Techniques for increasing aquifer recharge in semiarid regions
- Resumen
- Principal potential methods for recharging aquifers in semiarid regions are presented. Scarcity of water resources in semiarid regions is often accompanied by brief periods of highly intense precipitation that can generate potentially catastrophic floods. In such areas, runoff water can be harvested for aquifer recharge providing valuable contributions to flood prevention and the management of water resources. We present a study undertaken in the south-eastern Spain in which the recharge from several check dams is calculated, as well as that from various gravel pits excavated to provide gravel for use in greenhouses. The gravel pits are situated in the apical sectors of alluvial fans overlying hydrogeological units that are widely overexploited, so they are wellpositioned for use for artificial recharge. The study demonstrates the high hydrogeological efficiency of such gravel pits for this purpose.
