模型参数估计是无测站流域径流模拟中需要解决的关键问题。参数区域化是应用最广泛的方法,但模型参数与流域特征间的非线性关系是参数区域化的主要障碍。本文以黄淮海流域内38个小流域为研究对象,进行了径流模拟研究,纳什效率系数(NSE)、决定系数(R2)和百分比偏差(PBIAS)的统计结果表明SWAT模型在各流域径流模拟中具有良好的性能采用6种回归模型分析SWAT模型参数与流域特征之间的定量关系,包括:线性回归方程(LR)、支持向量回归(SVR)、随机森林(RF)、K近邻(kNN)、决策树(DT)和径向基函数然后,利用其余37个供体流域构建拟合参数的回归模型,估算目标流域的模型参数,进行径流模拟。此外,本文也将基于相似性的区域化方法与基于回归分析的方法进行了对比。

Various process-based models are extensively being used to analyze and forecast catchment hydrology and water quality. However, it is always important to select the appropriate hydrological and water quality modeling tools to predict and analyze the watershed and also consider their strengths and weaknesses. Different factors such as data availability, hydrological, hydraulic, and water quality processes and their desired level of complexity are crucial for selecting a plausible modeling tool. This review is focused on suitable model selection with a focus on desired hydrological, hydraulic and water quality processes (nitrogen fate and transport in surface, subsurface and groundwater bodies) by keeping in view the typical lowland catchments with intensive agricultural land use, higher groundwater tables, and decreased retention times due to the provision of artificial drainage. In this study, four different physically based, partially and fully distributed integrated water modeling tools, SWAT (soil and water assessment tool), SWIM (soil and water integrated model), HSPF (hydrological simulation program– FORTRAN) and a combination of tools from DHI (MIKE SHE coupled with MIKE 11 and ECO Lab), have been reviewed particularly for the Tollense River catchment located in North-eastern Germany. DHI combined tools and SWAT were more suitable for simulating the desired hydrological processes, but in the case of river hydraulics and water quality, the DHI family of tools has an edge due to their integrated coupling between MIKE SHE, MIKE 11 and ECO Lab. In case of SWAT, it needs to be coupled with another tool to model the hydraulics in the Tollense River as SWAT does not include backwater effects and provision of control structures. However, both SWAT and DHI tools are more data demanding in comparison to SWIM and HSPF. For studying nitrogen fate and transport in unsaturated, saturated, and river zone, HSPF was a better model to simulate the desired nitrogen transformation and transport processes. However, for nitrogen dynamics and transformations in shallow streams, ECO Lab had an edge due its flexibility for inclusion of user-desired water quality parameters and processes. In the case of SWIM, most of the input data and governing equations are similar to SWAT but it does not include water bodies (ponds and lakes), wetlands and drainage systems. In this review, only the processes that were needed to simulate the Tollense River catchment were considered, however the resulted model selection criteria can be generalized to other lowland catchments in Australia, North-western Europe and North America with similar complexity.

采用Preissmann 4点隐式差分格式离散一维圣维南方程组,应用三级联解法求解河网水动力数学模型。基于河道-节点-河道算法的河网水质模型的求解特点,在WASP的水质模型理论基础上,建立了河网非稳态水动力综合生态水质数学模型,考虑了多个污染物变量的耦合计算、变量之间的相互转化和迁移。利用模型对4个河网算例进行验证。验证表明,水位和流量过程计算值与实测值吻合很好,各水质变量的计算值和实测值也符合较好,可见模型是合理可靠的,为河网的水质预测和管理提供了一个较为简便实用的工具。
