Abstract

The present study aimed to locate the areas prone to flood spreading in order to manage surface water resources. Therefore, the information layers of slope, land capability, quaternary units, alluvium thickness and land-use were applied in GIS environment. In this regard, the layers were rated in proportion to their effect on feeding of aquifer. Then, according to the Multi Class Maps model, the weighted layers were combined and the map of areas prone to flood spreading in with four very suitable, suitable, somewhat suitable and unsuitable classes was prepared. The results showed that using this method, large areas can be studied using GIS and remote sensing. The total area of the region studied is 1 280 762 hectares of which 58 524 ha are in a very suitable class, 132 673 ha in suitable class, 245 584 ha in somewhat suitable class and 843 978 ha in unsuitable class. The factors of slope, alluvium thickness, quaternary units and land capability are the most important factors, respectively.

使用GIS易洪泛滥的地区的位置（伊朗伊斯兰共和国）

摘要

本研究旨在确定容易泛滥的地区，以管理地表水资源。因此，在GIS环境中应用了坡度，土地承载力，第四纪单位，冲积层厚度和土地利用等信息层。在这方面，各层按其对含水层进料的影响成比例地定级。然后，根据“多类地图”模型，将加权图层组合在一起，并准备了易于洪水泛滥的区域地图，分为四个非常合适，合适，有些合适和不合适的等级。结果表明，使用这种方法可以使用GIS和遥感技术研究大面积区域。研究区域的总面积为1 280 762公顷，其中58 524公顷属于非常合适的等级，132 673公顷属于合适的等级，245 584公顷属于适当等级，843 978公顷属于不合适等级。最重要的因素是坡度，冲积层厚度，第四纪单位和土地承载力。
