Abstract

The case studies concerning the rate of soil movement by wind in flat areas in central parts of Iran show that soil erosion in these areas is more than water erosion in mountainous areas of the some parts. The sand dune fixation and DESERTIFICATION/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> COMBAT DESERTIFICATION office is responsible for combating WIND EROSION and the reduction of DESERTIFICATION effects. As a result of some requests from desert provinces some proposals have been approved and also some projects have been performed but, in fact, due to financial limitations in our country, they are not perfectly practical. The studies which was done in desert areas show that the best time for combating WIND EROSION is the off - take stage, because it involves lower expense and more success. However, in some sedimentation areas, it is necessary to perform some projects to reduce the losses resulting from erosion. Therefore, through a national program the office took action to-recognize and classify CRITICAL POINTS and loss rate to estimate. In this article, Tehran province eotimate only is under consideration. To recognize CRITICAL POINTS of WIND EROSION in Tehran province, the source finding method of SAND DUNES has been used (Ekhtesasie-Ahmadi, 1374). In this method, the effective factors in finding these points are considered and through a systematic process, off -take, carrying and sedimentation areas are determined. Through gathering some local information and questionnaires, considering morphological studies on wind deposition, and also studying the eroding wind regime effective on WIND EROSION, the sand movement direction is determined. Through some researches, it was specified that from among 12 towns of Tehran province which covered 1, 890, 900 hectares, only 101, 725 hectares are considered as CRITICAL POINTS. These points are located in Mahdasht region in Karaj town, NajmAbad region in Savojbolagh town and Abardej region in Varamin town. According to intensity of loss rate, Mahdasht is placed at the first rank and Abardej and NajmAbad are placed on the second rank.
