As these 2D models are recently been available so 1D will also be used in the initial stage to check the accuracy of 2D models. The project is to work on the new 2D hydraulic/hydrological modeling of urban catchments using PCSWMM 2D. This software overcomes the limitation in the 1D model such as flow direction and comes with various new features for better understanding and accuracy. These are used for flood modeling and are helping to plan and design the strategies for flood management. PCSWMM 2D is a software developed by EPA in 2011 integrating the previous 1D modeling software. This effect can be reduced by using the solution achieved by modeling and preparing in advance for the predicted effects of the floods. According to Chen, Djordjevic, Leandro, and Savic (2007), the effects of floods in developed areas are also high as it is directly related to the high number of people living and working in these urban areas. The rapid trend towards urbanization and climate change are the key factors of the increase in the frequency of floods. In recent years most of the natural disasters around the world have been the result of major floods, which have affected over half of the world’s population (UNISDR, 2014). IntroductionĪccording to Awbi (1989), flooding is one of the major emerging concerns around the globe. The PCSWMM tool was evaluated for use in practical situations and coherent results were established, showing that the minimum requirements were achieved to model the flow of floodwater in complex urban areas with several nodes and interconnected cells. There is an excellent agreement between the 1D and 2D models based on the modeling results using the PCSWMM software, which is a new but effective tool for modeling. The results show that the 2D model was created by use of interconnected nodes and cells and links which represent the physical features of the area being modeled. In only 3 hours we’ll deliver a custom 1d – 2d Flood Modeling Using PCSWMM essay written 100% from scratch Get help The modeling was done using the PCSWMM software with the objectives of developing the 2D model from the 1D model. This study was conducted using artificial modeling, which was based on an abstract representation of real-world flood events in the Taco River and the flow of water in real urban areas.
The main weaknesses of the 1D model are that they are unsuitable for urban and intricate systems modeling, leading to the creation of the 2D model.
1D models, which have been used for flood modeling have shown significant weaknesses, which prompted research into 2D modeling of floods. This study was conducted to develop a 2D model from the 1D model.
