本文将介绍哥伦比亚河流域的洪水预报方法及水库未来的防洪控制情况。在回顾流域历史洪水的同时,也将简要介绍流域特性及开发情况。介绍水库调度方法及对预报的精度要求。水库系统的预报采用被称之为SSARR的水文计算模型。与波特兰国家气象局的河道预报中心联合运行后,该模型可用来制作短期(1～5天)和长期(5～90天)的河流洪水和水库运行预报。利用这些预报可制订单一水库或整个流域系统的防洪计划。
This article describes the flood forecasting method in the Columbia River Basin and the future flood control of the reservoir. While reviewing the historical floods in the basin, it will also briefly introduce the characteristics and development of the basin. Introduce the method of reservoir dispatching and the requirement of forecast accuracy. Reservoir systems are predicted using a hydrological calculation model called SSARR. The model can be used to make short-term (1-5 days) and long-term (5-90 days) river flood and reservoir operations forecasts, in conjunction with the Channel Forecasting Center of the Portland National Meteorological Agency. Use these forecasts to develop flood plans for a single reservoir or for an entire catchment system.
