Alluvial aquifer

Groundwater. 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).

Alluvial aquifer. MSR, the main recharge component in arid and semi-arid basins, involves two related processes: mountain front recharge (MFR) and mountain block recharge (MBR). MFR is recharge from stream runoff at mountain fronts to the adjacent alluvial aquifer while MBR is recharge through mountain bedrock (Houston, 2002, Meixner et al., 2016).

Aquifers underlying the Mississippi Alluvial Plain help sustain a vibrant agricultural region that is experiencing conflicts and concerns over groundwater availability. The Mississippi River Valley alluvial aquifer is the primary source for supply of irrigation from groundwater.
