The Hydrologic Simulation Program–Python (HSP2) watershed model is is a port of the well-established Hydrological Simulation Program - FORTRAN (HSPF), re-coded with modern scientific Python and data formats.
HSP2 (pronouced "HSP-squared") is being developed by an open source team launched and led by RESPEC with internal funding. Our list of collaborators is growing, now including LimnoTech and with additional support from the U.S. Army Corps of Engineers (Engineer Research and Development Center (ERDC), Environmental Laboratory), modelers at the Virginia Department of Environmental Quality, and others.
HSP2 currently supports all HSPF hydrology and detailed water quality modules.
Support for specialty modules is currently in progress. See our Release Notes_ for up-to-date details.
Read our wiki for more information on our motivation and goals for HSP2:

background on the initial release_.
HSPsquared is released under the GNU Affero General Public License (AGPL), copyrighted 2017 by RESPEC_.
HSP2 contains the hydrology and water quality code modules converted from HSPF, along with the main programs to run HSP2.
HSP2tools contains supporting software modules such as the code to convert legacy WDM and UCI files to HDF5 files for HSP2, and to provide additional new and legacy capabilities.
HSP2IO is new in v0.10 and contains an abstracted approach to getting data in and out of HSP2 for flexibility and performance and also to support future automation and model coupling. - NOTE: With v0.10 the I/O abstraction classes provide an alternate approach to running HSP2. Our plan is to migrate solely using the I/O abstracted methods, but we will maintain both approaches for for several more releases for backward compatibility.
docs contains relevant reference documentation.
examples contains examples of how to use HSP2, organized as interactive Jupyter Notebook tutorials.
tests contains HSPF use cases, their input files, code to compare HSP2 vs HSPF model outputs and code to test for performance.
We recommend getting started by:
Following our HSP2 Installation_ Instructions.
Opening our interactive JupyterLab_ HSP2 tutorials in the examples
sub-directory.
We recommend Python 3.10.
Python Package Index (PyPI) +++++++++++++++++++++++++++ Starting with version 0.11.0a1 we provide a PyPI wheel package for HSP2 which should work on any supported platform for Python 3.10, 3.11, and 3.12.
.. code-block:: console
python -m pip install hsp2Windows Executable ++++++++++++++++++ On the Releases_ page, we provide a Windows package in the zip file named HSP2_Driver_MonthYear.zip. HSP2_Driver_MonthYear.zip contains an .exe for running HSP2, enabling a user to run HSP2 without needing to do anything with Python code or Jupyter notebooks. The driver uses a file dialog to prompt for the name of the HDF5 file to run, or if that doesn't exist yet you can give it the name of a UCI or WDM file to import. It also runs with the H5 file name on the command line.
Clone or Download the HSPsquared Repository +++++++++++++++++++++++++++++++++++++++++++ From the HSP2squared Github page, download and extract the code using one of the options found by clicking on the green "Code" drop down button near the upper right of the page, or by downloading one of the compressed source files from the Releases page.
Place your copy of the HSPsquared folder in any convenient location on your computer.
For the rest of the installation steps, let's call this location
/path/to/module/hsp2.
Create a Python Environment +++++++++++++++++++++++++++ We provide two options to installing HSP2, yet recommend option 1.
Install using only one of these options.
Option 1: Install using "conda"
Follow these steps to install using the conda_ package manager.
1. Install the Anaconda Python Distribution
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Install the `latest release`_ of the Anaconda Distribution, which includes the
conda package manager, a complete Python (and R) data science stack, and the
Anaconda Navigator GUI. Follow `Anaconda Installation`_ documentation.
A lighter-weight alternative is to install Miniconda_.
2. Create a Conda Environment for HSP2 Modeling (optional)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Although HSP2 can be run from the default `base` environment created by
Anaconda, we recommend creating a custom environment that includes the exact
combination of software dependencies that we've in development and testing.
Use the following `conda create`_ command in your terminal or console:
.. code-block:: console
conda create -c conda-forge -n hsp2_310 python=3.10
Install the necessary and optional packages for HSP2 in the new environment:
.. code-block:: console
conda install -c conda-forge -n hsp2_310 cltoolbox numba pandas pytables
conda install -c conda-forge -n hsp2_310 h5py jupyterlab matplotlib notebook
.. code-block:: console
conda activate hsp2_310
cd /path/to/module/hsp2
pip install . # or "pip install -e ." to install in editable mode
You should now be able to run the Tutorials and create your own Jupyter
Notebooks!
Option 2: Install From Source Code Using `pip`Installing HSP2 using pip, the Package Installer for Python_
is an alternative method to installing with conda.
Install Python
^^^^^^^^^^^^^^^^^
Instructions for downloading Python to your computer based on your operating
system can be found in this helpful wiki_.
Create a Python Environment for HSP2 Modeling (optional)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Create a custom Python virtual environment for using HSP2, following the venv — Creation of virtual environments_ package documentation to create and
activate a new environment for running HSP2.
.. code-block:: console
python -m venv hsp2_env /path/to/python/virtual/environments/hsp2_envTo install using pip:
.. code-block:: console
source /path/to/python/virtual/environments/hsp2_env/bin/activate
cd /path/to/module/hsp2
pip install . # or "pip install -e ." to install in editable modeCommand Line Usage ++++++++++++++++++ Use the help to learn how to use the model and each sub-command:
.. code-block:: console
hsp2 --help
hsp2 import_uci --help
hsp2 run --helpIntended workflow from the command line:
.. code-block:: console
hsp2 import_uci import_test.uci new_model.h5
hsp2 run new_model.h5API Usage +++++++++ The HSP2 API is designed to be used in Python scripts and Jupyter notebooks.
