Revision as of 09:03, 13 February 2013
Artificial aquifer recharge (AR) is the enhancement of natural ground water supplies using man-made conveyances such as infiltration basins, trenches, dams, or injection wells. Aquifer storage and recovery (ASR) is a specific type of AR practiced with the purpose of both augmenting ground water resources and recovering the water in the future for various uses.
Climate change considerations
- More storage capacity needed to overcome seasonal dry periods and to reduce floods.
- Higher rainfall intensities may exceed infiltration capacities. Create storage, enhanced infiltration or artificial recharge.
- Lower rainfall results in the need for transport and storage of water from other areas.
- Changes in vegetation will cause changes in evapotranspiration, surface runoff, erosion and sediment transport/deposition. This requires water and soil conservation measures, like terracing.
