The Impact of Rochester Storm Sewers on the Water Quality of the Lower Genesee River: A Modeling Approach Using PCSWMM
… network (ROCSWMM) using hydrologic modeling tool PCSWMM (Storm Water Management Model). Model-predicted flows, total phosphorus (TP) loads, and total suspended solid (TSS) loads to the Genesee River for 2012 were 19,197,116 m3, 2,277 kg P, and 625,694 kg, respectively. More than 50% of the total …

Les impacts des changements climatiques sur le réseau de drainage: le cas de la portion urbanisée du bassin versant de Mill Creek, Nouveau-Brunswick
… calibré et validé à l’aide du logiciel PCSWMM afin d’analyser, par simulation numérique, les effets probables des changements climatiques et d’occupation du sol sur le débit superficiel du réseau de drainage urbain de ce bassin versant. En outre, une modélisation 2D a également été …

Analysing peak flow attenuation in an urban wetland
… wetland adjacent to an urban river using a 2D PCSWMM hydrodynamic model. Research is focused on illustrating the attenuation capacity of this wetland. The model ran historic flow data to determine the attenuation capacity and to measure peak flow reduction. While the reduction is not sufficient …

Quantifying stormwater pollutants and the efficacy of sustainable drainage systems on the R300 highway, Cape Town
… R300 rainfall-runoff response was modelled in PCSWMM to evaluate the performance of SuDS such as infiltration trenches, bioretention areas and swales for managing highway runoff in terms of quantity and quality. The modelling exercise showed SuDS to be a viable means to attain the City of Cape …

The viability of transforming stormwater detention ponds into infiltration ponds on the Cape Flats, South Africa
… A computational hydraulic simulation using the PCSWMM Professional (version 7.5) software revealed that retrofitting a detention pond to improve infiltration led to a MAR increase of 290%. Laboratory studies showed that stormwater from the CoCT, which was of poor quality, could be treated by …

Managing the Water Quality of the Zandvlei Estuary using Sustainable Drainage Systems in the Diep Catchment
… implementing SuDS in Zandvlei's Diep Catchment. PCSWMM, a modelling software developed by Computational Hydraulics International (CHI), was used to develop seven models. Included was an As-is model, developed, calibrated and verified to represent the Diep Catchment in its current state, a …

Reduction of pollution levels in the Chatty River through Sustainable Drainage Systems: A case study of the Bethelsdorp River sub-catchment
… and hydrological models were constructed in PCSWMM, a stormwater management modelling software developed by Computational Hydraulics International (CHI) using the USEPA SWMM model as the ‘engine'. Both the Chatty River Catchment as a whole as well as the Bethelsdorp River sub-catchment, …

Managing nutrient flows into the Zandvlei Estuary, Cape Town using Sustainable Drainage Systems (SuDS)
… Keysers and Westlake River sub-catchments. The PCSWMM software package developed by CHI, which uses the SWMM engine developed by USEPA, was employed. Data regarding historical rainfall, land use, stream flow, surface cover, soil types, geology and historical temperatures were used to construct …

Quantification of climate change impacts on urban catchment hydrology and water sensitive design devices
… in future. The flow time series generated by PCSWMM indicated that peak flow (Q.001) is increased by 370% under RCP 4.5 and low flow (Q95) is increased by 40%. Likewise, most of the IHA parameters show a significant variation in the 2050s and 2090s indicating a severe impact on the ecological …

The performance of SUDS ponds in Eastern Scotland
… of the monitored catchments were modelled in PCSWMM 2002 (Personal Computer Storm Water Management Model), and the existing SUDS layouts were compared to alternatives. The performance of each layout was evaluated for its predicted performance in peak flow and volume reduction. For this, a …

Resilience of Water Sensitive Design Assets in Urban Environments Against Flooding and Climate Change
Urban sprawl has led to the conversion of previously natural, pervious land into impervious surfaces. Consequently, this increase in impervious areas has elevated the risk of urban flooding. Water Sensitive Design (WSD) assets are engineered green infrastructure implemented in new urban …

NATURE-BASED SOLUTIONS FOR FLOOD RISK MITIGATION: MAPPING AND HYDROLOGICAL MODELING IN AN UNDER-RESOURCED URBAN AREA ON THE MISSISSIPPI GULF COAST
<p>Flooding is the most frequent and costly disaster in the United States, affecting people disproportionately based on environmental, societal, and economic limitations. Through stakeholder engagement, open-access research, and nature-based solutions (NBS), ecology and hydrology can be bridged …
