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, 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.
