Un nuovo campionatore per la misura della perdita di suolo in parcelle attrezzate

Risultato della ricerca: Paper

Abstract

Plot soil loss measurements need the knowledge of the weight of the soil material delivered at the plot lower end. The Sparacia experimental area is equipped for measuring plot soil loss. The runoff and associated sediments are intercepted by a gutter placed along the lower end of the plot and collected into a storage system consisting of tanks. Use of a new sampler for measuring the sediment collected into the tanks is proposed. The sampler is a brass cylinder of known diameter with a gate valve located at its end section. Infixing sampler and closing the valve allow to extract a column representative of the turbid suspension collected into the tank. To validate the sampler, experiments were carried out using both cylinders with a diameter equal to 20 cm and a tank having a quasi-square horizontal crosssection with an area equal to 1 m2. The measurements demonstrated a good reliability of the sampler to reproduce the actual concentration of the suspension. Only for lowest concentration values a small corrective factor needs for taking into account an imperfection of the valve closure system.
