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.
Subject: What are the Equations for Weirs in SWMM 5, Part 2? There are four types of Weirs in SWMM 5: Transverse, Sideflow, V Notch and Trapezoidal. The trapezoidal weir is a combination of the Sideflow and V Notch Weir and the Sideflow acts like…
Read MoreSubject: SWMM 5 Leaping Weir Example The attached example shows one way how SWMM 5 RTC Rules can be used to have the low flow go down a leaping weir orifice and the high flow go over the weir to the downstream section of the…
Read MoreSubject: How to Approximate a Timer in the RTC Rules of SWMM 5 SWMM 5 does not have a explicit timer in its Real Time Control (RTC) rules but you can approximate it by using a Control Curve as in the attached example model. The…
Read MoreSubject: Sensitivity Analysis in InfoSWMM and H2OMAP SWMM It is easy to perform sensitivity analysis in InfoSWMM and H2oMAP SWMM using the Scenario Manager, Dataset manager, Block Edit in the Database Editor, Batch Simulation and theReport Manager. For example, we will do a … Read…
