Morphometric analysis and sub‐watersheds prioritisation were carried out for the Wadi Easal Basin, Jordan, which is characterised by a high topographic diversity. The total ranking method was applied to prioritise the sub‐watersheds in terms of susceptibility to flash flood. Results of morphometric analysis revealed that the study area is a fifth order drainage system with a dendritic drainage pattern and elongated shape. Prioritisation results showed that about 71% (15 out of 21 sub‐watersheds) of sub‐watersheds have high‐very high susceptibility to flooding, which forms about 64% of the total area of the basin. The main underlying morphometric parameters behind this are the high drainage density, stream frequency, high basin relief, basin slope, ruggedness number, and circulatory ratio, and the low value of basin shape. Overall, the basin has a rugged topography with steep slopes and high relief. Since the basin is ungauged, and no information about its past hydrological behaviour is present, the results of this study can be used as guidance for competent authorities to initialize flood mitigation or artificial groundwater recharge measures.

使用地理空间技术对流域进行形态计量学分析并确定流域优先级，以进行约旦瓦迪埃萨尔盆地（WEB）的洪水风险管理

对约旦的瓦迪伊萨尔盆地进行了形态分析和子流域划分的优先次序，其特征是地形多样性高。应用总分级法对子流域的洪灾敏感性进行了优先排序。形态分析结果表明，研究区域是具有树突状排水模式和细长形状的五阶排水系统。优先排序结果表明，大约71％（21个子集水区中的15个子集水区）对洪水的敏感性非常高，约占流域总面积的64％。其背后的主要形态参数是高排水密度，水流频率，高盆地浮雕，盆地坡度，崎度数和循环比以及盆地形状的低值。全面的，该盆地地势崎with，斜坡陡峭，起伏很大。由于该流域未开垦，并且没有关于其过去水文行为的信息，因此该研究结果可作为主管当局初始化防洪措施或人工补充地下水措施的指导。
