Tools & Apps
Small, open-source tools I have built to take the tedium out of everyday water resources work: pulling climate, snow, and streamflow data; building unit hydrographs; processing precipitation grids; and post-processing HEC output. Most live on GitHub; a few are interactive apps you can run in the browser.
Apps and web tools
Point-and-click tools. The AORC Viewer runs entirely in the browser.
CN Generator
Gradio app that builds SCS Curve Number maps from land use and soil data, with the zonal summaries you need for hydrology.

There are other repos on GitHub too, including data subsets for published work and a couple of forks I have built on. The full list is one click away.
Running these here
A standalone HTML app, like the AORC Viewer, can live in this site's public/ folder and
be served straight from hydromohsen.com, framed by the site's header and footer. That was
one of the reasons for moving off Google Sites: it would not let me host my own pages. If you want one
of these embedded on the site rather than just linked, tell me which.
