Abstract

A hydrological model, XAJMISO is adopted from the XinAnJiang (XAJ) model and modified by transforming the parametric routing system into a non-parametric system to reduce parameters and improve performance. The pro‐ posed model replaces routing components of the XAJ model with two linear systems: surface flow and subsurface flow, including interflow and baseflow. The discharge at the basin outlet is then calculated using response functions of surface and subsurface flow, which are derived by means of a multiple input single output (MISO) system. In con‐ trast to other MISO studies, the present study defines the finite length for calculating response function coordinates based on time scales of all runoff components. The model is applied to six river basins of different data aridity indices in the United States and compared with our modified XAJ (mXAJ) model. The results reveal that the proposed model sufficiently represents the relationship between rainfall and runoff of relatively large basins and provides better and more stable performance. The proposed model also makes calibration much easier by reducing four sensitive parame‐ ters out of seven in mXAJ.

用于降雨径流分析的XAJMISO水文模型的开发

采用新安江(XAJ)水文模型XAJMISO，并将参数化路由系统转化为非参数化系统进行修正，以减少参数，提高性能。提出的模型用两个线性系统取代了XAJ模型的路由组件:地表流和地下流，包括互流和基流。然后利用多输入单输出(MISO)系统导出的地表和地下流量响应函数计算流域出口的流量。与其他MISO研究不同，本研究定义了基于所有径流组分的时间尺度计算响应函数坐标的有限长度。将该模型应用于美国6个不同数据干旱指数的河流流域，并与改进后的XAJ (mXAJ)模型进行了比较。结果表明，该模型能较好地反映较大流域降雨与径流的关系，具有较好的稳定性。所提出的模型还通过减少mXAJ中七个敏感参数中的四个敏感参数使校准变得更加容易。

期刊介绍： Hydrological Research Letters (HRL) is an international and trans-disciplinary electronic online journal published jointly by Japan Society of Hydrology and Water Resources (JSHWR), Japanese Association of Groundwater Hydrology (JAGH), Japanese Association of Hydrological Sciences (JAHS), and Japanese Society of Physical Hydrology (JSPH), aiming at rapid exchange and outgoing of information in these fields. The purpose is to disseminate original research findings and develop debates on a wide range of investigations on hydrology and water resources to researchers, students and the public. It also publishes reviews of various fields on hydrology and water resources and other information of interest to scientists to encourage communication and utilization of the published results. The editors welcome contributions from authors throughout the world. The decision on acceptance of a submitted manuscript is made by the journal editors on the basis of suitability of subject matter to the scope of the journal, originality of the contribution, potential impacts on societies and scientific merit. Manuscripts submitted to HRL may cover all aspects of hydrology and water resources, including research on physical and biological sciences, engineering, and social and political sciences from the aspects of hydrology and water resources.
