Distributed Hydrologic Model:

tRIBS Hydrologic Modeling Platform.

TIN-based Real-time Integrated Basin Simulator (tRIBS)
tRIBS Google Group

The tRIBS model is a fully-distributed hydrologic model based on a triangulated irregular network (TIN). It has been developed for simulation and forecasting of watershed hydrology using rainfall estimates from gauges, weather radar or numerical weather models. The tRIBS model is capable of simulating basin hydrology continuously while preserving high-resolution data from remote sensing and field measurements.

Regional Land Surface Hydrology Model:

VIC Land Surface Model.

Variable Infiltration Capacity (VIC) model

The VIC model is a semi-distributed, macroscale land surface model that uses a grid-based simulation to solve full water and energy balances. It has been designed for application within coupled land-atmosphere-ocean general circulation models (GCMs). VIC is comprised of a simple three-layer characterization of the soil column and includes subgrid variability in land surface vegetation, soil moisture storage capacity as a spatial probability distribution, topography, precipitation, and base flow as a nonlinear recession. Streamflow outputs are routed separately from the land surface simulation, typically using the model of Lohmann et al., 1996 and 1998, implemented as RVIC.

GitHub Repository for VIC 5.1
This version of VIC has been modified and contains the following features: irrigation; urban impervious areas; and enhanced soil evaporation.



Datasets for Hydrologic Modeling of North America:

VIC Domain Files: This dataset contains the VIC-5 compatible domain files over the contiguous United States (CONUS) region with the precipitation disaggregation parameters described in Bohn et al. (2019).

INEGI Land Cover: The INEGI land cover dataset contains the land cover type over the Mexico that has been harmonized with the NLCD legend for years 1985, 1993, 2002, 2007, and 2011.

NLCD-INEGI Land Cover: The NLCD-INEGI is the harmonized US-Mexico land cover dataset merged from NLCD and INEGI dataset for years 1992, 2001, and 2011.

MOD-LSP: The MOD-LSP (MODIS-based land surface parameters) is a gridded land surface parameter set derived from 17 years of MODIS observations and NLCD-INGI land cover classifications that accounts for seasonal and interannual variability and long-term change over the CONUS region at 0.0625° spatial resolution and monthly temporal resolution (Bohn and Vivoni., 2019). MOD-LSP is formatted as inputs to the VIC model.

MIRCA-BC-USMX: The MIRCA-BC-USMX dataset contains a spatially explicit mean annual cycle of monthly planted and irrigated fractions at 0.0625 degree (6 km) spatial resolution over the continental United States and Mexico for years 1992, 2002, and 2012.

PITRI: The Precipitation Isosceles Triangle (PITRI) is the two-parameter deterministic approach that members of our team developed and utilize to more accurately estimate hourly diurnal cycles of precipitation from daily datasets.

GIS Algorithms:

TIN-Index Analysis Package (TIAP)

TIAP is a set of Arc/Info AML scripts that facilitate the creation of triangulated irregular network models utilizing concepts of hydrologic similarity and slope preserving criteria. The software package provides various options for the user to generate computationally efficient terrain representations from high resolution DEM products. A direct use of the program is for incorporation of TIN terrain into distributed hydrologic models.
