Ground Water Flow Unit .
Specification of Ground Water Flow Unit
- A bench-standing sand tank capable of demonstrating, on a small scale, the hydrological principles of ground water flow.
unit allows simple three dimensional flow situations to be set up
quickly and measurements of piezometric levels taken at appropriate
positions within the model under study.
- The accompanying instruction manual describes six basic demonstrations of importance in Engineering Hydrology.
Description of Ground Water Flow Unit
sand tank is manufactured in glass reinforced plastic for durability in
service and is located in a painted mild steel frame which is designed
for standing on a laboratory bench.
- A diffused water
inlet/outlet with associated flow control valve is installed at each end
of the sand tank. This facility allows the desired water table to be
established for the various demonstrations of groundwater flow.
wells with control taps in the base of the tank allow studies of
abstraction. Nineteen tappings in the base of the tank arranged in a
cruciform configuration are connected to a multi-tube manometer on the
side of the tank. These indicate the profile of the water table in the
sand. A sliding cursor permits measurement of any level.
