Surface Water Interaction Modelling Using Visual MODFLOW and GIS

PHYLARESResults and Discussion / ch.8_________________________________________________________________________________568.3 Groundwater headThe head distribution output of the model is considered as an important hydrological parameterto characterize the flow system, in that it measures the energy of flow, and can also be used tocalculate the direction and rate of movement of the groundwater. Figure 8.4 indicates thegroundwater head and flow direction 1. From this figure it can be observed that flow is fromhigher heads which are on the Southeast and Northwest parts of the model to lower heads whichare mainly located around the river.Figure 8. 3 Ground water heads and flow directions in Layer 1Figure 8.4 to Figure 8.6 show the equipotential head distribution and flow direction ofgroundwater across the three layers of the model.______________________________________________________________________________________Groundwater – Surface water interaction modeling using visual MODFLOW and GIS
