Description :
The paper introduces the results of the calibration of the runoff and sediment concentration measurement system adopted at the Masse experimental station to study erosion processes at the plot scale in Central Italy. Two soils of various particle size distributions were used in the calibration trials performed by the same field worker. The collected runoff is stored in cubic tanks equipped with ten taps for sampling the suspension. When an erosive event occurs, the plot runoff volume is measured by means of the water level in the tank, and the corresponding mean measured concentration in the suspension is quantified. The calibration curve allows the correcting of the mean measured concentration, quantified by the sampling procedure, in order to determine the actual concentration in the tank.
