Advanced stormwater modeling has had a huge impact on our industry over the last decade. Modeling has allowed us to analyze complex systems at a city-wide scale that was previously unthinkable. These models allow us to quickly identify the problem and facilitate the implementation of potential solutions. But are these solutions practical or even constructible in the “real world”? Have these solutions been evaluated outside of the “model world”? This presentation will dive into what is recommended when evaluating proposed solutions and discuss lessons learned when comparing the constraints of the real world with the model world.
