## Dynamic boundary condition of unsteady flow in open canal with automatic constant upstream level control

Wang Changde;Wei Zhilin;Zhang Liwei(Wuhan University of Hydraulic Electric&Engineering)
In this paper,the governing process of the AMIL gate is firstly analyzed andthen the mathematical model of the operation of upstream constant level gate is given. Regarding gate movement as dynamic boundary condition of the canal flow,the mathematical model of the dynamic response of the canal with automatic upstream constant level control is established. Appling Laplace transform, Z-transform and inverse Z-transform to the model of dynamic response of the gate, a difference equation, which describes the gate movement affected by water level in canal, is yielded. Regarding the difference equation and one-dimentional calculating model of unsteady flow in open canal as boundary conditions each other andusing uncoupled method, the equations can be solved so that we can predict thedynamic response of the gate as well as canal, thus improve their designs and managements.
