment

& water discharge. The figure on the right shows

constriction at the bridge location;

variable flow and sediment along with

upstream condition plays major role in

governing morphological processes that can

endanger stability of the Guide Bunds and

the bridge. In order to protect and face

adversities, every year before onset of the

monsoon, the Bangladesh Bridge Authority (BBA)

adopts preparatory works to update its

monitoring plan with forecast on critical hydraulic

& morphological conditions in the vicinity of

bridge location and specifically for river training

works (RTW) under the framework of

preparedness program. The RTWs consists of two

Guide Bunds and Bhuapur Hard Point.

Mathematical Modeling Study of Proposed Railway Bridge on the Rupsha River in

connection with Khulna-Mongla Port Rail Line Project.

Development Design Consultants (DDC) Ltd. is providing technical

support to Bangladesh Railway (BR) for the project. Institute of

Water Modelling (IWM) has been engaged by DDC to carry out a

hydro-morphological study of the Rupsha River in connection with

the proposed construction work in the pre-construction phase.

IWM will investigate the suitability of the proposed bridge site,

predict anticipated scour at the bridge piers, hydraulic design

variables for the bridge and safety measures required in considering

erosion of the banks using mathematical modelling tools.

Forecast of morphological behaviour in the vicinity of

the bridge area that needs to be addressed includes

maximum flow thrust, bank erosion at the immediate

upstream & downstream of Guide Bunds, probable

scour and period of occurrence.

BBA awarded IWM with the monitoring project in July 2013

after IWM came out successful in a competitive

bidding for the project. The objective of monitoring is

to support BBA in devising its monitoring plan for

requisite preparedness before onset of monsoons, for

5 years, in safe operation and maintenance of

associated RTW of the bridge using state-of-the-art

mathematical modelling and survey technologies.

Approach of the study is to forecast probable hydro-

morphological situation of the Jamuna for

preparedness of safety of RTWs of the bridge, and

devise monitoring programs to make the

preparedness effective and timely. The entire gamut

of the study, as conceived, has been shown in the

flow diagram on the right.

At the End of Five Years

The Southwest Region of Bangladesh is

criss-crossed by numerous rivers, which

ultimately fall into the Bay of Bengal. The

Khulna city, a divisional headquarter is on

right bank of the Rupsha River. Major

business of the region is centred on the city.

The downstream reach of Rupsha River is

named as the Pussur River on which

Bangladesh's second largest sea-port is

located at Mongla. Khulna city has road

communication network with Mongla port

though there is no railway tracks between

the two important cities. Importance of

Mongla port increases by each day as the

other sea port located at Chittagong has

become overloaded with increased

shipping activities of the country.

Mongla port has high potential in becoming

a regional port since Nepal and Bhutan

could easily use its facility rather than the

Haldia port at Calcutta, which they use

currently. For this purpose a railway

communication is essential between Khulna and Mongla

ports to facilitate and make the port more effective.

The Bangladesh Government has decided to link Khulna city

and Mongla port with rail tracks, which is to be

implemented in the next few years. Bangladesh Railway (BR)

took up a project to establish new railway tracks and also

renovate the existing rail tracks. Under the project, crossing

of the Rupsha River will be facilitated with a railway bridge

near the existing road bridge called Khan Jahan Ali Bridge.

Consultation with Narayanganj City Corpn Town Planner on urban drainage adaptation options.

Climate Change Impact on Urban Drainage System and Adaptation Measures

It is now commonly accepted that climate change is

occurring. For Bangladesh, this means increased variability in

rainfall in terms of amount and also frequency (CCC 2006).

There is growing evidence that this is already happening with

extreme monsoon events (e.g. in Dhaka the heavy rainfall

events that occurred in 28th July 2009 and 14th September

2004), which never occurred since records began in 1957

(BWDB, Banani Station). Climate scientists also say that the

increased variability in rainfall also means longer drier spells

(no rainfall days) in between rain events. Again, there is

growing evidence that this is also happening.

