Measurement of Water Soil Erosion at Sparacia Experimental Area (Southern Italy): A Summary of More than Twenty Years of Scientific Activity

The main purpose of this article is to give a general idea the scientific activity that was carried out starting from 2000s on basis data collected in plots installed at Sparacia experimental station for soil erosion measurement Sicily, South Italy. paper includes presentation site, description methods and procedures measuring processes both available literature applied (sediment sampling water level reading storage tanks total measurements; profilometer, Structure Motion technique rill measurements), results obtained monitoring period site. latter concern effects plot size steepness loss, variability, frequency analysis characterization, comparison between interrill rates. Each these topics addressed with multi-temporal analyses performed increasing database, which allowed draw robust conclusions. Soil loss did not vary appreciably length contrast assumption made USLE/RUSLE. variability measurements runoff volume, sediment concentration event scale replicated decreased as mean measured value increased. normalized distributed according two-component distribution. A power relationship volumes lengths established. also confirmed morphological similarity channels rills ephemeral gullies described by dimensionless relationship. Rill erodibility sampled clay varied over time, maintaining relatively low values. Finally, dominant relative erosion, more efficient transport system through network occurred
