Based on the study of the canal's moving process, P+PR controller is used, and a simulation model of the canal is built, using MATLAB/SIMULINK. With the simulation tools of MATLAB/SIMULINK, the studies of the influence of the control parameters to the moving progress are realized conveniently and quickly, the system gets better dynamic properties. And the dynamic simulation of the canal's moving process...
The rainfall intensity-duration-frequency (idf) relationship is one of the most commonly used tools in water resources engineering. The idf relationships for traditional method are based on an at-site frequency analysis of rainfall data separately for different durations. So the researchers are focus on the distribution selection for each duration and the empirical formula to evaluate the rainfall...
Aiming at current water resources utilization situation of Nanjing, the main indicators that would have an impact on the sustainable utilization of water resources of Nanjing is analyzed in this paper. According to the contribution of the indicators to the system, three-index method is used to determine influence degree of each indicator to the evaluation object and the weight of each indicator, and...
