It is envisaged that development authority and city planners would benefit from this coupled model. Thus, the validated model was used for flood hazard mapping. Comprehensive set of decision-support tools. PCSWMM includes: GIS for water management engineers.
Three major outlets were considered for model calibration for 2014, the model simulated runoff showed a reasonable match with field records – that is, R 2 = 0.782, R 2 = 0.719 and R 2 = 0.768 for the reaches Chaktai Khal, Rajakhali Khal and Mahesh Khal, respectively. PCSWMM is a professional tool providing stand-alone GIS and time series management for all aspects of water management. The use of HEC-HMS generated the runoff the PCSWMM model simulation was carried out for 760 conduits and 693 junctions in the city that was studied.
To feature flooding conditions, both hydrological and hydraulic model studies were carried out using the Hydrologic Engineering Center–hydrologic modelling system (HEC-HMS) developed by the US Army Corps of Engineers, and the personal computer storm water management model (PCSWMM). Incredibly easy to use and extremely comprehensive, PCSWMM is admired by over 5,000 clients in more than 85 countries. The field survey comprises cross-sectional data for tertiary drains these are then transferred for setting up the numerical model. PCSWMM, engineered by CHI in 1984, is the trusted, leading spatial decision support software for wastewater, watershed and stormwater management modeling. This aim of this study was to develop a flood hazard map through a field survey and numerical modelling. Inadequate drainage capacity often fails to offer the desired response in urban flooding.
