为加深对科罗拉多州洪水的水文气象的理解,进行了河川径流、降雨和古水文学的多学科研究。常用的洪水频率分析方法不足以说明科罗拉多州山麓丘陵和山区的洪水水文现象。其洪峰流量是由山区高海拔融雪和低海拔降雨引起的。在海拔2300米以上(这个海拔高度在一些流域是较低的),是融雪而不是降雨影响洪水。在海拔2300米以下,大暴雨产生的洪水是常见的。以古洪水资料为限据的区域洪水频率法研究表明,1976年发生的大汤普森河洪水约为10000年一遇。这一研究的方法和结果,在可减小水工建筑物设计的不确定度方面可能是有用的。例如大汤普森河流域奥林匹斯坝溢洪道的设计,而且也可应用于其它的水文研究。
In order to deepen the understanding of hydrological and meteorological phenomena in Colorado floods, multidisciplinary research on river runoff, rainfall and palaeohydrology has been conducted. Commonly used methods of flood frequency analysis are not sufficient to illustrate the flood hydrology in the foothills and mountains of Colorado. Its peak flow is caused by high mountain snowmelt and low rainfall. Above 2,300 meters above sea level (this altitude is lower in some basins), snowmelt rather than rainfall affects the flood. Floods caused by heavy rain are common at altitudes below 2,300 meters. The study of regional flood frequency based on ancient flood data shows that the Great Thompson River flood in 1976 was about 10,000 years. The methods and results of this study may be useful in reducing the uncertainty of the design of hydraulic structures. Such as the design of the Olympus Dam spillway in the Great Thompson River, but also for other hydrological studies.
