相应水位法在水文预报中的应用

相应水位法是目前洪水作业预报中应用较为广泛的一种简便水文预报方法。它根据河道洪水波运动原理,洪水波上同一位相点（如起涨点、洪峰、波谷）通过河段上下断面时表现出的水位,彼此称相应水位,建立相应水位经验关系,由上断面现时水位预报下断面未来时刻水位的河道洪水预报方法。主要通过对牡丹江长汀子水文站与牡丹江水文站建立洪峰水位相关关系,实现对牡丹江水文站洪峰水位的预报,为牡丹江市防汛调度提供及时的水文信息。

Application of Corresponding Water Level Method in Hydrological Forecast

The corresponding water level method is a simple hydrological forecast method applied widely in current flood forecast.Based on the theory of flood wave motion in river course,the same phase point on the flood wave(such as flood rising point,peak and wave valley) will show a real time water level on the upper and lower river sections,calling the water level for corresponding water level each other.The corresponding water level experiential relation can be established,then forecast the future water level of lower section from current water level of upper section in river course.The flood peak water level forecast in Mudanjiang Hydrological Station is realized by constituting relevant relations between Mudanjiang Changtingzi Hydrological Station and Mudanjiang Hydrological Station in this study and it provides real-time hydrological information for Mudanjiang River flood control management.
