Groundwater Distribution and Aquifer Characteristics of Intrusive and Volcanics of Rift Valley5.1. Geologic and Structural Setting. The Rift Valley is a Cainozoic intracontinental rift system separating the Somalia subplate from the rest of Africa (Chorowicz, 1992, Delvaux et al., 1992, Smith and Mosley, 1993).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)3.2.1 Unconfined Aquifers. Aquifers which are bounded by a free surface (known as ‘water table’) at the upper boundary and a confining layer at the lower boundary are called unconfined aquifers (Aquifer 1 in Fig. 3.1). At the water table, water is at the atmospheric pressure, and hence unconfined aquifers are also called ‘water-table ...
