ESHC(2x1m)/S Computer Controlled Hydrologic Studies Unit

The Computer Controlled Hydrologic Studies Unit, "ESHC(2x1m)/S", allows the work in an autonomous way for the study of the behaviorof 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 whenstudying processes such as water level distribution around a well (stationary process) or water infiltration after precipitation (non-stationaryprocess) using a single piece of equipment. The closed circuit consists of a water tank, a computer controlled pumping, flow sensor,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 beregulated by a lifting system. The sand tank has numerous pressure taps in the lower part that allow the study of the water level with thehelp of pressure sensors.

In addition, water can be supplied to the test tank by different precipitation devices consisting of: 8 adjustable valves (simulating rain), froman 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 asoil with a very reduced space occupation and without special requirements.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + aControl Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, forcontrolling the process and all parameters involved in the process.
