Groundwater is an important source of water stored in the earth, deep beneath our feet, in what are called aquifers. Aquifers are the collective saturated spaces between many layers of sands, soils, and gravels (called alluvial aquifers), or the interconnected cracks in bedrock or volcanic deposits (called fractured rock aquifers).The alluvial aquifer of Upper Cheliff (northern Algeria) is known for its intensive agricultural activities, which is based especially on groundwater exploitation. This aquifer is now facing a dual problem of quantity and quality, with a decrease in the groundwater levels and an increase in mineralization. Twenty monitoring samples were …Rates of groundwater loss often exceed the rate of recharge due to excessive pumping or drought, which causes water levels in aquifers to drop. This disparity between recharge rates and groundwater losses led to water level declines during 2001-2006, ranging from 0.6 to more than 21 feet in many major Oklahoma aquifers, as shown in Figure 1.

Many unconfined aquifers are alluvium or terrace aquifers, meaning they were formed in alluvial deposits and interact closely with adjacent streams and rivers. Examples in Oklahoma include alluvium or terrace aquifers adjacent to the Cimarron, North Canadian and Arkansas rivers.

The uppermost aquifer consists of the alluvium (or the "alluvial aquifer"). Since there is no layer between the surface and the alluvium, the alluvial aquifer is not bounded above. Based on the 100-fold difference in hydraulic conductivity, the alluvial aquifer is bounded below by the limestone unit.Alluvial aquifers. Alluvial deposits are sediments composed of gravel, sand, silt or clay deposited in river channels or on floodplains. They occur in most regions of Australia and are a major resource for irrigation, town, stock and domestic uses.
