1. Ecological and Environmental Impacts of Large-scale Groundwater Development in the Table Mountain Group (TMG) Aquifer System WRC project K5/1327

2. WRC – TMG Introduction Objectives of the WRC Eco TMG project

Project process and timing
Links with CCT-TMG AA project
Differences to CCT-TMG AA project.

3. Aims of the WRC project
Characterize the occurrence of groundwater discharge areas in the TMG;
Characterize the hydraulic continuity between discharge areas and deep and shallow aquifer flow regimes;
Characterize groundwater use by terrestrial and aquatic ecosystems;
Assess the dependency on groundwater of these uses and the sensitivity of ecosystems to changes in the groundwater regime;
Determine early indicators of stress and response to changes in the groundwater regime;
Assess the resilience of ecosystems to changing groundwater conditions at various temporal and spatial scales.
