Abstract:

This paper sets up precipitation runoff models in plain river networks area to translate the spatial distribution of rainfall with different ways of open river network and polygonal river network. It also sets up method of calculation by given dynamic rainwater gathering, flow throughput and polygonal feature of river channel that leads to realization of runoff spatial distribution of plain river networks. By using the method it simulats the most and average rainwater gathering area of Changzhou and Wuxi sections of Sunan canal and the runoff spatial distribution of the typical polygonal feature of plain river networks which enclosed by Xibei canal, Wangyu river, Yangjiantang river and Yanyang river. It gets the more actual condition simulated result of runoff spatial distribution in polygonal river network by giver the flow throughput and polygonal feature of river channel. And also it gets that the dynamic rainwater gathering simulation technique not only can use in open river network, the single river and the macro-control of drainage runoff but also can provide a basis of distribution of waste load.

Keywords:

Plain river networks, dynamic rainwater-collection, flow throughput, polygonal feature of river channel, spatial distribution of runoff yield
