WebAquifers are underground layers of very porous water-bearing soil or sand. Aquitards, by contrast, are compacted layers of clay, silt or rock that retard water flow underground; that is, they act as a barrier for groundwater. Aquitards separate aquifers and partially disconnect the flow of water underground. Also known as cap rocks, aquitards ... WebGroundwater. Groundwater is the water beneath the land surface that fills the spaces in rock and sediment. It is replenished by precipitation. Under natural conditions much of that recharge returns to the atmosphere by evapotranspiration from plants and trees or discharges to surface waters.

WebSep 9, 2014 · The Hidden Costs of Groundwater Overdraft. Groundwater overdraft occurs when groundwater use exceeds the amount of recharge into an aquifer, which leads to a decline in groundwater level. This condition is occurring in an increasing number of groundwater basins throughout California, and is impacting the state in many ways. WebGroundwater moves very slowly from recharge areas to discharge zones. Flow rates in aquifers are commonly measured in feet per day. It might take years, decades, or even centuries for water flow through some aquifers. Flow rates are much faster where large openings exist, such as in fractured basalt or coarse gravel.

Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also enco…

WebAn unconfined aquifer can also occur as a perched aquifer. Most commonly, perched aquifers form and are maintained by recharge that accumulates on aquitards in the vadose zone.
