In the paper the dynamic of the random roughness along a sequence of simulated rainfalls occurring on a ploughed soil has been studied. The relations between this dynamic and that of the runoff and the concentration have also been discussed. The experiments were performed in a replicated 1m x 1m square plot, located in a 16% slope in a silt-clay-loam soil and equipped with a nozzle-type rainfall simulator. Each experiment started from a just ploughed surface and included a sequence of 3 simulated rainfall carried out in the range of few days. The independent variable along the three subsequent simulations of each sequence is the initial soil surface condition, that is progressively modified by the rainfall runoff process.

Abstract
In the paper the dynamic of the random roughness along a sequence of simulated rainfalls occurring on a ploughed soil has been studied. The relations between this dynamic and that of the runoff and the concentration have also been discussed. The experiments were performed in a replicated 1m x 1m square plot, located in a 16% slope in a silt-clay-loam soil and equipped with a nozzle-type rainfall simulator. Each experiment started from a just ploughed surface and included a sequence of 3 simulated rainfall carried out in the range of few days. The independent variable along the three subsequent simulations of each sequence is the initial soil surface condition, that is progressively modified by the rainfall runoff process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
