Flood Modeller

• Modern and integrated interface

• Streamlined workflows

• Integrated Web Mapping Services

• File management

• Open file structure

• Enhanced productivity tools

• Robust, quick and reliable solvers

• Integration with 3rd

party software

5

• Provides a single access point for building, running and reviewing:

– 1D Networks

– 2D Floodplain models

– 1D/2D linked models

– Other 1D linked models, i.e. TUFLOW, SWMM, water quality, etc.

• Modular structure of multiple panels. Each panel can be:

– Docked and undocked

– Moved to different screens

– Resized

– Customized panel configurations can be saved against your username

8

• 1D Networks (.dat)

• 1D event files (.ied)

• 1D Initial conditions files (.zzs or .iic)

• Spatial datasets (i.e. grids, shapes, images, flood maps, etc.) – these layers do not need to be shown on map view

• Associated data (e.g. TUFLOW model files, calibration data, reports, analysis spreadsheets, etc.)

• Simulations:

– 1D scenarios (.ief)

– TUFLOW scenarios (.tcf)

– 2D (or 1D/2D) scenarios (.xml)

– 1D water quality scenarios (.qef)

– 1D batch runs (.ipf)

Flood Modeller GIS Layers Panel

Layers Panel

10

• Digital terrain models (i.e. ground grids). Compatible formats are:

– ASCII raster (.asc)

– Binary (.flt)

– ArcInfo grid (sta.adf)

• TUFLOW model files (.shp, .asc)

• TUFLOW results (.2dm / .dat)

• 1D flood mapping (.htn)

• Background mapping

– Aerial photos

– Map tiles

– WMS layers

Layers Panel

11

• 2D Build tab includes tools to “draw” new TUFLOW model components:

• Data created in shapefile format – option to export to MapInfo format

• Required TUFLOW attributes added automatically

• Existing TUFLOW MapInfo files can be viewed in map (auto-conversion to

shapefile)

Building TUFLOW Model Components

12

TUFLOW Code Layer

Click the TUFLOW

Active Area tool

13

TUFLOW Code Layer

Click to draw code

layer shape

Attributes automatically set

up (for combining with HX

and CN lines)

Attribute editor

Define “Code”

attribute and

assign value = 1

14

TUFLOW Boundary Line

Click the TUFLOW

Line tool

15

TUFLOW Boundary Line

Snapping settings

Snap to code layer for an

edge boundary line

Edit boundary line attributes:

- Need to enter type - “HX” or “CN”

- Need to enter factor “f” - for HX = 0,

for CN = between 0 and 1

Line draw tool

16

TUFLOW 1D / 2D Link Lines

Click the TUFLOW

Line tool

Load 1D GXY file

(as point shape file)

17


Snapping settings

Snap to both 1D

nodes layer and

boundary layer

18


Line draw tool

Edit boundary line attributes:

- Enter type = “CN”

- Factor “f” then auto-defaults to 1 (can be reset <1)

19

Editing Existing TUFLOW Model Data

• Shape files - use Flood Modeller Layer Editor to:

– Add new points, lines or polygons

– Move features

– Add or edit attribute fields

• MapInfo MIF/MID files

– Import as shape files

– Edit using shape file editing tools

– Export back to MapInfo format

• TUFLOW control file (tcf)

– Added as a simulation in the Project panel

– Selecting edit opens in text editor

20

• Load an existing 1D network

– Home tab of main toolbar, or

– Right-click menu in the Networks section of the Project panel

• Build a new 1D network

Creating 1D Simulations (1)

– Draw network on map; or

– Create network in table

(same as previous software)

– Double-click node icons to

specify properties

New unit icon

shown on map

and in table

Select unit to

add to network

21

• Select New 1D simulation from either:

– Simulation tab of main toolbar, or

– Right-click menu in the Simulations section of the Project panel

• Simulation definition window is displayed:

Creating 1D Simulations (2)

– Active 1D network is pre-loaded

– Simulation (.ief) filename can be

different to network name

– Drag event data files and initial

conditions files from project panel

22

• 1D / TUFLOW linked models are controlled from the 1D simulation (.ief)

file

• Links are specified in the links tab of the 1D simulation definition window:

– Browse to a TUFLOW .tcf file

– Drag .tcf file from Project panel

Linking Flood Modeller 1D to TUFLOW

• Note: Advanced parameter tabs initially

hidden - access from View menu

23

Running a 2D Only Model

• Flood Modeller - single interface to store all

model files as one “Project”

• Set up path to TUFLOW engine in Flood

Modeller settings

• Run simulation from control file (tcf) in Project

panel

– Option to edit control file in text editor

– Option to view results in map view

24

• Option to load all or selected time steps from 2D results

• 2D Flood Map tool to create flood maps (depth grids, outlines or animations)

• 2D Flood Map tool to calculate flood hazard maps

• Extract data from map view:

– Plot point time series

– Draw sections across floodplain

– Total volume crossing a section

• Display and record animations from 2D results

• Flood Viewer facilitates sharing of results with stakeholders

2D Flood Data Viewing Options

25

• Use 2D Flood Map Tool - select to output single result or batch multiple time steps

• Can use tool without loading (large) 2D results data into map view

• Output options:

– Flood maps

– Flood hazard calculation

– Flood volume calculation

• Output formats; depth grids, outline shapefiles, Google Earth

Creating a 2D Flood Map

26

• Extract underlying data from line in map view:

– Load line (polyline shape file)

– Draw line (uses measure tool)

Extracting Section Plots through 2D Results

27

• Flood Viewer facilitates sharing of results with stakeholders

Flood Viewer Tool

28

• Flood Modeller has GIS functionality designed to offer useful tools specifically for

modelling

• We envisage Flood Modeller to work in tandem with other GIS software

• GIS tools Flood Modeller provides can be grouped into following categories
