Description:

This exercise is done in a computer lab using ESRI ArcMap software with both the Spatial Analyst and 3D Analyst extensions. Students are given a copy of the Lakeside Nebraska 15 minute topographic map and a shapefile containing all the lake elevation data. They are given instructions on how to rasterize the point data to create a contour map of the water table surface and are then shown how to create flow lines. Their task is to create a flow net that they will use to determine areas of groundwater recharge and discharge. They will then generate hypotheses to explain what controls the groundwater flow system in this area.
