摘要

由于计算机和信息技术的快速发展，计算机建模已成为流域研究和管理实践的重要工具。斯坦福流域模型(Stanford Watershed Model, SWM)是一种基于物理的综合流域模型，可以通过考虑地表水和地下水之间的相互作用来模拟水流/运河网络以及地表径流、互流和蒸发。本研究的目的是应用SWM估算年平均降雨量约为300 mm/年，集水区面积为1800 km的Wadi Wala河流半干旱区的降雨-径流关系。SWM已被广泛接受为一种工具来合成每小时或每天的连续水流图。采用敏感性分析和试错调整技术对模型参数数量进行优化。比较Wala流域的估算和实测地表径流表明，该模型在预测类似流域的年降雨量总地表径流方面相当有效。

Modeling of Rainfall-Runoff Relationship in Semi - Arid Watershed in the Central Region of Jordan

As a result of quick progression in computer and information technologies, computer modeling has become a vital tool in watershed research and management practices. Stanford Watershed Model (SWM) is an integrated physically based Watershed model that can be used to simulate water flow stream/canal network and overland runoff, interflow and evaporation by considering the interaction between surface water and subsurface water. The objective of this study is to apply the SWM in order to estimate the rainfall-runoff relationship for Wadi Wala streamflow semi arid area with an average annual rainfall of about 300 mm/yr and a catchment area of 1800 km. SWM has been widely accepted as a tool to synthesize a continuous hydrograph of hourly or daily streamflow. Sensitivity analysis, as well as trial and error adjustment techniques were used for the optimization of the number of parameters of the model. Comparing estimated and measured surface runoff for Wala valley indicated that the model is considerably efficient in predicting the total annual surface runoff from rainfall for similar watersheds.
