DeltaRCM
DeltaRCM is an organization of people who use, develop, and maintain the DeltaRCM ecosystem.
There are several versions of DeltaRCM floating around the web, and a central goal of this project is to reduce the number of different model branches, while maintaining flexibility for development by any users.
Overview of DeltaRCM models
pyDeltaRCM is the Python version of the Matlab deltaRCM model by Man Liang. This model was turned into a component for WMT, the Community Surface Dynamics Modeling System (CSDMS) Web Modeling Interface by Mariela Perignon and Mark Piper in ~2016.
Since then, the project has been organized here, and has continued to grow with new projects and contributors.
