Laboratory facility for conducting experiments to investigate the nature of tsunami inundation, tsunami-structure impact, and harbor resonance. Particularly suited for general testing of coastal infra
structures, nearshore processes research, wave hydrodynamics, floating structures, renewable energy devices, and numerical model validation. Consists of a large basin of water outfitted with a wave making machine that is designed to generate short- and long-period multidirectional waves.
The cosine of the angle between two vectorsusually between a vector and one of the basis axes defining a Cartesiancoordinate system. Three angles and thus three direction cosines arerequired to define
a vector direction in a three dimensional Euclideanspace.
