U.S.-Hungary Research on Flow in Ice-Covered Alluvial Channels

这项由爱荷华大学的Robert Ettema博士和水资源研究中心的O.Starosolszky博士合作的美国-匈牙利研究项目的主要目标是研究冰盖河流中的水流和泥沙输送机制。研究人员将采用实验室和实地研究以及数学建模。他们打算利用匈牙利对多瑙河和蒂萨河四个横断面的实地研究，作为评估涉及美国冰河的类似水资源开发的案例研究实地数据的一种手段。数学模型将直接耦合水流、河床几何形状和泥沙输送过程。研究结果将显著提高我们使用计算水力学作为有效模拟冰盖冲积河道水流的工程方法和工具的能力。这个流体、颗粒和液压系统工程项目通过使美国和匈牙利的顶尖研究人员能够在平等、互惠的基础上，在基础科学研究领域共同感兴趣和能力强的领域结合互补的努力和能力，实现了促进科学知识的计划目标，和互惠互利。

The primary objective of this U.S.-Hungary research project between Dr. Robert Ettema of the University of Iowa and Dr. O. Starosolszky of the Research Center for Water Resources is to examine the mechanics of flow and sediment transport in ice-covered rivers. The researchers will employ laboratory and field studies as well as mathematical modeling. They intend to draw upon field studies in Hungary at four cross sections of the Danube and Tisza Rivers as a means of obtaining case-study field data for evaluating similar water-resources developments involving U.S. ice-covered rivers. The mathematical models will directly couple flow, bedform geometry and sediment transport processes. Results should significantly improve our ability to use computational hydraulics as an engineering methodology and tool for effectively simulating flow through ice-covered alluvial channels. This project in fluid, particulate and hydraulic system engineering fulfills the program objective of advancing scientific knowledge by enabling leading researchers in the United States and Hungary to combine complementary efforts and capabilities in areas of strong mutual interest and competence in the field of basic scientific research on the basis of equality, reciprocity, and mutuality of benefit.
