Reminder: Homework #1 is due at class
Daily Objectives #3 (September 4,
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
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.
q surface water
- 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
q boundaries of the
q flow directions (use
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.
