Alluvial aquifers are shallow (<50 feet) with water yields that can vary tremendously due to the influence of aquifer properties and the spatial distribution of recharge and pumping stress. There is rapidly increasing demand for water in the region by rural water systems, irrigators, livestock producers, and rural communities and these demands ...Although the bedrock aquifer contains more than 50 times as much water in storage as the alluvial aquifer, it does not store and transmit water as readily as the alluvial aquifer. For example, about 91 percent of the water pumped from wells is obtained from the alluvial aquifer, yet water-level declines generally have not exceeded 40 feet. The transmissivity of the alluvial aquifers in the grabens vary between 0.5 and 500 m 2 /day. The aquifers of the adjacent volcanic highlands have lower transmissivity (1-100 m 2 /day). In recent years many water wells were drilled in the Raya and Kobo valleys for large-scale irrigation ( Aytenfsu and Zemedagegnhu, 2003 ).Shallow alluvial aquifer is more contaminated with high spatial variability. • U levels are higher along the groundwater flow direction in the SW direction. • EC, Na +, K + and HCO 3 − ions are primarily governing the behaviour of uranium. • Weathering of carbonates is a major cause of uranium mobilization in the aquifers. •Sediment particle size decreases in the tail of this typical alluvial-lacustrine geological unit, the thickness of the surface low-permeable layer becomes larger, and groundwater flow becomes more sluggish, thereby forming a more reducing subsurface environment in the tail of GRD (Choi et al., 2016).Local aquifer (by name) -- For groundwater sites, you can also select the local aquifer that the wells are completed in.

An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it. Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone. Other rocks can be good aquifers if they are well fractured.Jun 7, 2023 · Alluvial aquifers are generally shallower than sedimentary and fractured rock aquifers and water levels often fluctuate due to varying recharge and pumping rates. Due to their shallow and unconfined nature, alluvial aquifers are susceptible to contamination and pollution. 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.Lotikipi and Lodwar aquifers Alluvial sands and sediments, which range up to 80 m deep.
