柳州市无资料地区中小河流水位站预警预报方法探讨

Forecast method of middle and small river level stations in data-less areas of Liuzhou City

针对柳州市新建33个中小河流水文(位)站水情预报问题,通过分析这些中小河流的特点,调查测定防洪警戒水位,建立简单的面降雨量、降雨历时、起涨水位和洪峰水位的多元回归模型,整理出预警速查表。实践证明:该方法效果较好,能较好地开展柳州市中小河流预警预报工作。

In order to determine the forecast method for the 33 new hydrological （level） stations on middle and small rivers in Liuzhou City, the characteristics of rivers were analyzed; alarm water level was investigated; simple multiple regression model was set up incorporating surface precipitation, rainfall duration, initial rising level and flood peak level; based on which the quick search sheets were made. As demonstrated by practice, this method renders good forecasting effects.
