Surface Water Interaction Modelling Using Visual MODFLOW and GIS

PHYLARESInteraction of Groundwater and Surface water / ch.3__________________________________________________________________________________________13Figure 3. 2 Interaction of streams and ground water. (Winter et.al, 1998.)In Figure 3.2, (A) represents gaining streams that receive water from the ground-water system,whereas losing streams (B) lose water to the ground-water system. For ground water to dischargeto a stream channel, the altitude of the ground water table in the vicinity of the stream must behigher than the altitude of the stream-water surface. Conversely, for surface water to seep toground water, the altitude of the water table in the vicinity of the stream must be lower than thealtitude of the stream surface. Some losing streams (C) are separated from the saturated groundwatersystem by an unsaturated zone.______________________________________________________________________________________Groundwater – Surface water interaction modeling using visual MODFLOW and GIS
