BASIC HYDROLOGY APPARATUS
GENERAL DESCRIPTION
The apparatus is a self contained unit for studying basic hydrology.
It consists of a large stainless steel
rectangular tank with adjustable tilting mechanism. The tank is filled
with a granular medium. Two separate sets of four spray nozzles above
the tank simulate rain fall on the catchments. The tank upper walls are
transparent. Valve control of the nozzles varies the lag time on the
hydrograph to simulate a moving storm.
The compartments at each end of the tank
are connected to the catchment area by wire mesh to allow flow between
the compartment and the catchment. Two wells with valve control are also
provided at the middle of the tank. Twenty pressure tappings along the
orthogonal axes of the tank to measure water table profile by a
manometer bank.
A metal frame supports the tank and
houses a storage tank. Water is drawn from the storage tank by a pump
and separately supplied to the overhead nozzles and/or the two end
compartments via a flow meter and pipings with valve control. Run-off
from the catchment is measured by a calibrated rectangular weir or
returns directly to the storage tank.
TYPICAL EXPERIMENTS
- Investigation of rainfall/runoff relationships for dry, saturated
and impermeable catchments of various slopes for surface runoff.
- Effect of interflow on outflow hydrograph
- Simulation of multiple and moving storms.
- Cone of depression for single well and interaction of cones of depression for two adjacent wells.
- De-watering of excavation sites by use of wells.
- Flow from a well in a confined aquifer.
- Demonstration of watersheds for a simulated island with rainfall and well flows.
- Sediment transport and meanders in simulated rivers.
