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

这个由爱荷华大学的罗伯特·埃特玛博士和水资源研究中心的o·斯塔罗索斯基博士共同发起的美国-匈牙利研究项目的主要目标是研究冰雪覆盖的河流中水流和沉积物运输的机制。研究人员将采用实验室和实地研究以及数学模型。他们打算利用在匈牙利对多瑙河和蒂萨河的四个断面进行的实地研究，作为获得实地个案研究数据的手段，以评价涉及美国冰覆盖河流的类似水资源开发。数学模型将直接耦合水流、河床几何和泥沙输运过程。结果将显著提高我们使用计算水力学作为有效模拟冰覆盖冲积河道流动的工程方法和工具的能力。这个项目是流动的，微粒和液压系统工程实现了推进科学知识的计划目标，使美国和匈牙利的领先研究人员能够在平等的基础上，在共同感兴趣和有能力的基础科学研究领域结合互补的努力和能力。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.
