中小河流水文站预警预报方法浅析——以江村水文站为例

Warning and forecast methods for middle and small rivers hydrological stations——example for Jiangcun hydrological station

北河水文站稀少,缺少实测流量资料,针对降雨强度大、洪水暴涨暴落、预见期短等特点,以水位涨幅与相应的造峰雨建立相关关系,制定水位降雨速查表。结合中小河流外业调查成果表,为中小河流预警预报提供了参考依据。

The hydrological stations of Bei River are scarcity,which lacks observation discharge data,according to the characteristics of heavy rainfall intensity,flood surge and fall,short forecast period and so on,the correlation between the rate of increase of water level and the corresponding peak-making rain was established,establish quick-look-up table of water level and rainfall.Combined with the result table of field investigation of middle and small rivers,it provides a reference for early warning and prediction of middle and small rivers.
