Daily Objectives #3 (September 4, 2007) Dr. Sanders

By the end of today's class, you should be able to do the following:

v Wells and Ground Water Systems:

If the weather is good: Measure depth to water in a well and the total depth of the well. Extract water from the well and describe the effect of that extraction on the water level over time. Sketch a diagram illustrating the components of a well. Develop a test protocol for evaluating how a well responds to pumping. Information on what we are doing outdoors appears at this link.

NOTE: The remainder of the material here is what we would be doing if we were staying indoors due to rain this evening. But the weather is great! So we'll do it later this week/semester.

If the weather is not good: Using the ground water flow model, inject dye into the model and track its flow through time. Sketch a diagram showing the following features:

    q surface water
                q    ground water
    q boundaries of the flow system
    q flow directions (use arrows)
    q flow velocities (show areas of fast/medium/slow flow)

v Water Flow: Describe in words what makes water flow. Using simple sketches, show how water would flow from one container (like a rain barrel) into another if they were connected by hoses. Explain what would make water flow from one portion of a saturated porous medium (e.g. sand with water in it) to another portion of the same medium.

v Drainage basins: Explain in words what a drainage basin is. Using a topographic map, select any point on a stream and delineate the drainage basin for that point.
