Aquifer characteristics
What are the two features of a good aquifer? An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel.

An aquifer is an underground layer of porous rocks or permeable rocks that store and retain groundwater levels in the soil. The underground aquifer is built with all types of porous or permeable rock materials, such as sand, gravel, or silt, making it a suitable water absorber. The rainwater enters the aquifer through the soil ... Aquifers are the geologic layers that are filled with water and that can transmit enough water to supply a well under normal hydraulic gradients . Aquifer Types Geologic materials can be classified as consolidated rock or unconsolidated (loose) sediment. Consolidated rock may consist of such materials as sandstone, shale, granite, and basalt.
1.3.1 Aquifer Characteristics 1.3.2 Transmissivity . This can be defined as the capacity of reservoirs (aquifer) to transmit water and it is denoted by T. The transmissivity of an aquifer equals the hydraulic conductivity of the aquifer multiplied by the saturated thickness of the aquifer. Thus, mathematically, T = Kb ————-(1)The recent research is carried out to model the characteristics and productivity of the groundwater aquifer in the Omdurman area, Sudan, by combining electrical resistivity and pumping test methods.

Oct 6, 2023 · Aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. Wells drilled into aquifers are important sources of fresh water. Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow; large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s. Different conceptual models, known from the literature, attempt to take into account all these particularities ...
