ParFlow

ParFlow is a community developed, integrated hydrologic model that simultaneously solves overland flow and variably saturated groundwater flow. Traditional hydrologic models solve these systems separately whereas integrated models directly couple both domains. The development is a multi-institutional effort now hosted on GitHub: https://github.com/parflow

 

Example of an integrated hydrologic model simulated with ParFlow: Floods in North Cascade National Park

Complex Reactions & Particles

Lagrangian particle methods have advanced greatly in recent years and we are now able to realistically simulate the detailed processes of mixing that lead to chemical transformations in hydrologic systems.

The CRP code is hosted openly on GitHub and is free to use (https://github.com/nbengdahl/CRP). It is a prototype code and is best used as an example, but it is fully functional and will reproduce the examples from the associated publication.

We also have a recently developed parallelized version of the framework (without reactions) here: https://github.com/mschmidt271/reactivePT_accel_parallel
