摘要：
High flood occurrences with large environmental damages have a growing trend in Iran. Dynamic movements of water during a flood cause different environmental damages in geographical areas with different characteristics such as topographic conditions. In general, environmental effects and damages caused by a flood in an area can be investigated from different points of view. The current essay is aiming at detecting environmental effects of flood occurrences in Halilrood catchment area of Kerman province in Iran using flood zone-mapping techniques. The intended flood zone map was introduced in four steps. Steps 1–3 pave the way to calculate and estimate flood zone map in the understudy area while step 4 determines the estimation of environmental effects of flood occurrence. Based on our studies, wide range of accuracy for estimating the environmental effects of flood occurrence was introduced by using flood zone-mapping techniques. Moreover, it was identified that the existence of Jiroft dam in the study area can decrease flood zone from 260 to 225 ha and also it can decrease 20 % of flood peak intensity. As a result, 14 % of flood zone in the study area can be saved environmentally.
