Abstract

Water resources degradation in arid zones is one of the most important processes of desertification which is dealt with in different models of desertification by various forms. One of the main methods is F AO-UNEP method, which is one of the most complete and comprehensive methods presented in the world for eradication of desertification. But according to the analysis made on the method, it has some deficiencies, among them is neglecting special conditions of the Middle East biomes, including Iran, in cases like drought and rain, intensity and duration of rain (rain dispersion) and draw down of underground aquifer. Another method which is presented for evaluating the intensity of DESERTIFICATION PROCESS, is Iranian Classification of Desertification (ICD). In this method, due to regional reasons special attention is paid to special conditions of region's biomes. The method considers the degradation of water resources problems, such as underground water bed. Based on the analysis made on this method, it has some problems such as having small scale (1:250000), and because of that, criteria for assessment of DESERTIFICATION PROCESS are general and qualitative. According to the analysis made on the above-mentioned methods and also existing suitable criteria and factors in the area, a sample of DESERTIFICATION MODEL was given. Among the total studied areas (616.81 Km2) about 286.63 Km2 (46.46 percent) is under intensive class, and 330.18 Km2 (53.54 percent) under very intensive desertification status. As it is observed, there is no sign of weak and middle classes of desertification in the region, which indicates the amount of the WATER RESOURCES DEGRADATION in the KASHAN area.
