عنوان فارسی Flood Probability Mapping and Zoning in the Tanguiyeh Basin, SirjanAbstract
چکیده فارسی مقاله Flooding is recognized as one of the most complex and destructive natural hazards, causing more annual damage globally than any other natural disaster. Flood hazard zoning maps are crucial tools for identifying vulnerable and at-risk areas, thereby facilitating the implementation of effective management strategies. This study aimed to map flood probability within the Tanguiyeh Basin. To achieve this, key variables including vegetation cover, land use, drainage network density, distance from the drainage network, lithology, rainfall, topography, and slope were identified from various sources and integrated as informational layers into ArcGIS. Subsequently, a panel of 30 experts and flood hazard specialists weighted these variables in two rounds. The flood hazard zoning map of the Tanguiyeh Basin was then generated by integrating these weighted layers. The results indicate that areas with very low flood probability constitute 1.36% (15.48 km²) of the basin, low probability areas cover 8.79% (100.064 km²), medium probability areas represent 67.47% (767.82 km²), high probability areas comprise 22.37% (254.553 km²), and very high probability areas account for 0.01% (0.121 km²). Furthermore, the northern, eastern, and southern sections of the region show higher flood potential, primarily attributed to increased rainfall, lower permeability, and steeper slopes.
