Unconfined Aquifer and a Simulated Karst-type Aquifer
The ground water flow models are used to demonstrate ground water movement
principles. The model is constructed with clear plexiglass which allows
viewers to watch how the water within a ground water system moves. The
movement of water towards a pumping well can be easily observed.
The Karst model includes an
unconfined aquifer and a simulated Karst type aquifer. Water is introduced into the
model using inverted quart jars at the ends of the model. A vacuum pump
is used to "pump" water from the two wells; one well is in the
unconfined aquifer, the other is in the confined aquifer. Observation
wells show the ground water flow patterns as the wells are pumped. Colored
water is used to easily demonstrate the water movement patterns. Colored
water can also be used to show how contaminants might move within a ground
water system. The "contaminants" can be introduced at the surface
or injected at three points within the aquifer.
The models are
shipped in a carrying case, completely packed and ready to operate with
the necessary accessories including: a hand operated vacuum pump, flask
to receive "pumped" water, water supply bottle, syringes for
injecting "pollutants," and an operators manual.
Models built to reflect specific
site geologic conditions can be constructed on special request and at
additional cost. See the order
form for prices.
