Coastal zones constitute one of the most heavily populated and developed land in world. Despite utility economic benefits that coasts provide, there is no reliable global-scale assessment historical shoreline change trends. Here, via use freely available optical satellite images captured since 1984, conjunction with sophisticated image interrogation analysis methods, we present a occurrence sandy beaches rates therein. Applying pixel-based supervised classification, found 31% world's...

A new alternative to saving our beaches from local sea-level rise: the sand engine.A boldly innovative soft engineering intervention, comprising an unprecedented 21.5 Mm3 nourishment known as Sand Engine, has recently been implemented in Netherlands. The Engine is a pilot project test efficacy of mega-nourishments counter...
Muddy coasts provide ecological habitats, supply food and form a natural coastal defence. Relative sea level rise, changing wave energy human interventions will increase the pressure on muddy zones. For sustainable management it is key to obtain information geomorphology of historical changes along areas. So far, little known about distribution behaviour at global scale. In this study we present scale assessment occurrence rates coastline change therein. We combine publicly available...
Digital images of the intertidal region were used to map shorelines and bathymetry along four geo-morphically hydrodynamically distinct coastlines in United States, Kingdom, The Netherlands, Australia. Mapping methods, each which was originally designed perform well at only one sites, applied all results compared direct topographic surveys. It determined that rms errors image-derived versus directly surveyed elevations depended on prevailing hydrodynamic conditions as differences different...
Wave attenuation through mangrove forests has received more and attention, especially in the context of increasing coastal erosion sea-level-rise. Numerous studies have focused on studying reduction wave height a forest. However, understanding this process is still its infancy. In order to obtain insight, laboratory experiment, mimicking processes by mangroves Mekong Delta, Vietnam was conducted. The for different scenarios densities conditions investigated. A new method quantify vegetation...
Time‐averaged (over many wave periods) nearshore video observations show the process of breaking as one or more white alongshore bands high intensity. Across a known depth profile, similar dissipation can be predicted with model describing time‐averaged cross‐shore evolution organized and roller energy. This close correspondence between observed modeled proxies is used to develop new remote sensing technique, termed Subtidal Beach Mapper (SBM), estimate bathymetry. SBM operates on time...
Beach scarps are nearly vertical seaward facing sandy cliffs within the cross-shore beach profile. These features often associated with eroding (nourished) coastlines and can reach heights of O(2–3 m). An analysis a six-year dataset scarp presence at nourished Sand Engine shows that formation nourishment is linked to mildly erosive (summer storm) conditions, whereas destruction related extremely (winter conditions. Additional experiments were carried out showing formation, migration, from...
Recently, mega feeder nourishments have been proposed as a new strategy to nourish sediment-starving beaches. This involves the placement of large, concentrated sediment volume at single location along coast. Wind, waves and currents act natural agents spread alongshore over course years decades. article presents morphological development first full-scale implementation this strategy, examining 20 × 106 m3“Sand Engine” nourishment its impact on adjacent coastal sections. The analysis is...
Estuaries are among the most densely populated and heavily utilised regions in world, where crucial functions—e.g., freshwater availability water safety—strongly relate to natural dynamics of system. When developing nature-based solutions safeguard these essential functions, a thorough understanding estuarine is required. This study describes an elaborate sensitivity analysis on salt intrusion length using idealised estuary, which parametrically designed key estuary-scale parameters—e.g.,...
A video-based ARGUS coastal imaging system is being used at the northern Gold Coast, Australia to monitor and quantify regional-scale response sand nourishment construction of world-first Coast artificial (surfing) reef. This automated monitoring obtain hourly daylight images from four cameras that combined provide continuous coverage 4.5 km coast. Digital image processing techniques are then applied on a routine (weekly monthly) basis extract range CZM information growing database. Analyses...
Remote sensing methods are increasingly being deployed to measure and investigate morphology hydrodynamics in the littoral zone, across spatial scales ranging from centimetres kilometres, at time-scales seconds years. In past 5 years Australia, deployment of video-based coastal imaging systems has grown rapidly, by 2004, some 32 cameras were operating eight sites along coasts New South Wales Queensland. Coastal techniques applied a range coastline monitoring programs. Projects include large-...
