“…The US Army Corps of Engineers Field Research Facility, located in Duck, North Carolina, is one of these sites with a continuous detailed monitoring of offshore and nearshore directional wave spectra, beach profiles and daytime video monitoring of the nearshore, and intensive process studies (Birkemeier et al 1996;Holman and Stanley, 2007). The Petten dike in the Netherlands (Wenneker et al 2016), Narrabeen beach in Australia (Turner et al 2016) or Truc Vert beach in France (Castelle et al 2014) are other examples of coastal locations dedicated to long-term monitoring survey. At these sites, observations of sea level right at the shoreline have been combined with measurements of waves and nearshore topography to produce empirical parameterizations (see Section 4.1.3), suggesting that observing surf zone topography and waves outside of the surf zone could be a first step to extrapolate regional scale storm surge levels all the way to sea levels right at the coast.…”

“…Thornton and Guza 1986). Other instruments used routinely from structures include run-up gauges (Wenneker et al 2016) and shore-based video systems (Holman and Haller, 2013). With the progress made on estimating variables from video imagery, such as wave height, sea level and runup, and morphology, this technique offers now access to an unequalled high frequency (hourly) and long-term description of the nearshore dynamics (Pianca et al 2015;Almar et al 2017;Brodie et al 2018) Holthuijsen et al 2003), which are typically negligible on natural topographies (e.g.…”

The Contribution of Wind-Generated Waves to Coastal Sea-Level Changes

et al. 2019

Surface gravity waves generated by winds are ubiquitous on our oceans and play a primordial role in the dynamics of the ocean-land-atmosphere interfaces. In particular, wind-generated waves cause fluctuations of the sea level at the coast over timescales from a few seconds (individual wave runup) to a few hours (wave-induced setup). These wave-induced processes are of major importance for coastal management as they add up to tides and atmospheric surges during storm events and enhance coastal flooding and erosion. Changes in the atmospheric circulation associated with natural climate cycles or caused by increasing greenhouse gas emissions affect the wave conditions worldwide, which may drive significant changes in the wave-induced coastal hydrodynamics. Since sea-level rise represents a major challenge for sustainable coastal management, particularly in low-lying coastal areas and/or along densely urbanized coastlines, understanding the contribution of wind-generated waves to the long-term budget of coastal sea-level changes is therefore of major importance. In this review, we describe the physical processes by which sea states may affect coastal sea level at several timescales, we present the methods currently used to estimate the wave contribution to coastal sea-level changes, we describe past and future wave climate variability, we discuss the contribution of wave to coastal sea-level changes, and we discuss the limitations and perspectives of this research field.

“…Changes in the environment are also taking place in our system. Due to coastal protection activities, the creation of new dunes and sand supplementation has already covered important foraging patches (breakwaters) (van Koningsveld & Mulder 2004, Freriks 2015, Wenneker et al 2016. These changes create a natural experiment in which we can test whether individuals with high site fidelity can adapt less well when their foraging habitat is disappearing.…”

Many populations consist of individuals that differ consistently in their foraging behaviour through resource or foraging site selection. Foraging site fidelity has been reported in several seabird species as a common phenomenon. It is considered especially beneficial in spatially and/or temporally predictable environments in which fidelity is thought to increase energy intake, thereby affecting time‐energy budgets. However, the consequences for activity and energy budget have not been adequately tested. In this paper, we studied the consequences of fine‐scale foraging site fidelity in adult Herring Gulls Larus argentatus in a highly predictable foraging environment with distinct foraging patches. We measured their time‐activity budgets using GPS tracking and tri‐axial acceleration measurements, which also made it possible to estimate energy expenditure. Individual variation in foraging site fidelity was high, some individuals spending most of their time on a single foraging patch and others spending the same amount of time in up to 21 patches. While time and activity budgets differed between individuals, we found no clear relationship with foraging site fidelity. We did find a relationship between the size of the birds and the level of site fidelity; faithful birds tend to have a larger body size. Although differences in foraging time and habitat use between individuals could play a role in the results of the current study, short‐term consequences of variation in foraging site fidelity within a population remain elusive, even when focusing on individuals with a similar foraging specialization (Blue Mussels Mytilus edulis). Studying individuals over multiple years and under varying environmental conditions may provide better insight into the consequences and plasticity of foraging site fidelity.

“…Major modes of signal measurement in data acquisition include the serial ( [17], [18]), parallel ( [19], [20]) and distributed ( [21], [22]), etc. The serial mode has found more applications such as in river dikes ( [23], [24]), sea dikes ( [25], [26]) and road dikes ( [27], [28]). The distributed mode has found certain applications ( [14], [15]).…”

“…The land-based instruments, in addition to the sea-based instruments located at MP6, MP67, MP7, and MP8, were connected to a computer through a cable based on the coaxial protocol and RS485. Furthermore, the Qinsy online system was in place to ensure synchronic, real-time, and remote data transmission [25]. In the dike monitoring system, the serial mode is adopted for data acquisition, but the coaxial protocol and RS485 are used for data transmission, which is categorized as the quasi-distributed mode.…”

In the traditional system of dike monitoring, the acquisition apparatus is usually adopted with lots of built-in multiple data acquisition units. Each sensor is connected to the acquisition unit by wire, leading to the intensive use of wires. As a result, it is easy to cause inter-wire interference and signal distortion, compromising the accuracy and efficiency of dike monitoring. We have described and demonstrated a novel mode of signal acquisition that involved the integrated use of digital communication and human-computer interaction, and developed a separable online system of dike monitoring. Specifically, a parallel mode was adopted between the acquisition apparatus and the acquisition units; a serial mode was adopted between the acquisition unit and sensors; and a human-computer interface was used to control the monitoring process. Our research findings have shown that the parallel-serial mode not only proves to have a higher level of precision and efficiency than the serial mode, but also a simpler structure than the parallel mode alone under the same conditions. The acquisition unit adopting the parallel-serial mode could be separated from the acquisition apparatus and set up at nearby monitoring sites. This mode helps avoid such problems as massive amount of wiring as well as severe attenuation and interference of sensor signals in the serial mode, and is thus suitable for the linear dike monitoring. The parallel-serial mode has been successfully applied to the dike monitoring of the Yangtze River, and can also be used for scattered, linear, regional, and wide-range monitoring of engineering projects.
