变动分流比边界在赣江下游河网模型中的应用

Application of variational distributary rate boundary in river-net model of lower reach of Ganjiang River

由于数据资料的局限,分流比信息往往作为河网模型边界条件的一种给定方法。文章针对分流节点增加了河网模型相应的处理功能。修改后的模型能够很好地表征分流信息,将其应用到赣江下游的河网模型计算中,获得了和实测数据一致的结果。

On account of the limited basic data, distributary rate information is often used to determine the boundary condition of river-net model. In this paper, the processing ability of the river-net model is improved with distributary points. The improved model can simulate the distributary information correctly, and the results of its application in the river-net model of the lower reach of the Ganjiang River is consistent with the observed ones.
