Ecological Flow Guarantee Simulation Based on Mike11 in North Canal Gate Dams Joint Regulation
At present, ensuring the ecological flow demand of the multi-water ecological target is one of the main problems faced by the water resources management of the North Canal Basin. The DHI-MIKE11 model system modeling platform is used to construct the hydrological and hydrodynamic model of river network based on the flow demand of ecologically sensitive targets. The long-term series of measured hydrological data from the 2015 and 2011 hydrological yearbooks are used to study the multi-water ecological demand protection effect of the river basin of the different scenarios. The results show that the simulated value of the hydrological station is basically the same as the measured value of the hydrology, and the combination plan of gate dams regulation + river water reduction + agricultural water-saving has a good effect. This model aims to provide the basis for the research on the river channel multi-objective ecological flow guarantee scheme, and to provide technical support for the decision-makers of the water management departments based on the multi-water flow dispatch.
