When I changed this and runt, my model again, the continuity error went from ~ 3% to 7%. Up to hear nothing is out of extraordinary, however, at first, I set the outlet offset of the upstream pipes to the pumping stations to 0 m as no information was known in advance.My new model, same conditions as above, includes the offset of the upstream pipes for each pumping station. I have likewise set up the calibration for wet conditions and results are fair enough for both cases. I am working with PCSWMM (I apologize as I am not using SWMM per se) to set up my DWFs and flow patterns, run and calibrate the model (I have 7 points for calibration purposes). The system is roughly composed of 100 km of pipes, 13 lifting pump stations (34 pumps) and 1,600 junctions. Thank you all in advance!I am currently working at simulating the complete sewer system of a municipality.

Hi all,I am reaching out hoping someone can enlighten me with two questions. However, green roof technology also was the least favored option for the public and stakeholder acceptance will impact SUDS implementation.Continuity error related to pumping and inclusion of on-site pumping measurements to simulations The household interviews revealed the majority of people preferred pervious pavement to the other SUDS options and the least preferred option was green roof technology.Д¬onclusion: Considering the combination of water quantity and water quality controls, it seems that green roof technology was the best performer for this area of Ho Chi Minh City, followed by urban green space, pervious pavement and rainwater harvesting. Regarding environmental improvements, as represented by reduction in total suspended solids load, urban green space was best with 20% of the solids load removed compared to the base case scenario, followed by green roofs, pervious pavement, and rainwater harvesting.

With respect to SUDS performance, green roofs were best at reducing peak runoff (22% reduction), followed by pervious pavement, urban green space, and rainwater harvesting systems. Results: PCSWMM results showed that inundation from intense rainfall could be reduced with proper land-use control, specifically by maintaining imperviousness at 65% or less of the surface area. Thirteen SUDS and urban build-out scenarios were simulated under 6 design storm conditions. Methodology: A combination of the Stormwater Management Model (PCSWMM) and interviews with 140 households was used to assess the efficacy and acceptability of four of the most popular SUDS: Rainwater harvesting, green roofs, urban green space and pervious pavement. The objective of this research is to assess another approach for flood control measures, namely Sustainable Urban Drainage Systems (SUDS), with application to the Nhieu Loc - Thi Nghe Basin, located in the central part of Ho Chi Minh City. Conventional flood mitigation measures such as building flood gates and upgrading sewerage systems have been implemented but problems persist. Aims: In recent decades, Ho Chi Minh City, Vietnam, frequently has been affected by local floods and inundation from heavy rainfall.
