Summary Contact Technical specs In/Output Process Testing Other Component info Also known as tRIBS Model type Single Model part of larger framework Note on status model Date note status model 2025-09-08 Incorporated models or components: Spatial dimensions 2D Spatial extent Regional-Scale, Landscape-Scale, Watershed-Scale, Reach-Scale, Patch-Scale, Point-Based Model domain Terrestrial, Hydrology, Ecosystems One-line model description The TIN-based Real-Time Integrated Basin Simulator is a fully-distributed, continuous hydrologic model operating on a Triangulated Irregular Network (TIN). Extended model description The tRIBS model in this release (version 5.3.0 of September 8, 2025) under the MIT license includes: Hydrologic Processes: Soil moisture infiltration fronts and their vertical redistribution. Coupled dynamics of the vadose and saturated zones with a dynamic water table. Topography-driven lateral fluxes in the vadose and saturated zones. Radiation and energy balance components on complex terrain. Single layer snowpack accumulation, ablation and melt on complex terrain. Rainfall and snow interception on vegetation canopies. Evaporation of intercepted rainfall, soil evaporation and plant transpiration. Hydrologic hillslope routing, hydraulic routing in channels, level-pool reservoir routing. Computational Processes: Multi-resolution domain generated with channel network and watershed boundary. Computationally-efficient methods for infiltration, snow dynamics and flow routing. Serial operation for point-scale simulations and small watershed domains. Parallelized operation for large domains optimized through subbasin partitioning methods. Ingestion of time-varying meteorological forcing from stations or raster-based products. Ingestion of soil and vegetation parameters from tabular data or raster-based products. Pre- and post-processing workflows for time series and spatial analysis using Python.
