春汛

以初冰期流量为因子预报春汛来水量

Taking discharge in initial ice period as factor to forecast spring flood

平原宽浅或流域内含大面积沼泽地的河流，春汛来水量主要受春季融冰影响，即与封冻时流量大小相关。

For the plain wide and shallow river or the river in its basin containing a large area marshland , the melting ice in the spring influences the inflow of spring flood or correlates with the discharge at freezing period .

对水库春汛的防洪风险进行了定性分析。

The flood control risk in spring was analyzed by the qualitative analysis .

1994一1997年的渔业统计显示：夏、秋汛渔获量高于冬、春汛。

From the statistics of pelagic fishery during 1994-1997 . The yield in Summer and autumn is higher than that in winter and spring .

多年的研究排除了观测误差、坝基变形、碱骨料反应及春汛等因素的影响，认为是由冻胀引起的。

This was attributed to the influence of frost action in the outer exposed area of the dam after excluding many factors such as measurement errors , foundation movement , alkaline aggregate reaction and spring floods .

其预报准确率春汛单位日渔获量为83.7598.16%，平均为91.27%，春汛总渔获量为66.9297.37%，平均为87.9%；

Their forecast accurate rates are : The spring , the catch of day of unit ranged from 83.75 % to 98.16 % , average 91.27 % , the total catch ranged from 66.92 % - 97.37 % , average 87.90 % .
