Abstract

Ground surface, at the scale of watershed, is considered as a complicated mosaic of capabilities and environmental hazards (the conflict point between society and nature), whose intensity and numerical value of profit and loss for the land use planning and sustainable development can be evaluated using different objective and subjective models. To identify the risk areas, at first, the assessment of current status of the watershed area was considered from the, physical (soil erosion, water quality), ecological (vegetation type and density) and the social- economic (income) points of view. For this purpose, the model of SWAT as well as WQI and NDVI indices were used. The economic status was studied and analyzed using questionnaires.The thresholds level of the mentioned indices was determine. To assess each parameter of erosion, the Skidmore formula was used. The quality of water was assessed using drinking water standards. To evaluate the vegetation cover, the standard of minimum average size of spot was used. The rural poverty line was also used to determine social-economic condition. The risk areas were determined by comparing the value of each parameter with their threshold levels. According to the results, 20% of the study area was above the threshold level of erosion and 15% was below the ecological threshold level. The average annual household income of the villagers was below the poverty line. The results showed that recognizing the risk areas and using risk Land-use planning approach could play a more effective role in management activities and decision making. This research can determine the direction of the essential projects in the watershed and leads to more effective executive priorities.
