Alluvial aquifers with sustained surface water discharge downstream of dam
Alluvial aquifers are formed from particles such as gravel, sand, silt and/or clay deposited by fluvial processes in river channels or on floodplains. These deposits store and transmit water to varying degrees through inter-granular voids. These aquifers may have structures, such as dams, that modify the flow of both surface water and groundwater. Dams that provide a sustained release of surface water may increase recharge from the downstream channel into the alluvial aquifers, resulting in their saturation.
