Description Générale

The Hydrologic Studies Unit, "ESH(2x1m)/S", is an equipment that allows the work in an autonomous way for the study of the behavior of the water inside the soil being able to carry out a wide variety of experiments thanks to the specifications of the equipment.

The equipment consists of a closed water circuit allowing the operation continuously or discontinuously, an important parameter when studying processes such as water level distribution around a well (stationary process) or water infiltration after precipitation (non-stationary process) using a single piece of equipment. The closed circuit consists of a water tank, a pump, a flowmeter, different flooding devices over the test area and a drainage system to recover the water.

The main element of the equipment is a stainless steel test tank that can be filled with different types of sand and whose inclination can be regulated by a lifting system. The sand tank has numerous pressure taps in the lower part that allow the study of the water level with the help of a panel of pressure gauges.

In addition, water can be supplied to the test tank by different precipitation devices consisting of: 8 adjustable valves (simulating rain), from an inlet tank (simulating a river) or from two lateral French wells (simulating groundwater).

The main advantage offered by this equipment is its versatility, allowing a high number of tests to be carried out, realistically simulating a soil with a very reduced space occupation and without special requirements.
