I’m looking for short courses that move past software walkthroughs and dig into the fluid mechanics — numerical stability (CFL), turbulence closure choices, and validation workflows — for 2D flood routing. I routinely run HEC-RAS 2D and TELEMAC for urban drainage; if you’ve taken a 20–40 hour course that blends finite-volume theory with hands-on labs (OpenFOAM or similar) and includes a project using ADCP or high-water mark data, which providers delivered real depth?
Best 30–35 hours I’ve spent was the IHE Delft OpenFOAM for Environmental Flows short course, covering CFL limits, Godunov finite-volume details, and labs testing RANS vs k-omega closures. > TELEMAC for urban drainage; if you’ve taken a 20–40 hour course that blends finite-volume theory with hands-on labs That matched the brief, and I could carry the CFL and limiter choices back into HEC-RAS 2D/TELEMAC and tighten validation on two urban catchments. Small gotcha: it’s CFD-first (, turbulence tax), so you’ll need to translate a bit for flood routing, but it’s worth it.
I got a lot out of Deltares’ Advanced Hydrodynamics (D-Flow FM) short course; they derive stability limits, compare k–ε vs k–ω SST, and have you reproduce a dam-break and oblique bore for verification: https://learn.deltares.nl/courses/advanced-hydrodynamics-dflow-fm/. Practical tip: for wetting/drying in tight urban meshes, ramp dt for the first hour so early-step “CFL spikes” stay <0.7, and apply the limiter to momentum only — I’ve seen otherwise smooth stages develop phantom backwater near inlets when coupling to HEC-RAS.
