Wave-current-seabed interactions in shallow water have both economic importance and relevance for researchers working on wave-tide-surge models. The turbulence resulting from such interactions induces sediment resuspension. Tidal-flow patterns and the behaviour of storm-surges are modified, leading to possible inaccuracies in tidal predictions and water-circulation models. In extreme cases under adverse meteorological conditions, accurate storm-surge warnings or the lack of them can have major economic and public safety implications. In deeper water, turbulent seabed interactions influence the movement of water masses, kinetic energy and sediment onto and off the continental shelf. Instruments which can measure comprehensively the phenomena leading to these interactions are still rare. However, modern electronics, improved energy sources and sensors, sophisticated software and greatly enlarged data-stores are encouraging engineers apparatus capable of monitoring the environment with adequate rigor. STABLE II is one of these new-generation instruments. Although a development of an earlier concept, it is actually a completely new apparatus. It has both improved endurance and capability, and represents an attempt to provide much of the information required by hydrodynamicists, modellers and sedimentologists.
