Introduction:This exercise will utilize Activity 12.3 (Floridan Limestone Aquifer) on page 325 of your Physical Geology Lab Manual. You may need to review the Chapter 9 on Topgraphic Maps and Orthoimages, specifically, the section on rules for contour lines (Figure 9.12)Directions:1) Read Laboaratory 12: Groundwater Processes, Resources and Risks in you Physical Geology Laboratory Manual2) Using the Sulphur Springs, Florida 7.5’ Quad (Figure 12.6), transfer the provided lake elevations (blue italicized numbers on the lakes) onto the blank sketch map on page 326.3) These lake elevations can be considered points of known topographic elevation of the water table in the Sulphur Springs Quadrangle region. Using methods of interpolation and extrapolation described in Figure 9.12 (Rules for Contour Lines), draw in the contour lines in 5 foot intervals (eg. 30 ft, 35 ft, 40 ft. 45 ft, 50 ft).4) The direction of groundwater flow (flow lines) in a region can be represented by arrows drawn perpendicular to the contour lines with the arrows pointing in the direction of lower elevations (see Figure 12.1: Water movement through an unconfined aquifer). The collection of flow lines drawn on a map for a given region is referred to as the flow net. Draw the flow net for the Sulphur Springs Quadrangle sketch map.5) Submit this completed sketch map to the instructor. You can either scan and attach this map to an e-mail or fax it to the instructor. You may also take a picture and attach it to an e-mail, but make sure the picture is of high enough resolution for the instructor to make out the details of your work.6) Complete the accompanying Groundwater Lab Exercise. This exercise consists of 16 multiple choice questions based on the information in the “Laboratory 12: Groundwater Processes, Resources and Links” and the work you completed on the Sulphur Springs Quadrangle sketch map.
