赣江下游河段设计最低通航水位计算方法

Computation of designed lowest navigable stage in lower reaches of Ganjiang River

用保证率频率法计算赣江下游河段设计最小通航流量,再从近几年枯水期水位流量关系曲线上查得对应于该流量的水位,即为设计最低通航水位.用该方法计算的设计水位更符合河道的实际情况.

The designed minimum navigable discharges in the lower reaches of Ganjiang River are calculated by use of guarantee rate and frequency curves method, and the corresponding stages, namely the designed lowest navigable stages, are obtained from the stagedischarge relation curves in lowflow periods in recent years. Calculation results show that the design stages are more conformable to the actual waterway stages.
