Development and testing of the Revised Morgan- Morgan-Finney (RMMF) soil erosion model under different pedological datasets

Popis výsledku v původním jazyce

The study aims to investigate the effect of soil properties delineation on erosion modelling. To that end, the soil attributes of the Venetikos River catchment, northwestern Greece, are described using two pedological datasets, i.e. field samples and classification maps. The goal is to select the most appropriate for the accurate estimation of erosion. The Revised Morgan-Morgan-Finney (RMMF) model is developed per base map (annual or multi-annual), keeping all other parameters unchanged. Modelled sediment yield (SY) values are validated against observed ones, calculated utilizing the sediment rating curve methodology. Overall, the classification maps approach (164,35 t km2 year) performed better than the soil samples one (82,97 t km2 year), displaying higher convergence to the synthetic SY (548,9 t km2 year). The discrepancy among approaches is attributed to the different computation methodologies (thus pedological background) used. Both approximations successfully identified the high-risk
