Legal Framework
National Water Act, 1998
(Act 36 of 1998)
Resource Quality Characteristics
Resource quality = Characteristics
Resource Quality:
1. the quantity, pattern, timing, water level and assurance of instream flow;
2. the water quality, including the physical, chemical and biological characteristics of the water;
3. the character and condition of the instream and riparian habitat; and
4. the characteristics, condition and distribution of the aquatic biota.
Geomorphological
Geomorphological processes
• Rivers migrate
naturally
• Erosion and
deposition
• Hydraulic sorting
• Flow – sediment

S21 Water Uses
6
Water Resource vs. Watercourse
Watercourse
• A river;
• A spring;
• A natural channel in which water flows regularly or intermittently;
• A wetland; lake or dam into which, or from which, water flows; and
• Any collection of water which the Minister may, by notice in the Gazette, declare to be a watercourse, and a reference to a watercourse include, where relevant, its bed and banks.
WETLANDS - Types
• Hydro geomorphic (HGM) classification system classifies wetlands according
– Form (geomorph-characteristics)
– The way in which water moves in, through and out of the wetland system (hydro-characteristics)
Floodplain
• HGM classification system recognises 5 generic palustrine wetland types, namely:
– Pans and depressions including lakes;
– Seepage wetlands;
– Unchannelled valley bottoms;
– Channeled valley bottoms; and
– Floodplains.

Extent of a Watercourse

Extent of a Watercourse
Extent and ‘Regulated Area’ =
Outer edge of the Riparian habitat / 1:100
flood line (whichever is greatest)
‘Regulated Area’ =
Within 500 m radius from the
boundary (extent) of a wetland

Extent of watercourse
WETLANDS - Definition
• Land which is transitional between terrestrial and aquatic systems where the water table is usually at or near the surface, or the land is periodically covered with shallow water
• Supports vegetation typically adapted to life in saturated soil

Activity can impact on any of the ecosystem drivers or responses and this will have a
knock-on effect on potentially all the other drivers and or responses
This will impact on ecosystem services provided

Hydropedology - interflow
Different soil types have specific hydrological properties
• Recharge soils
• Interflow soils
– Deep
– Shallow
• Responsive soils
– Wetland soils
– Shallow soils on impermeable material (hard rock, hardpan
carbonate, prismacutanic B)

of river systems
River continuum All rivers form a continuous longitudinal ecosystem
being progressively and continuously modified downstream from their headwaters to the sea

GA’s and Future Alignment
• GA 1199 replaced by GA 509 26 August 2016
• Risk Assessment Matrix to determine Entitlement
• GA’s now possible within 500m of wetlands
• Table of Catchments excluded - removed
• Maintenance and Emergencies are included
• River Management Plans are included
• Rehabilitation – not contemplated in GA1198
• Appendix D1 and D2 lists activities GA’d
42
43
OLD GA1199 (2009) NEW GA 509 (2016)
No GA within 500 m from wetlands GA’s possible anywhere – decided by
Risk Matrix as standardised method for
determining risk to resource quality
No GA in certain catchments listed Table with catchments removed – GA’s
possible anywhere in SA
No provision for maintenance Maintenance on ELU can be GA
No provision for rehabilitation (only
GA1198)
Rehab other than that contemplated in
GA1198 (WfW) can be GA
No provision for River or Storm Water
Management plans
River or Storm Water plans approved by
DWS can be implemented as GA
No Provision for Emergencies Emergencies can be handles ito
Emergency Protocol and is a GA
No provision for specific activities like
State Owned Companies and others
Specific activities were GA’s outright
only have to comply to conditions
GA’s and Future Alignment
Mainly aimed at taking LOW Risk activities out
of mainstream licencing – focus on
Compliance Monitoring

RATING CLASS MANAGEMENT DESCRIPTION
1 – 55 (L) Low Risk
Acceptable as is or consider requirement for mitigation. Impact to watercourses and resource quality small and easily mitigated. Wetlands may be excluded.
56 – 169 M) Moderate Risk
Risk and impact on watercourses are notably and require mitigation measures on a higher level, which costs more and require specialist input. Wetlands are excluded.
170 – 300 (H) High Risk
Always involves wetlands. Watercourse(s) impacts by the activity are such that they impose a long-term threat on a large scale and lowering of the Reserve.
