Groundwater Gradient Exercise Geology 210 Objectives: In this lab we will perform the following tasks: 1) Measure water levels in six wells located on the edge of the CSUS campus. 2) Plot the results from shallow and deep wells on two different maps. 3) Construct three point problems to determine the direction of groundwater flow in shallow and deep wells. 4) Write a technical report that summarizes results. Equipment needed: Ruler or engineering scale, calculator Today’s exercise: 1) Measure water levels in the three shallow wells and three deep wells. These water levels must then be converted to elevations above or below sea level (note: the common abbreviation for sea level is MSL or “Mean Sea Level”). Use the following formula to calculate the elevation of the water table above or below sea level: (Land surface elevation) - (Measured water level) = Elevation (MSL) Record your results on this table: Well number Land surface elevation (surveyed elevation at top of casing) Measured water level in well (from land surface to water table) Elevation of water table (MSL) MW-1 MW-1A MW-2 MW-2A MW-3A MW-3A

2) Plot the water levels (MSL) for the shallow wells on the map labeled “Shallow wells". Plot the water levels (MSL) for the deep wells on the map labeled “Deep wells". 3) Construct a graphical three-point problem to determine the direction of groundwater flow for each of the maps.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
