Wave overtopping of sea defences poses a hazard to people and infrastructure. Rising sea levels and limited resources mean accurate prediction tools are needed to deliver cost-effective shoreline management plans. A dearth of in-situ data means that the numerical tools used for flood forecasting and coastal scheme design are based largely on data from idealised flume studies, and the resulting overtopping predictions may have orders of magnitude uncertainty for complicated structures and some environmental conditions. Furthermore, such studies usually only provide data on the total volume of overtopping water, and no data on the speed of the water. Here we present WireWall, an array of capacitance-based sensors which measure the speed and volume of overtopping water on a wave-by-wave basis. We describe the successful validation of WireWall against traditional flume methods and present results from the first trial deployments at a sea wall in the UK. WireWall results are also compared with numerical predictions based on EurOtop guidance. WireWall technology offers an approach for reliable acquisition of the data needed to develop resilient coastal protections schemes.

“…The wave detection parameters include the height, direction and waveform. Based on differences among the measurement methods, wave detection techniques can be classified into various types, such as aerometry, photogrammetric techniques [4], radar measurements [5], electronic measurements [6], optical measurements [7], and acoustic measurements [8]. The photogrammetric method is a non-contact measurement technique; this means that no sensors are launched onto the water surface, and the propagation of waves is not impacted.…”

The wave is an important hydrological element in marine research. Accurately describing the characteristics of waves is therefore significant to the study of marine power. The contents of this article are as follows: (1) a wave height measurement system using binocular cameras is proposed, and the small tank experiments are conducted to prove the efficacy of the proposed system; (2) based on the scale invariant feature transition (SIFT) algorithm, sub-pixel Harris corners are calculated in the difference-of-Gaussian (DOG) space to locate key points more accurately; and (3) a bi-directional epipolar constraint is employed to decrease the mismatch rate and computation time.

“…Ripples on water, sound and light are all waves incorporated with transverse waves [2], [3]. With existing technologies, harvesting energies accumulated with these waves are attainable [4], [5]. However, harnessing wave energy is not a simple process due to the unpredictable waves.…”

This study focused on the design and construction of a Low-Cost Device with Data Logger using Arduino Microcontroller capable of profiling the transverse wave. Series of low-cost potentiometers were used as sensor in profiling the transverse wave. The device resembled a long boat with two floaters on each segment that is deployed on the pool and sea. Results showed that the integrated measurement system was able to give statistically accurate data. Furthermore, the final prototype was able to profile a wave in terms of its sinusoidal attributes, i.e. amplitude (height), frequency and period.
