Hydrological processes and water resources management in a dryland environment IV：Long-term groundwater level fluctuations due to variation in rainfall
Long-term groundwater level fluctuations rainfall dryland environment
2009/5/26
To evaluate the effects of variations in rainfall on groundwater, long-term rainfall records were used to simulate groundwater levels over the period 1953-96 at an experimental catchment in south-east...
Hydrological processes and water resources management in a dryland environment III：Groundwater recharge and recession in a shallow weathered aquifer
Hydrological processes Groundwater recharge shallow weathered aquifer dryland environment
2009/5/26
In crystalline basement regions of Africa, shallow weathered aquifers provide vital water resources for rural communities. To quantify evidence of the behaviour of these shallow aquifers, groundwater...
