Requirements

OS Dependency: Ripple requires Python version >=3.10 and a Windows environment with Desktop Experience (GUI, not a headless Windows server) and HEC-RAS installed (currently version 6.3.1 is supported).

Installing Ripple

NOTE: Using a python virtual environment is not required but is highly recommended.

Using pip

Activate virtual environment as shown below and install the ripple1d package using pip using PowerShell:

    pip install ripple1d

Verify the Installation

Verify the installation by importing ripple1d in a Python shell:

    python
    >>> import ripple1d
    >>> print(ripple1d.__version__)
