Don’t Mesh This Up!

During the first week of October, I presented a webinar on the role of Terrain Surfaces and Surface Modifications.  The intent was to cover the role of the terrain surface in the calculation of flooding as well as to discuss … Continue reading

Need Speed? Get Model Simulation Results, When You Need Them

There’s no shortage of modeling packages available to calculate flooding depths. But what if you need to model 1D infrastructure and 2D surface flooding? Freely available 2D analysis tools can take hours, or days, to run complex rainfall scenarios and … Continue reading

Atlas 14 Temporals for XPSWMM

Back in January, we introduced the capabilities of XPSWMM that allows a modeler the ability to perform an ensemble-based critical duration analysis using the NOAA Atlas 14 Temporal Distributions. As the NRCS, formerly the Soil Conservation Service (SCS), retires the legacy … Continue reading

Continuous Simulation: Make Stormwater Assets Great Again

More than twenty years ago I wrote a Master’s Thesis about software tools that could be put together with EPA SWMM to create a toolbox for very long term continuous simulation for stormwater and watershed simulations.  I was inspired at … Continue reading

In Engineering, Change Is Good

by Matt Anderson, P.E., CFM Storm & Flood Products Manager Earlier this year, a small, simple internet meme on Linkedin caught my eye.  The meme contrasted the present state of “What is” and “What we need” against a future of … Continue reading
