Missouri River Lowland porosity - the percent of the bulk volume of a rock or soil that is occupied by interstices, whether isolated or connected transmissivity - The rate at which water is transmitted through a unit width of the saturated thickness of the aquifer under a unit hydraulic gradient confined aquifer. - bounded below and above by confining units. Water recharges a confined aquifer where it intersects an unconfined aquifer. As water enters it becomes pressurized by the weight of the water and the seal provided by the overlying confining unit. Water in a well drilled into it will flow into the well until the water level is above the top of the aquifer. Artesian well can be flowing if flowing above ground surface
