Autodesk Water Solutions Specialist | 50+ Years Shaping the Industry Master of the full hydraulic-hydrologic stack—from the pioneering days of SWMM3 to today’s cloud-powered InfoDrainage and ICM SWMM. My career spans every generation of SWMM, XP-SWMM, InfoSWMM, InfoSewer, Civil 3D Drainage Analysis, and InfraWorks, translating surface–subsurface interactions into future-ready infrastructure.
Control Rules Operational control rules determine how pumps and flow regulating structures (i.e., orifice and weir) in the conveyance system will be adjusted over the course of a simulation. InfoSWMM H2OMap SWMM InfoSWMM SA has the following three control classes. · Initial Status - The…
Read MoreRunoff Coefficients Runoff coefficient is loosely defined as the ratio of runoff to rainfall, and is a function of watershed characteristics including land use, soil type, and slope of the watershed. The value of runoff coefficient ranges between 0.0 and 1.0. A value of 0.0…
Read More2.5 Decomposing the Corrected Flow Data The corrected flow data can be decomposed into its DWF, GWI, and RDII flow components with the help of the rainfall data. The decomposition process is illustrated in this section. Determining the DWF Component The first step towards determining…
Read MoreSurface Runoff in InfoSWMM and InfoSWMM SA InfoSWMM and InfoSWMM SA offer 13 choices for modeling surface runoff (click on link to see more information on each method): Nonlinear Reservoir The Colorado Urban Hydrograph Procedure (CUHP) NRCS (SCS) Dimensionless Unit Hydrograph Method NRCS (SCS) Triangular…
Read MoreExample 5. Runoff Water Quality This example demonstrates how to simulate pollutant buildup and washoff in an urban catchment. The influence of different land uses on pollutant buildup is considered and both Event Mean Concentrations (EMCs) and exponential functions are used to represent the washoff…
