Public Library of HYDRUS projects
Below, you can find a large number of HYDRUS projects that have been developed over the entire history of HYDRUS. Thus some examples, were developed for Version 1, others for Version 2, and still others for Version 3. In general, it should be possible to convert all these examples (developed with earlier version of HYDRUS) into the latest format and rerun them using the latest version of HYDRUS.

Projects for Non-Standard External HYDRUS Modules (formally not part of the standard HYDRUS software)
We will be expanding the public library of HYDRUS projects in the near future. We welcome suggestions regarding the types of projects you would like to download here.
Instructions to install additional projects after downloading:
You can either unzip downloaded HYDRUS projects directly into any existing HYDRUS Project Group (e.g., Direct or Inverse) or create a new Project Group. If you unzip downloaded HYDRUS projects into any existing Project Group, then the downloaded projects will be immediately visible using the Project Manager. If you want to create a new Project Group for downloaded projects, follow the instructions below to make them visible in the Project Manager:
- Unzip downloaded HYDRUS projects into a single folder.
- Start HYDRUS and open the Project Manager.
- From the Project Groups Tab click New.
- Define the Name (e.g., Meteo, VZJ, Fracture) and Description (e.g., Drip irrigation into a loamy soil), and browse to the folder with downloaded HYDRUS projects.
- After clicking OK, the new Project Group should be fully defined and accessible using the Project Manager.
