PCSWMM Real-Time provides flood forecasting for watershed, storm sewer and/or sanitary sewer networks. The system provides accurate near-term (2-3 h) and generalized long-term (24 h +) forecasting of rainfall, runoff, flows, and water levels throughout the system, whether it is river-based, sewer-based, or both.
With support for raingage calibrated radar rainfall, integrated 1D-2D surface modeling, distributed or lumped hydrology, groundwater, snowmelt, and highly detailed hydraulic modeling of river systems and/or urban drainage systems, PCSWMM Real-Time's real-time hydrologic/hydraulic models can be leveraged for multiple purposes beyond flood forecasting, including floodplain delineations, remediation studies and masterplanning.
Input function support includes real-time radar and raingage data, as well as real-time flow gages and climatology inputs (temperature, windspeed). Real-time control of gates, pumps, etc. is provided through control rules, or real-time operator inputs. Groundwater can be modeled, as well as snowmelt. Based on a real-time continuous modeling approach, antecedent conditions are preserved, and computed forecasts are updated every 5 minutes during wet weather.
PCSWMM Real-Time's GIS engine provides instantaneous animations of forecasted flood inundation extents, as well as flood vulnerable asset analysis. The decision support environment is web based with anywhere access through excellent mobile device support and automated communications.
PCSWMM's Real-Time approach can be divided into 4 components, all of which are included in a PCSWMM Real-Time server license (contact CHI for more information and pricing):
