Cs382/Soil Density Experiment
From Earlham Cluster Department
This is a detailed description of one experiment listed on the CS382 course page
The goal of this experiment is to determine the density of the soil contained within the groundwater simulator.
- enVision sand and gravel groundwater simulator
- method of measuring water
- Empty the groundwater simulator of water and allow it to dry as much as possible.
- Close the ocean valve.
- Fill the aquifer compartment with a known amount of water such that the water level stays below the aquitard.
- Measure the inner dimensions of the aquifer compartment (width and depth) making sure to not include the thickness of the walls in your measurements.
- Measure the distance from the bottom of the inner compartment to the top of the water level.
- Calculate the volume of space, <math>v(w2)</math>, filled by the water that you put into the simulator (<math>width * height * depth</math>)
- Convert the known amount of water you added to the simulator (<math>v(w1)</math>)into the units of measurement you used for <math>v(w2)</math>.
- Calculate the soil's density as <math>(v(w2)-v(w1))/v(w2)</math>
- How might you repeat this experiment to determine the soil density of the sand in the simulator?
Considerations for a Computer Based Simulation
- How might you represent the soil density measured here in a cell based simulation? Agent based simulation?
