Study of hanging valley in loess-paleosoil sediments with soil erosion assessment using nuclear and erosion potential methods

This paper is dealing with soil erosion assessment using two different approaches: nuclear model and potential method, also known as Gavrilovic's method. Complex valley systems on Titel Loess Plateau were selected for investigation. Radiocaesium favored in many studies an optimal tracer due to its relatively long half-life, negligible renewal the environment strongly binding ability onto particles. The use of gamma-spectrometry environmental testing laboratories acts a precise fast measurement technique determination 137Cs activity concentrations, without need complicate preparation samples. Annual deposition rates estimated according three conversion models uncultivated land: profile distribution years dominant fallout (1963 1986) diffusion migration WALLING software. applied validated by comparison which most relevant empirical processes torrent valleys. obtained results indicate good agreement overall low values average annual all profiles investigated area. Correlation analysis has determined influence slope, terrain curvature, vegetation index models.
