GEB (Geographical Environmental and Behavioural model) simulates the environment (e.g., hydrology, floods), the individual people, households and organizations as well as their interactions at both small and large scale. The model does so through a "deep" coupling of an agent-based model a hydrological model, a vegetation model and a hydrodynamic model. You can find full documentation here.
The figure below shows a schematic overview of GEB.

FAQ
How is GEB pronounced?
It’s pronounced as "geb" (/ɡɛb/), with the "g" as in "get" or "gate", aligning with how ancient Egyptians would have likely pronounced the name of their god of the Earth: Geb.
