- Abstract
- Modeling river networks in plains such as deltas due to bi-directional water flows is a major challenge. An example of such a plain land is the delta region between Yangtze and Taihu Lake. Besides the Yangtze, the area is composed of several rivers, channels, tributaries and the Taihu Lake, which is one of five largest freshwater lakes in China with a total basin stretching over an area of 36.500 km2 of the plain land of the Yangtze Delta. This area is of great interest, because it is the most socially and economically developed region in China. There is natural water exchange between the Yangtze River and the local river network due to daily and seasonal tidal effects. The water from Yangtze is used for adjusting the water levels of local rivers for flood protection and navigation (i.e. securing the water transport way (Baiqugang River) between Taihu Lake and Yangtze River. Other uses of the water resources in the area include, irrigation and drainage for the agricultural areas, water for the industry and households and lastly water for maintaining the flow rate in the local river network and hence the water quality. Therefore, diverse types of artificial water conservancy projects (sluices, pumps, barriers) have been built for different purposes and specifications in the area. In order to be able to apply optimal control methods for water allocation to the multiple targets, a model based computer simulation model is required. Such a simulation model of the river system is described in this paper. It takes the hybrid behavior (i.e. water levels change continuously and some control devices such as barriers are either open or closed) of the system into consideration.
