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

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