Abstract

: Simulating flow dynamics in large-scale lakes is often time-consuming. For river flood simulation, the automatic domain updating (ADU), which can effectively control the simulation domain only in and around the flooded areas, has recently been developed. It is easily implementable without any computational errors for river flood simulation; however, its applicability to lake flow simulation with pre‐ cipitation/evapotranspiration has not been investigated. This study examines the applicability of the ADU to large-scale lake flow simulation with the 2-dimensional local inertial equations (2D-LIE) taking the Tonle Sap Lake, Cambodia, as a study site. The 2D-LIE with the ADU demonstrated 2.1 times faster simulation with errors less than 5.5%. This efficiency was achieved owing to the wet/dry seasonal nature of the tropical lake and backflow from the mainstream of the Mekong River in the rainy sea‐ son, suggesting that the ADU is applicable to large-scale lake flow simulation.

域自动更新在柬埔寨洞里萨湖的应用
模拟大尺度湖泊的流动动力学常常是费时的。在河流洪水模拟中,自动域更新(ADU)是近年来发展起来的一种能够有效控制洪水区域及其周边模拟域的方法。该方法易于实现,无计算误差;然而,其在含降水/蒸散的湖流模拟中的适用性尚未得到研究。本研究以柬埔寨洞里萨湖为研究点,考察了ADU在二维局部惯性方程(2D-LIE)下大尺度湖泊流模拟中的适用性。采用ADU的2D-LIE仿真速度提高了2.1倍,误差小于5.5%。这是由于热带湖泊的干湿季节性和湄公河干流在雨季的回流特性,表明ADU适用于大尺度湖泊流量模拟。

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.
