Research on Unsteady Flow of River Network Programming Based on Data Driving Mechanism
LI Guang-chi · Water Resources and Power · 2012
Based on analysis of river network flow characteristics,an object oriented universal model is established to calculate unsteady flow of river network.According to data driving mechanism and relational data model,the data schemes for various data are established,which makes it possible to share the same observed data in different simulation models.Accordingly,a visual program integrated with open-source GIS software is designed on the basis of hierarchical framework.Finally,the program is applied to simulate the flow in the reach from Datong to Zhenjiang on the Yangtze River.The results show that the program can compare alternative projects and meet the requirements of practicability and general utilization.
