摘要
流域和河流属于复杂巨系统,通过水文-水动力耦合的方式可建立起2者之间的水力联系,同时弥补了模型各自的不足,提高了水文预报的精度。系统概述了水文-水动力耦合模型在国内外的应用情况,归纳总结了耦合模型的基本理论框架以及模型耦合与评估的一般方法,并从学科发展与应用角度提出了耦合模型的应用难点与发展趋势,以期为流域河流系统的精细化水文模拟与预报研究提供一定的借鉴和参考。
Watersheds and rivers are complex giant systems, hydrological-hydrodynamic coupling can be used to establish the hydraulic links between them, and make up for the shortcomings of the model and improve the accuracy of hydrological forecast. This paper outlines the application of hydrological-hydrodynamic coupling model systematically at home and abroad, summarizes the basic theoretical framework of the coupling model and the general method of model coupling and evaluation, and puts forward the difficulties and development trend of the coupling model from the perspective of discipline development and application9 with a view to the river basin system of fine hydrological simulation and forecast.
