ASBTRACT Some sectors of the west Portuguese coast are particularly endangered by erosion and flooding. Regional to local scale information, on coastline evolutionary trend, is valuable in that includes areas with relevant erosion. A continuous, high-resolution, dataset coastal evolution, from 1947 2015, between Figueira da Foz Nazaré, was achieved within Programme “Geological Coastal Hazard Ma...

In this paper, we extract the waterline from synthetic aperture radar (SAR) images to illustrate coastline change in Shanghai, China. Nine ERS-2 and ENVISAT SAR images acquired between 1998 and 2006 were selected and a new land-water classification scheme was implemented to obtain coastline. The results show that the seaward coastline change between 1998 and 2000 is faster in the eastern part a...

On wave-influenced river deltas, wave-driven sediment redistribution affects progradation, and therefore avulsions, while avulsions change where is delivered to the coastline, affecting coastline shape. Coastline shape, in turn, rates patterns. Here we use a numerical model investigate how asymmetry of wave climates delta avulsion behaviors, which are coupled with shape evolution. Increasing wa...

Airborne Doppler radar data, collected off the Pacific Northwest coast by a NOAA WP-3D Orion aircraft over an 8-h period on 8 December 1993 during the Coastal Observations and Simulations with Topography experiment, reveal the mesoscale structure of an intense frontal system while it was well offshore and as it approached within 20 km of the Oregon coastline. During the offshore stage, a portio...

In this article, we are dealing with the problem of coastline extraction in Very High Resolution (VHR) multispectral images (Quickbird) on the Normandy Coast (France). Locating precisely the coastline is a crucial task in the context of coastal resource management and planning. In VHR imagery, some details on coastal zone become visible and the coastline definition depends on the geomorphologic...

The coastal zone of Mekong delta is suffering under intense pressures from climate change as well as human intervention. Currently, the coastline evolution of Mekong delta is a complex combination of impacts due to (1) relative sea level rise i.e. the sum of eustatic sea level rise, natural and human induced subsidence (2) sediment transport rate changes at some sections due to change of wave c...
