摘要
在全面综述分析国内外文献的基础上 ,提出和建立了一个基于DEM的分布式流域水文物理模型 ,并用来模拟小流域的降雨径流时空变化过程 ,得到了较好的模拟结果 .论文分为模型结构和应用检验两部分 .本文论述模型结构和数值解法 ,详细分析植物截留 ,蒸散发 ,融雪 ,下渗 。
Based on the current state_of_art of rainfall runoff models, a DEM and physically based distributed hydrological model is proposed and developed. The paper consists of two parts, model structure and application. The model structure and mathematical equation as well as numerical procedures are described. The hydrophysical process, such as interception, evapotranspiration, snowmelt, infiltration, surface runoff and underflow, are discussed in detail.
