Analysis of Changes in the Hamun wetland Water Body during annual water inundation and land use land cover change

with the recent drought the value of water resources planning, maintenance and protection of them and also conservation of local communities has doubled. The trend of changes in water resources, particularly those that resources are limited and changed in a short time period used to manage resources. In this paper, the pattern changes of water body of Hamun wetland was investigated. Since this wetland is located in a dry area, local people are related to this valuable water resource. As a result of recent drought and limited water resources, wetlands drying period is within one year. Therefore, the process of dewatering and drying wetlands were studied during one year. In this regard, Landsat 8 OLI data were used to determine the pattern of changes in water body of Hamun wetland with short intervals. The map of water body and land cover map was prepared using the hybrid method. Validation results shows is accurate enough to produce land use land cover map in areas with a diverse land use land cover classes. The results of this study show that Hamun Hirmand support water in shorter period rather than other parts that this confirms the importance of planning to support the local population in this area .
