This paper presents algorithmic components and corresponding software routines for extracting shoreline features from remote sensing imagery and LiDAR data. Conceptually, shoreline features are treated as boundary lines between land objects and water objects. Numerical algorithms have been identified and devised to segment and classify remote sensing imagery and LiDAR data into land and water p...

BACKGROUND There are inconsistent reports about multiple sclerosis (MS) risk among migrants from low to high MS risk geographical regions. This study assessed the overall MS incidence and evaluated seasonality in birth and subsequent MS risk later in the life in second generation of migrants born and lived in Kuwait. METHODS We assessed the overall and gender-specific MS risk in second genera...

Changes in shoreline configurations accelerated due to global warming are world wide concern. Such changes not only affect the flora and fauna of those regions but also the livelihood of the coastal population. In the context, the 7517km long coastline of Indian coast behaves differently in different regions. Therefore, in order to assess the shoreline changes taking place in particular coastal...

This study focuses on the effects of changes in fluvial sediment supply on the plan-form shape of wave-dominated deltas. We apply a one-line numerical shoreline model to calculate shoreline evolution after (I) elimination and (II) time-periodic variation of fluvial input. Model results suggest four characteristic modes of wave-dominated delta development after abandonment. The abandonment mode ...

We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inte...

We welcome Sheppard's comments on our recent assessment of both ecological and geomorphic change at Diego Garcia Atoll in the central Indian Ocean [1]. Whilst our assessment incorporated numerous aspects of change, including movements of the lagoon rim shorelines, changes in the terrestrial vegetation on the lagoon rim and amendments to the bathymetry of the lagoon basin through dredging activi...

Development along marine and estuarine shorelines, coupled with the uncertain status of many species that use nearshore habitats, has generated a strong interest in both describing nearshore resources and understanding how to restore them. Advances in GIS technology and the wide availability of GIS software and inexpensive and powerful computers are improving our ability to manage complex natur...

We present a new empirical shoreline evolution model integrating longshore and cross-shore processes. It is designed for wave-dominated sandy coasts and includes feedback between shoreline and wave dynamics. It can also take into account non-erodible (e.g. rocks, artificial structures) contours and complex wave propagation patterns through the coupling with the spectral wave model SWAN. While t...

The mathematical model of the movement of the shoreline in a sedimentary ocean basin (A Shoreline Problem) is a Stefan problem with variable latent heat. Swenson et al. [1] utilized an analogy with one-phase melting problem and developed a mathematical model for movement of shoreline in a sedimentary basin in response to changes in sediment line flux, tectonic subsidence of Earth's crust and se...

Periodic seabed undulations, such as nearshore sandbars, are known to reflect incoming surface waves of twice the wavelength by the so-called Bragg resonance mechanism. In view of this property, longshore seabed-mounted bars were proposed long ago as a means of coastal protection against the high momentum of incident oceanic waves. Many theoretical, computational, experimental and field measure...
