Culvert Analysis Toolkit
This documentation is a work-in-progress
The Culvert Analysis Toolkit is a collection of GIS tools designed to support analysis of culvert performance within their watershed. It uses a lightweight version of a TR-55 Model that leverages inputs derived from geospatial data to calculate peak-flow and culvert capacity.
This software has been developed by CivicMapper in collaboration with GroundPoint Engineering, and encompasses work from a collaboration with the Cornell Soil & Water Lab (on GitHub @ github.com/SoilWaterLab) on their TR-55-based peak flow model. See Credits/Contributors for more information.
Getting Started
- Installation: get the Culvert Analysis Toolkit set up in ArcGIS Pro
- Data Guides: walk-throughs of the types inputs the tool requires and how to prepare them
- Analysis Guide: an overview of the tools and what they do. using the tool and working with the results
- Calculators: an explanation of the peak-flow and capacity calculators, with links to the underlying calculation code on GitHub
Who is this toolkit for?
The toolkit is designed to support understanding the efficacy of stormwater culvert infrastructure at a broad scale for planning purposes. To that end, the tool has two audiences:
- Planners, who can use the outputs to support decision-making
- Analysts, who are able to run the tool in GIS software and are comforttable wrangling the spatial datasets that are required inputs of the tools
What this toolkit is not
This toolkit is not:
- a replacement for engineering tools like HEC-RAS or SWMM
- appropriate for supporting the design and engineering of indivdual culverts

This repository represents an evolution of a previous effort, the Peak-Flow Calculator, which was a hard fork of the Water Lab's CulvertEvalution repository.
Made in collaboration with the Cornell S&W lab, this repository includes additional updates to the science of the from CulvertModel_2.1.
