Applying EPA SWMM hydropower and hydrodynamic wave models in analyzing the drainage network of Le Minh Xuan new urban area, Binh Chanh district, Ho Chi Minh city
Abstract
This article presents the results of a research work on the application of the EPA SWMM and hydrodynamic wave models in analyzing hydrological and hydraulic states of the drainage network in the Le Minh Xuan new urban area, Ho Chi Minh City. The researcher tested the hydraulic model to select the hydrological regime suitable for the hydro-meteorological, hydraulic, topographical, geomorphological, geological and morphological conditions of the Ho Chi Minh City area. Accordingly, the most appropriate hydraulic model was chosen as a basis for the selection of the aperture of the network culverts. The results obtained from the analysis and evaluation of the drainage network planning will help to solve the problem of flooding and high tide. From the research results, it is necessary to change the thinking and calculation method in the process of urban drainage planning in new urban areas in order to avoid repeating the scenario of what is currently taking place in urban areas.
