To minimize the damage resulting from oil spill accidents, it is necessary to respond quickly with an appropriate strategy. Accurately forecasting the behavior of the spilled oil is crucial for a successful recovery operation and protection of marine resources. Therefore, the numerical modeling and simulation of the spilled oil at sea plays an important role in the oil spill response and contingency...
Marine water quality model is complicated because of its multi-parameter and multi-response characteristic. In this paper, a new method based on data-driven model (DDM) is developed to retrieve the value of model parameters for model calibration. All training data are calculated by numerical water quality model from results of multi-parameter matching design cases. The basic idea is to find out the...
The lack of knowledge about water flow and particle behavior of the grit chamber with rotational flow remains a significant difficulty for the design of these work in sandstone wastewater of hydropower station. In the paper, Eulerian-Lagrangian multi-phase model is set up. The grit chamber with rotational flow in the powerhouse, which is located in southwest of China, is as a case. Velocity field...
The quantity of available water resources have been recognized as limiting factors in development of most of the arid regions. Therefore, sustainable use of water resources is key problem for development of these areas. In the present paper, Hetao irrigation district, one of the largest irrigation districts in the Yellow River basin, is selected as the research area. The sustainable utilization coupled...
It applies hydrodynamic Model to simulate COD of sewage around Xiaoyangkou, Rudong City, Jiangsu Province in this paper. Curvilinear orthogonal grid is used in interesting area, and hydrodynamics and water quality model are used to the current velocity field and tidal level field both on case of the spring and the neap tide. The computational results are compared with measured field data around drain...
