Abstract

Wadi Auranah is one of the potential wadis located on the western shield (Hijaz escarpment) of Saudi Arabia. A spatio-temporal change assessment of the wadi was conducted with the help of landsat data. The results of the spectral analysis and NDVI for vegetation changes assessment reveals a continuous increasing trend of land cover biomass in specific parts of the wadi. Geological review by enhancing geological map and field assessment of the study area showed this trend. About 73 km2 of vegetation land cover has been created in the last 20 years. Treated wastewater is the main source of water supply that is used for afforestation and cultivation purpose.
