Grid resolution, the way in which hydraulic structures are mimicked, the model code, and the default value of the parameters are considered the main sources of prediction uncertainty. Easy to learn, PCSWMM expands with you as your confidence grows. 2D model shows real-time surface flooding where 1D model only shows flooding from. The perfect platform for exploring your best ideas PCSWMM will help improve your new water supply, drainage and green infrastructure design, floodplain delineation, sewer overflow mitigation, water quality and integrated catchment analysis, 1D-2D modeling and much, much more. Once the flood cluster areas have been identified. The analysis revealed that, for a given case, Iber 2D has the best performance in simulating the water level and inundation for flood events with 20- and 50-year return periods, respectively, followed by Flood Modeller 2D, HEC-RAS 2D, and PCSWMM 2D in terms of their performance. 2D inundation displays surface flow greater than 2 inches. The PCSWMM 2D model is used as a screening tool to identify areas of concern related to flooding. The model's performance was evaluated based on the water surface elevation and flood extent, in terms of the mean absolute difference and measure of fit. Developed a public engagement strategy Completed a desktop hydrogeological study Prepare a PCSWMM 2D model. The study area covers a 5-km reach of the Santa Bárbara River located in the Ecuadorian Andes, at 2330 masl, in Gualaceo. Environmental Assessment of the Southlands Area. This paper presents a comparative analysis of the performance of four two-dimensional hydraulic models (HEC-RAS 2D, Iber 2D, Flood Modeller 2D, and PCSWMM 2D) with respect to the generation of flood inundation maps.

Hydraulic models for the generation of flood inundation maps are not commonly applied in mountain river basins because of the difficulty in modeling the hydraulic behavior and the complex topography.
