摘要日本陡坡山区占河川流域的70%。为了预测河流流量的山区集水区，许多研究应用分布式水文模型的基础上，运动波近似与表面和地下流组件（DHM-KWSS）。这些模型重现了在日本观测到的河流流量集水区，但是，DHM-KWSS集水区与不同的地理和气候条件的适用性还没有得到充分的研究。本研究应用DHM-KWSS两个流域，有不同的气候条件下，在日本的流域，以检查DHM-KWSS模型结构的可移植性。我们的研究结果表明，DHM-KWSS模型结构解释了湿润河流流域的流态以及干旱流域的大洪水事件，但是，它无法解释干旱流域案例研究的长期流态。
Abstract Steep mountainous areas account for 70% of all river catchments in Japan. To predict river discharge for the mountainous catchments, many studies have applied distributed hydrological models based on a kinematic wave approximation with surface and subsurface flow components (DHM-KWSS). These models reproduce observed river discharge of catchments in Japan well; however, the applicability of a DHM-KWSS to catchments with different geographical and climatic conditions has not been sufficiently examined. This research applied a DHM-KWSS to two river basins that have different climatic conditions from basins in Japan to examine the transferability of the DHM-KWSS model structure. Our results show that the DHM-KWSS model structure explained flow regimes for a wet river basin as well as a large flood event in an arid basin; however, it was unable to explain long-term flow regimes for the arid basin case study.
