The University of Nebraska's Groundwater Flow Model is shipped in its carrying case, completely packed
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 operator's manual.
Uses of the Model
The model can be used in many different settings. It is especially effective
with youth in school classrooms, for children's festivals, and with Boy
and Girl Scout and 4-H groups. Also, the model can attract significant
attention when used in conjunction with water educational displays. It
can be useful in presenting basic septic system/ground water information
to adult audiences in various types of meeting and workshop formats. Because
of the model's size, it must be used with relatively small groups.
The models are constructed
by the Biological Systems Engineering Research Development Shop at the
University of Nebraska-Lincoln, adapted from an original design by the
University of Wisconsin-Stevens Point. It takes 3 to 4 weeks from the
time the order is received for the model to be built. The model is 24
inches long, 12 inches tall, and approximately 2 inches wide. The weight
of the model with case is about 40 pounds.
In Nebraska, many Extension County Offices and Natural Resource Districts (NRD) have purchased
the models. Extension and NRD staff are often available to provide demonstrations
using the model. In some cases, the models may be available for loan.
Contact your local Extension or NRD office to determine the
availability of a model in your area.
