Assessing Soil Erosion by Monitoring Hilly Lakes Silting

Soil erosion continues to be a threat soil quality, impacting crop production and ecosystem services delivery. The quantitative assessment of erosion, both by water wind, is mostly carried out modeling the phenomenon via remote sensing approaches. Several empirical process-based physical models are used for estimation worldwide, including USLE (or RUSLE), MMF, WEPP, PESERA, SWAT, etc. Furthermore, amount sediment produced phenomena obtained direct measurements in experimental sites. Data collection this purpose very complex expensive; fact, we have few cases measures distributed at basin scale monitor phenomenon. In work, propose methodology based on an expeditious way volume hilly lakes with GPS, sonar sensor aquatic drone. means automatic GIS procedure lake depth surface area. Hilly can considered as containers. Time-lapse make it possible estimate silting rate lake. 12 Tuscany was measured 2010 2018, results terms were compared estimates loss RUSLE MMF. analyses show that all subject phenomena. estimated corresponds well used. relationships found significant promising application methodology, which allows rapid Substantial differences proposed comparison (mainly two cases) justified particular conditions site, difficult predict from models. approach monitoring basin-scale extended larger domains lakes, such as, example, region, where there more than 10,000 lakes.
