RSES Simulateur de Pluie pour l'Étude de l'Érosion des Sols

The Rainfall Simulator for Soil Erosion Studies, "RSES", consists of a metal frame that can be placed directly on the ground for direct field studies or used with its various accessories for laboratory tests. The whole structure is covered with a transparent curtain to avoid splashing.

At the top is supported the rain spray device consisting of a spray nozzle and a horizontal rotating disk controlled by a variable speed motor allowing to obtain variations in the intensities of the induced precipitation. The water coming out of the nozzle hits the rotating disc, which is formed by two circular plates, with segmented openings allowing the adjustment of the opening for the water fall.

A water storage tank with level switch is included, from which water is pumped to the rain sprinkler by means of a pump and a regulating valve. The water is metered by means of a flow meter.

Depending on the opening of the rotating disc, a certain amount of incoming water is sprayed and the rest is recirculated back to the tank.

Different accessories such as rain gauges, different test plots, tilting stand, etc. are included.
