HEC-WAT

Current documentation for the HEC-WAT software is provided in an online, interactive format. User manuals, guides, example data, release notes and technical documentation are available at the HEC-WAT Documentation webpage.

User Manuals

HEC-WAT Users Manual contains an overview of the HEC-WAT software, core concepts, and user interface relevant to the HEC-WAT application itself.

Many pieces of HEC-WAT are implemented using a plugin architecture, with documentation for each plugin maintained and provided by the team responsible for those plugins. For plugins included with HEC-WAT, the following documentation is provided:

HEC-WAT Hydrologic Sampler Users Manual for the Hydrologic Sampler plugin.
HEC-WAT Plugins Documentation for other core HEC-WAT plugins.

Tutorials and Guides

For new users, we recommend reading the HEC-WAT Quick Start Guide which identifies key concepts and provides a step-by-step tutorial of setting up a HEC-WAT model. Additional HEC-WAT Tutorials and Guides are added and updated regularly by the HEC-WAT team.

Modeling Software

For modeling software used within a HEC-WAT study, please refer to the documentation for each for information about their specific features:

HEC-WAT Legacy Version 1.0. We strongly recommend users upgrade to the current release version of HEC-WAT 1.1 as we cannot provide any support for HEC-WAT 1.0. The user documentation for this legacy software version is archived below:
