You can use a custom shape in SWMM 5 for a closed Link or if it is an open channel then you can use a Transect Section as in HEC-RAS

You use the custom shape,
Make a Table of Depth/Full Depth and Width/Full Depth

Two Methods to Calibrate RDII RTK parameters in H2OMAP SWMM and InfoSWMM

Two Methods to Calibrate RDII RTK parameters in H2OMAP SWMM and InfoSWMM

There are two methods to calibrate the RTK parameters for RDII Analysis in InfoSWMM and H2OMAP SWMM.  The two methods are similar but use a different approach to calibrate the data: 1.The RDII Hydrograph component of the Calibrator Add On also uses a Genetic Algorithm to calibrate the upstream RDII locations based on monitored flow but using the hydraulic network for the calibration.
2.The RDII Analyst uses a Genetic Algorithm to Calibrate the RTK parameters for one location using monitored rainfall and flow data.  This calibration does not take into account the hydraulic routing in the network.

Or how the invert, rim elevation, crown elevation of the highest connecting link, pressure depth and flooded depth interact during a simulation.
Level (invert of the Node) Elevation (crown – surcharged if the HGL is above the crown elevation) Ground (either a depth above invert or a Rim Elevation) Overflow is either lost, stored, increases the HGL, Inlet Controlled or flows to a 2D mesh depending on the values of Surcharge Depth, Ponded Area, Inlet Options or 2D Options, respectively

From 3QD - THE MATHEMATICS OF ROUGHNESS

Image
THE MATHEMATICS OF ROUGHNESSJim Holt reviews Benoit B. Mandelbrot's The Fractalist: Memoir of a Scientific Maverick, in the NYRB: Benoit Mandelbrot, the brilliant Polish-French-American mathematician who died in 2010, had a poet’s taste for complexity and strangeness. His genius for noticing deep links among far-flung phenomena led him to create a new branch of geometry, one that has deepened our understanding of both natural forms and patterns of human behavior. The key to it is a simple yet elusive idea, that of self-similarity.
To see what self-similarity means, consider a homely example: the cauliflower. Take a head of this vegetable and observe its form—the way it is composed of florets. Pull off one of those florets. What does it look like? It looks like a little head of cauliflower, with its own subflorets. Now pull off one of those subflorets. What does that look like? A still tinier cauliflower. If you continue this process—and you may soon need a magnifying glass—you’ll…
