Environmental Modeling and Software Publication

A new publication in Environmental Modelling and Software (Raming et al., 2025) describes an open-source Python package to initialize, execute, and analyze tRIBS simulations. Congratulations to the authors associated with the Center for Hydrologic Innovations!

• Abstract: Distributed hydrologic models (DHM) are essential tools for understanding how and where water moves through a landscape. However, DHMs can be time-consuming and challenging to setup, limiting their application. Here, we present pytRIBS, a tool that addresses these challenges for the TIN-based Real-time Integrated Basin Simulator (tRIBS). pytRIBS is an open-source Python package with an object-oriented design to initialize, execute, and analyze tRIBS simulations. This package mirrors a tRIBS workflow with five preprocessing classes (Project, Mesh, Soil, Land, and Met) that can be used together or separately to obtain and convert data into a tRIBS format. Finally, the Results class manages outputs, provides analytical tools, and visualizes results. We illustrate the capabilities pytRIBS with an example case study of the Newman Canyon watershed, AZ, USA.
