Real-time wave height measurements using a cable type wave monitoring system in shallow waters

Abstract

We developed a cable type wave monitoring systemfor real-time observation of wave height in the coastal zone,comprising nine pressure sensors and a total cable length of 500m. The resulting wave height observations were discontinuous.Thus, we developed a new interpolation algorithm using shallowwaterwave speed. The resulting temporal and spatial variation inwave height was very realistic, but the algorithm is applicableonly between sensors spaced ≤ 100 m apart.Thus, we developed a new interpolation algorithm using shallowwaterwave speed. The resulting temporal and spatial variation inwave height was very realistic, but the algorithm is applicableonly between sensors spaced ≤ 100 m apart.
