水冰差与流量相关曲线的创建及应用

Establishment and application of correlation curve with water and ice difference and discharge

水位与流量关系曲线在水文资料整编中应用广泛,但冰期尤其是具有很长封冻期的河流,还没有一种能像水位与流量关系曲线那样的定线推流方法。因为冰期水位、流量关系紊乱、不成规律,所以一直以来未能发现一种很好的相关方法。本文所提出的水冰差这一新概念,并且与流量建立相关关系,创建如同畅流期水位与流量那样的关系曲线。通过定线推流验证,完全可以实现冰期水文资料以相关曲线法进行定线整编。

The water level and discharge correlation curve is widely used in the hydrologic data compilation,but there is not yet a calculation method like water level and discharge correlation curve to determinate the discharge in ice period,especially in rivers with long freezing period.Because the ice age water level and flow correlation curve are disorder and irregular,it is impossible to find a good relationship all the time.The paper proposes a new concept of water and ice difference,establishes a relationship with flow and creates a correlation curve like water level and flow during the flow period.Through the verification of the flow calculation,it is possible to compile the hydrological data with the relationship curve method in the ice age.
