Planning of watersheds is indispensable in terms of sustainable development and landscape management. Therefore, watershed prioritization and morphometric characterization are important to identify hydrological behavior of the basin for conducting management strategies. In this study, geospatial-statistical approach was used for identifying critical and priority sub-watersheds in the Golestan watershed. In first step, eight morphometric parameters (bifurcation ratio, drainage density, constant of channel maintenance, stream frequency, form factor, drainage texture rate, relief ratio, ruggedness number) which effect on hydrological, soil erosion and sediment transport were selected. The map of morphometric parameters using digital elevation model (DEM) were produced in ArcGIS10.2 software. In order to determine prioritization of sub-atersheds a new method based on morphometric and statistical analysis was applied. The Kendall’s tau and weighted sum analysis (WSA) methods were used for analyzing the relationship between morphometric parameters and determining their effect weights. Finally, sub-watershed prioritization index (SWPI) based on weighted linear composite (WLC) method was calculated for each sub-watersheds. For validation of the mentioned results, used of previous destructive floods location in the Golestan Watershed. The results showed that, meanwhile innovation method of prioritization, isn’t proper for all of the sub-watersheds in the study area, but the mentioned method was identified the sub-watersheds 3, 16, and 9 as the best regions for watershed management plans.