Often it is heard that monsoon rainfalls does not occur like it

used to be earlier - 3 or 4 days of continuous rainfall. The

changing rainfall pattern creates challenges for drainage

engineers as the system was designed for a different pattern.

Performance of drainage system also depends on other

factors: solid waste management, sediments blocking drain

inlets, wastewater entering drainage pipes, unplanned &

uncontrolled urbanization filling up low lands and khals, etc.

For a city like Dhaka, the on-the-ground realities create more

of an impact than climate change, i.e. local effects can dominate

climate change impacts. Despite this notion, it is clear that

climate change is going to make existing bad situation worse.

IWM has shifted its focus from impacts to adaptation. Advanced mathematical tools, such as MIKE URBAN and MIKE FLOOD, are being tested on their effectiveness of such innovative ideas. IWM is presently looking at outside-the-box solutions, which involve multi-purpose or multi-functionality of infrastructure & land use in urban context; such as, lowering of the Dhopkhola Play ground to act as a "dry pond"

which can reduce urban flooding in Old Dhaka area.

Presently, important Master Plans for Dhaka are being prepared/ updated. IWM was involved in Wastewater Master Plan, which proposed disconnecting sewerage pipes from drainage system. Also Dhaka Detailed Area Plan (DAP) and Drainage Master Plan (DWASA) are currently being updated. Hence, there are clear opportunities to introduce systematic changes that can markedly improve urban drainage in Dhaka City. Similar opportunities also exist for other urban centres of

Bangladesh, e.g. Chittagong, Narayanganj, etc.

Expertise of IWM in the area of urban drainage design,

modelling & analyses is providing effective support to

practitioners (e.g. DWASA) and planners (e.g. NCC) to reduce

urban flooding problems. The solutions being proposed are

not only robust to the impacts of climate change but are also

cost effective, socially acceptable and environmentally friendly.

Water Availability, Demand and Adaptation Option Assessment

of the Brahmaputra River Basin due to Climate Change

The Hindu Kush-Himalayan (HKH) region is one of the

most dynamic and complex mountain systems in the

world. Himalayan Climate Change Adaptation Program

(HICAP) is undertaken to build climate resilient

mountain communities in the HKH having special focus

on women. A contract agreement was signed between

ICIMOD and IWM to carry out a study on the

Brahmaputra river basin focusing the present availability

and demand of water in the basin along with adaptation

option assessment under future climate change.

The study has been accomplished based on secondary data

and information available in the public domain. Hydrological

models of the Brahmaputra basin have been developed using

MIKE BASIN software of DHI and SWAT. Water availability has

been determined using model results. At the same time,

the impact of future climate change on water resources in

the basin has been analyzed using hydrological model and

climate change predictions of 4 climate models with 2 RCPs.

The monthly average water availability varies ranging from

around 8350 Mm3 in dry months to around 119860 Mm3

in wet months. With years, the change of flow in the basin

increases and becomes more significant in pre-monsoon

months: April, May and June. In future 2020, the average

change of flow is likely to be increased by an amount of 1.8 %

in October and that is as high as 4.6 % in May. In future 2050,

the same ranges from 4.5 % in August to 12 % in May.

Master Plan for Water Supply & Sewerage System of Dhaka

Dhaka city's water supply source's pattern is conjunctive use

of groundwater & surface water. In order to decrease the

dependency on ground water Dhaka WASA is planning to

harness surface water from the Rivers Padma and Meghna. To

improve efficiency and minimize loss of water DWASA is

establishing District Metered Areas (DMA)'s. The

implementation of these major projects needs

comprehensive planning, proper coordination to ensure

integration.

