Description :
Different transfer time measurements combined with morphometrical and sedimentological analysis were carried out on three talus slopes and two moraines during the rainy season. After injection of salt, the electrical conductivity of the water in slope deposits springs is monitored to estimate transfer velocities. The lag times estimated by the measurement of tracer velocity demonstrates that these slope deposits delayed the flow depending on the type of deposit. The delay is at least 24 h in the case of the talus slopes and more than 48 h in the case of lateral moraines.
