仅依据汇流系统出流资料确定Nash模型参数的研究

Determining Parameters of Nash Model only According to Outflow Data of the Concentration Flow System

摘要: 从理论上建立缺乏水文资料或水文资料不配套情况下的流域汇流计算方法是水文学家长期追求的目标.在分析半个世纪以来这方面主要研究成就的基础上,认为确定流域汇流模型参数的途径可划分为三类.对其中仅根据汇流系统出流资料确定Nash模型参数的理论公式和实施步骤作了详细探索,取得了初步成果,指出了进一步研究的方向.建议的方法对我国干旱、半干旱内陆边远不易布设足够雨量站点的地区的水文计算和预报工作具有实际意义.

Abstract: Three approaches for determining parameters of the watershed concentration flow models are suggested by using hydrological or geographical data. The theory and method for determining parameters of the Naah model, which is only according to outflow data of the concentration Bow system, are discussed in detail, and some examples are also given in this paper.