The Water Supply Master Plan for Dhaka City has been

undertaken by DWASA to prepare a 50 year Master Plan, to

identify priority investment projects and to recommend an

appropriate institutional framework. As a part of the project

IWM has undertaken a comprehensive assessment of existing

situation, developed strategies with stakeholder consultation

and devised short-term, medium term and long term plan.

The final recommendation will include financial analysis of

the proposed developments, organizational structure, policy

and regulatory framework, water rates, operation and

maintenance and strategic environmental assessment.

In order to provide sufficient sanitation coverage in Dhaka

City, DWASA undertook the sewerage master plan project at

the same period. The plan had a design horizon up to year

2035. The design of infrastructure for priority investments

included rehabilitation of the trunk sewer, collection sewer in

Gulshan, Banani localities, 4 pump stations along the trunk

main and augmentation of Pagla STP. The priority investments

are earmarked for the first phase of the Master Plan (2013 -

2015). Together with Grontmij A/S of Denmark, IWM worked

towards a decentralized, equitable master plan. The master

plan introduced trickling filter technology of wastewater

treatment for its simplicity and low cost operation and

maintenance. Sewer model was developed the first time for

Dhaka City and IWM independently designed 120 km length of

sewer collection pipe network using SewerGEMS for different

localities of Dhaka.

It is found that climate change

will not lead to any adverse

impact on the major water use

sectors: domestic, irrigation,

industry and livestock in the

Brahmaputra river basin for

satisfying the demand. No

adaptation measure could be

found to be essential in major

water use sectors against

climate change impact in the

Brahmaputra river basin.

However, the study reveals that

climate change impact in the

Brahmaputra basin may lead to

increase in monsoon flooding

which may necessitate

adaptation measures for

enhanced flood management

activities in the floodplains. The

model developed under the

study needs further updating

incorporating sufficient data

and information with special

attention in dry months. The

future upstream diversions in

China and India has not been

considered. If this happens then

the picture will change.

Bangladesh Water Development Board (BWDB) and Institute of

Water Modelling (IWM) jointly organised a workshop, titled

'Establishment of Monitoring Network and Mathematical Model

Study to Assess Salinity Intrusion in Groundwater in Coastal Area

of Bangladesh due to Climate Change' at BIAM Auditorium, Dhaka

on 08 October 2013.

Water experts in the workshop stressed the need for using

surface water in agriculture to save groundwater as the

global climate change emerges as a threat to the country's

water sector in the coming days.

"About 80% of irrigation water presently comes from groundwater

sources. Although we've huge surface water, we hardly explore it,"

Director General of Bangladesh Water Development Board (BWDB)

M Azizul Haque told at the workshop in the morning session.

He said arsenic contamination in aquifer is on the rise due to over

exploitation of groundwater, and if the present trend continues,

arsenic will enter the food chain, creating a new health hazard.

Senior Secretary of Ministry of Water Resources Shaikh Altaf Ali,

IWM Executive Director Prof Dr. M. Monowar Hossain, IWM Deputy

Executive Director Dr A.F.M. Azfal Hossain and BWDB Deputy

Director Dr Anwar Zahid, among others, spoke at the workshop.

Shaikh Altaf Ali stressed on access to safe drinking water to

be the first right of people and the study must be carried

out to identify how safe water is reserved in aquifer. "We

can't provide water to irrigation without preserving drinking

water for people…we may innovate drought-tolerant

varieties."

The country's coastal belt is 'the most vulnerable to climate

change', he said but the water resource is the most

vulnerable in this region.

"If we can't preserve minimum drinking water for those living

in coastal belt, millions of them will migrate to other places,

creating a new economic crisis. So, 'we can't destroy our

groundwater anyway'. Shaikh Altaf Ali said,

IWM Executive Director Prof Monowar Hossain said since

Bangladesh depends on the water of its trans-boundary

rivers, the country's southwestern region faces crisis each

year for lack of water.

Monitoring quality of groundwater is very complex; Prof

Monowar said, `IWM has made a model to assess the

groundwater quality'.
