Critical depth of water is an important hydraulic parameter in open channel hydraulics, which is a key sign of distinguishing the flow state of water in open channel. The traditional methods for calculating critical water depth of open channel with trapezoidal section include the trial-and-error method, the approximate solution and the iteration method, which own shortcomings of large amount of calculation...
Urban flood control layout, based on which urban flood control engineering projects are constructed, will be synthetically evaluated taking into consideration the social, political, economic, environmental and technical factors involved in different levels. Furthermore, a hierarchical structure model for urban flood control layout is presented in this paper. Then a grey-AHP model is proposed based...
