Tutorials

Teaching is the part of being a professor I missed most, so I kept doing it. This is the home for the free courses, video series, and walk-throughs I make for water resources engineers. Some have their own page; the rest live on GitHub or YouTube.

HydroMohsen on YouTube

The channel is where most of my short-form teaching lives. You will find recorded course lectures (water resources engineering and fluid mechanics), ArcGIS Pro walk-throughs, the Python for H&H videos that go with the course on this site, short demos of the open-source tools, and one-off explainers on whatever I am thinking about. New videos go up there.

Python Fundamentals for H&H Modeling and Analysis

A free, hands-on Python course for water resources engineers, built around real hydrologic and hydraulic workflows rather than abstract exercises. Six modules, all in Google Colab, with a getting-started video to walk you in. There is nothing to install.
