  An investigation was conducted to assess the recharge of an alluvial channel aquifer that is located in Southern Africa. The investigation utilized stable isotopes, groundwater levels response to rainfall and infiltration tests as complimentary tools to identify and understand groundwater recharge processes of the alluvial channel aquifer. The alluvial channel aquifer is characterized by shallow water table conditions (<3 meters below ground level) and quick groundwater level response to rainfall events thereby justifying the application of the water level fluctuation (WLF) method to estimate recharges rates of the aquifer system. The recharging of the alluvial channel aquifers occurs through high preferential infiltration rates as enhanced by pathways created by tree rooting systems. Cavities and holes created by the burrowing animals also contribute to high infiltrations rates al.. Read More»
