The CREST model is a distributed grid-based hybrid hydrologic model that simulates water and energy fluxes and storages in each grid cell. The core components of the model are rainfall-runoff generation, evapotranspiration estimation, sub-grid cell routing, downstream routing, and feedbacks between rainfall-runoff and routing mechanisms. The model conducts multi-scale hydrologic modeling through representing soil moisture storage capacity and runoff generation at sub-grid scale, and estimating intermediate hydrologic processes at different resolutions. The model is used for a wide variety of applications, including flood forecasting, water resources forecasting and climate change assessment studies. The model is appropriate for modeling small to regional basins.
The CREST model was developed in Fortran, and is capable of using different gridded input formats including DEMs, numerical model outputs, satellite derived products, radar rainfall data, and gridded in-situ measurements. The model can be run for different locations and is able to clip data for a specific region from the larger input region.
