Soil Erosion Prediction at the Water Reservoir’s Basin of Pineios Dam, Western Greece, Using the Revised Universal Soil Loss Equation (RUSLE) and GIS
2018
It’s widely known that the procedures of soil erosion are affected by a number of physical and
human factors and are appeared with different intensities in different places. However, the spatial and temporal
scales of these procedures are still poorly understood. Therefore, the control and prediction of soil erosion and
deposition are a complex and difficult task. It is necessary to improve the understanding of these procedures,
taking into account their quantitative expression, in order to be able to analyze the impacts of soil erosion. In
the current study, an effort to estimate potential annual soil loss has been conducted with the use of the Revised
Universal Soil Loss Equation (RUSLE) adopted in a Geographical Information System (GIS) framework and
applied at the water reservoir’s basin of Pineios earth-filled dam, Western Greece. Data entry of the RUSLE
factors in GIS resulted to the estimation of annual soil loss equal to SE=23.39 t/ha. A significant amount of this
volume has been deposited in the dam’s water-reservoir resulting in the perennial dysfunction of the dam.
