Application of a single‐event hydrological model to the arid watershed of Wadi El‐maghayer, Jordan

Abstract

Arid and semi‐arid lands suffer from scarce water conditions. Rainfall occurs over brief intervals producing short intensive floods. Due to the complete absence of gauge stations in the local wadis reliable watershed analysis is necessary in irrigation planning and project design in this environment. This paper presents a wadi network analysis for El‐Maghayer dry watershed near Amman, Jordan. The analysis of this watershed is based on hydrologic routeing techniques relative to arid or semi‐arid land and, taking into account major loss rate components of land depression, evaporation and base flow, runoff hydrographs are routed by the wadi storage method.
