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...
Hydrological processes and water resources management in a dryland environment II：Surface redistribution of rainfall within fields
Surface redistribution rainfall within fields Soil water movement
2009/5/26
Soil water movement was studied within fields on two different soil types, a red clay soil and a duplex soil of sand over clay, at the Romwe Catchment in southern Zimbabwe. Each study site comprised t...
