تطبيق نموذج RUSLE لتقدير إنجراف التربة في قطاع غزة-فلسطين باستخدام نظم المعلومات الجغرافية

الملخص EN

The study aimed to calculate the amount of soil erosion in Gaza Strip and identify areas of most exposed to soil erosion risk to take appropriate measures.

The study used a Digital Elevation Model of the type of DSM from the Japanese satellite ALSO with a resolution of 30 metre, a satellite image of the satellite Landsat 8 taken on 29/10/2018, and GIS techniques in the calculation of the elements of the Revised Universal Soil Loss Equation (RUSLE).

The results showed that the soil drift values in the study area range between 0.11-504 tons/ha/year, an average of 4.7 tons/ha/year, and that the total amount of soil in the Gaza Strip is 18,66658 tons/year, and the areas at risk of a very high drift account for 10% of the Gaza Strip, and are concentrated in Gaza City and the valleys (Gaza Valley, Beit Hanoun Valley, Salqa Valley) and In the coastal area of the cliffs, GIS is an effective and rapid tool in studying the problem of soil erosion.

The study recommended using the RUSLE model to integrate with GIS and RS techniques in estimating the risk of soil erosion, and that appropriate measures should be taken to prevent soil erosion in the study area.
