Watershed Modeling — Python for Hydrology & Watershed Modeling Automation

Watershed Modeling

Python for Hydrology & Watershed Modeling Automation

Live siteBuilt with EleventyDeployed on Cloudflare Pages

A focused, production-grade reference for automating hydrologic workflows in Python — from raw elevation data all the way to simulated runoff hydrographs.

🌐 www.watershedmodeling.com

What this is

Watershed Modeling is a deep, code-first knowledge base for hydrologists, environmental engineers, and Python GIS teams who need to move hydrologic analysis out of desktop GIS and into reproducible, scalable pipelines. Every guide is built around concrete, runnable patterns: which library to reach for, why an algorithm behaves the way it does on a given terrain, and how to wrap it in a defensible pipeline with logging, idempotency, topology validation, and QA/QC against authoritative hydrography.

It is not a collection of surface-level tutorials. Each page pairs the underlying hydrology and algorithm mechanics with complete, copy-pasteable Python, validation protocols, and the failure modes that actually bite in operational work — memory exhaustion on 1 m LiDAR, projection artifacts, flat-area stagnation, equifinality in calibration, and more.

Who it's for

  • Hydrologists & environmental engineers automating delineation, routing, and rainfall-runoff modeling.
  • Python GIS developers building spatial pipelines with rasterio, richdem, pysheds, whitebox, geopandas, and shapely.
  • Research & agency technical teams who need auditable, reproducible workflows at regional-to-continental scale.

What's covered

The site is organized into four in-depth areas covering the full hydrologic pipeline:

Every guide is cross-linked so you can follow a technique from a broad overview down to a specific parameter, tool integration, or decision ("SRTM vs LiDAR", "10 m vs 1 m", "MFD vs D-Infinity").

How it's built

A static site generated with Eleventy from Markdown source, and deployed to Cloudflare Pages. Content lives in content/, templates and assets in src/, and the Eleventy configuration in .eleventy.js.

Watershed Modeling — Python for Hydrology & Watershed Modeling Automation
Watershed Modeling
Python for Hydrology & Watershed Modeling Automation
Live siteBuilt with EleventyDeployed on Cloudflare Pages
A focused, production-grade reference for automating hydrologic workflows in Python — from raw
elevation data all the way to simulated runoff hydrographs.
🌐 www.watershedmodeling.com
What this is
Watershed Modeling is a deep, code-first knowledge base for hydrologists, environmental engineers,
and Python GIS teams who need to move hydrologic analysis out of desktop GIS and into reproducible,
scalable pipelines. Every guide is built around concrete, runnable patterns: which library to reach
for, why an algorithm behaves the way it does on a given terrain, and how to wrap it in a defensible
pipeline with logging, idempotency, topology validation, and QA/QC against authoritative hydrography.
It is not a collection of surface-level tutorials. Each page pairs the underlying hydrology and
algorithm mechanics with complete, copy-pasteable Python, validation protocols, and the failure modes
that actually bite in operational work — memory exhaustion on 1 m LiDAR, projection artifacts,
flat-area stagnation, equifinality in calibration, and more.
Who it's for
  • Hydrologists & environmental engineers automating delineation, routing, and rainfall-runoff modeling.
  • Python GIS developers building spatial pipelines with rasterio, richdem, pysheds, whitebox, geopandas, and shapely.
  • Research & agency technical teams who need auditable, reproducible workflows at regional-to-continental scale.
What's covered
The site is organized into four in-depth areas covering the full hydrologic pipeline:
Every guide is cross-linked so you can follow a technique from a broad overview down to a specific
parameter, tool integration, or decision ("SRTM vs LiDAR", "10 m vs 1 m", "MFD vs D-Infinity").
How it's built
A static site generated with Eleventy from Markdown source, and deployed to
Cloudflare Pages. Content lives in content/, templates and assets in
src/, and the Eleventy configuration in .eleventy.js.
