Abstract
This article presents an introduction and overview of a modelling project "TeraWatt: Large scale interactive coupled 3D modelling for wave and tidal energy resource and environmental impact".
The project was funded by the SUstainable PowER GENeration (SUPERGEN) "Marine Hub". SUPERGEN is an initiative of the Research Councils UK (RCUK) Energy Programme, led by the Engineering and Physical Sciences Research Council (EPSRC). It is focused on supporting resilient and sustainable generation, supply, transmission and storage of the UK's energy. The Marine Challenge addresses the UK Centre for Marine Energy Research's (UKCMER) mission to support the wave and tidal energy sector beyond their current state of development.
