Abstract This paper studies the problem of unsupervised detection geometrically similar fragments (segments) in curves, context boundary matching. The goal is to determine all pairs sub-curves that are similar, under local scale invariance. In particular, we aim locate existence a section (independent length and/or orientation) second curve, first as indicated by user. proposed approach based o...

The Dutch coast is one of the most heavily nourished coasts globally. An average 12 mln. m 3 annually added to coastline only 432 km for dynamic conservation. This study provides an overview operational aspects more than 300 nourishments maintenance that have been performed since 1990s and discusses evolution nourishment approach lessons learned with regard design. first were beach dune repair ...

Landscape evolution over the last 8000 years in three areas located along Tuscany, Latium, and Campania coasts (central Tyrrhenian) has been deduced through a morphological, stratigraphical, historical approach considering physical human activity. Between 6000 yr BP, Sea Level Rise (SLR) dominated and, near river mouths, inlets occurred. In Tuscany area, Mt. Argentario was an island to SE of An...

Galician Rias are fluvial valleys that were flooded during the last marine transgression in Atlantic margin. The study of fossil dunes Cies Islands, a small archipelago mouth one rias (Ria de Vigo), allowed us to reconstruct coastal evolution from end Late Pleistocene present day. During this period, sea-level was 100 metres below and shoreline located about 5–10 kilometres away. About 15,000 y...

As coastal species experience increasing anthropogenic pressures there is a growing need to characterise the ecological drivers of their abundance and habitat use, and understand how they may respond to changes in their environment. Accordingly, fishery-independent surveys were undertaken to investigate shark abundance along approximately 400 km of the tropical east coast of Australia. Generali...

A USGS scientist collects data from an automated sampling system moored in Malibu Lagoon (July 2009). Photograph by John Izbicki, USGS. Each year, over 550 million people visit California’s public beaches. To protect beach-goers from exposure to waterborne disease, California state law requires water-quality monitoring for fecal indicator bacteria (FIB), such as enterococci and Escherichia coli...

Hurricane risk characteristics are examined across the U. S. Gulf of Mexico coastline using a hexagonal tessellation. Using an extreme value model, parameters are collected representing the rate or λ (frequency), the scale or σ (range), and the shape or ξ (intensity) of the extreme wind distribution. These latent parameters and the 30-year return level are visualized across the grid. The greate...

Knowledge of horizontal relative dispersion in nearshore oceans is important for many applications including the transport and fate of pollutants and the dynamics of nearshore ecosystems. Two-particle dispersion statistics are calculated frommillions of synthetic particle trajectories from high-resolution numerical simulations of the Southern California Bight. The model horizontal resolution of...

Upwelling jets flow alongshore in approximate geostrophic balance with the onshore pressure gradient induced by coastal upwelling. Observations of such jets have shown that they often move offshore downstream of capes, leaving a pool of upwelled water inshore. Comparisons are made between this behavior and the hydraulic transition of a potential-vorticity-conserving coastal current as it passes...

This article presents the geomorphological mapping of Kalamas river delta in Thesprotia (Epirus, north-western Greece). The (also known as Thyamis) is one three main deltas this region. Detailed was performed through analysis field surveys and interpretation old maps, satellite images, aerial photos, DEM. evolution well its current morphology derives from complex interactions between alluvial, ...
