Utilizing Soil Erosion Modeling and GIS Technologies to Develop Future Soil and Water Conservation Strategies

Abstract

Drought and soil erosion stand as predominant drivers of land degradation within arid regions. The infrequent occurrence of rainfall events and subsequent flash floods significantly diminish agri-food productivity and exacerbate soil erosion rates. Thus, employing a modeling approach becomes imperative for forecasting flash floods and soil losses. The aim of this book chapter is to provide an introduction to soil erosion modeling and to delve into the performance evaluation of the kinematic runoff and erosion model (KINEROS2) through a case study conducted in Egypt. The model utilizes satellite imagery of digital elevation maps, soil maps, and annual weather datasets. Runoff discharge data observed at the outlet of the watershed is integrated into the model. In conclusion, it is strongly advised to integrate satellite imagery with the KINEROS2 model, a step that promises significant benefits in detecting environmental changes and understanding their impact on the watershed.
