Valescure plot experiment

The data set focuses on a 10-m2 plot within a granitic hillslope in Cevennes mountainous area in France, in order to study infiltration and subsurface hydrological processes during heavy rainfalls and flash floods. The monitoring device included water content at several depths (0-70cm for the shallow soil water; 0-10m for the deep water) during both intense artificial and natural rainfall events, chemical and physical tracers.<br />

Observing strategy: <br />
The experimental plot (lat = 44°05’39”N, long = 3°49’29”E) was set up from the 18/04/2014 to the 12/09/2016. It was located in a 30° hillslope, over a 10m2 rectangular area (2.50 m x 4m, the longer along the slope). <br />
The sprinkling device was made of four 2.50 x 1 m2 panels through which the rainfall was delivered by a drop by drop device (photo 1). The water was injected by 2 pipes for each panel, and the rainfall intensity delivered in each pipe was measured by a gauge. At the total, 8 gauges worked independently, controlling the rainfall intensity of both the right and left part of each panel.
