Calibrated and validated models predicted the measured data with satisfactory accuracy and. The performance of the existing drainage system of the site is presented under different design storms with varying return periods. Personal Computer Stormwater Management Model (PCSWMM) was applied to investigate: (1) hydrological responses in the Myponga catchment as a result of land use changes and (2) the possibility of adopting Water Sensitive Urban Design (WSUD) technologies (bio-retention cells) to manage resulting floods. Therefore, this approach aided in prioritizing remediation work required to make the site drainage satisfactory. The combined model was run with different options for 2D-1D connection using side and bottom orifices and also with different orifice dimensions to simulate inlet conditions at the catchbasin grates.ĢD depiction of the dual drainage system allowed to simulate the hydraulics at the site more accurately and provided a better picture of to what depth the parking lots were inundated and how long the it took to drain the excess water. 2D cells were connected to the minor system at the existing catchbasin locations using orifices. Hydrology for the 2D system was modeled considering each 2D cell as a subcatchment in comparison to 1D model which used much larger lumped subcatchments.

Surface flow in the site (major drainage system) was modeled using PCSWMM 2D. Surface flow in the site (major drainage system) was modeled using PCSWMM 2D. Our live workshops teach you everything you need to take full advantage of the latest PCSWMM and EPA SWMM5 modeling packages. The site was modelled separately with a 1D minor system and as a dual drainage system to compare the results. This paper presents a case study of an evaluation of a frequently flooded commercial complex mainly due to the inadequacy of the minor drainage system of the site. With the increase in availability of high resolution DEMs, more accurate 2D modeling is becoming increasingly feasible. The advantage of 2D modeling over 1D modeling is because it provides a better assessment of inundation of water in a complex terrain. See our list of upcoming workshops below to learn more.Application of 2D drainage modeling has been very attractive in urban settings, especially in determining flood vulnerability of properties. It is also known by the names of udometer, pluviometer, and ombrometer. We now offer specialty workshops on specific modeling topics, including urban flooding analysis, wastewater, watershed, water distribution, groundwater, low impact development (LID) analysis, integrated 1D-2D modeling, and development impact analysis. Rain Gauge is a meteorological instrument that is used by meteorologists and hydrologists to measure the rain precipitation in a given amount of time per unit area.
