CREST-iMAP Model
Description
The CREST-iMAP model framework integrates hydrologic model (CREST) and hydrodynamic model (anuga) to target heavy rainfall-induced flash flood.
Taking advantage of two models, CREST-iMAP is capable of simulating hydrologic streamflows, flood extend, flood depth, pushing the territory of traditional 1D streamflow simulation to 2D (extent) and 3D (depth).
