【 摘 要 】

In Saudi Arabia the government’s land grants policy and liberal interest free loans to its public have triggered tremendous urban growth all over the country. The urbanization progress has made the available limited surface fresh water resources of the country in deep stress in terms of water quality. Countries such as Saudi Arabia, with enormous human resources cannot afford to lose the scarcely available surface fresh water resources. The current study makes an attempt to analyze the anthropogenic activities in the watershed surrounding Lake Abha through remote sensing techniques and assess its implications on water quality as found in the scientific research for lakes, streams and marine ecosystems. In this paper, a high resolution multispectral Worldview-2 (WV-2) and Landsat imageries (Landsat 1, Landsat 2, and Landsat 8) are utilized to assess the past and present land use and land cover (LULC) practices in the watershed. The image analysis revealed agricultural practices and construction activities as the two major sources of nonpoint pollution in the watershed that is directly impacting the quality of water in Lake Abha. If the local stakeholders are not mobilized to prevent the deterioration of Lake water quality, it would require huge human resources to restore the pristine condition of this lake and other water bodies in the kingdom.
