Time-series remote sensing data, sediment cores, and water column profiles of fluid properties and suspended sediment concentration were utilized to examine the mechanisms and volumes of sediment exchange between the mangrove fringe and the coastal zone in French Guiana. Remote sensing estimates of sediment yield from mangrove shoreline erosion by wave attack during the f 30-year periods when o...

Shorelines at the interface of marine, estuarine and terrestrial biomes are among the most degraded and threatened habitats in the coastal zone because of their sensitivity to sea level rise, storms and increased human utilization. Previous efforts to protect shorelines have largely involved constructing bulkheads and seawalls which can detrimentally affect nearshore habitats. Recently, efforts...

Shorelines are desirable places to live, work, and play, but are also subject to flooding, erosion, and the movement of dynamic beaches. Such hazards can result in damage to property and the natural environment, social disruption, personal injuries, and loss of life. Increasing shoreline development has led to the need for public policies and regulations that effectively minimize the negative i...

The practically important problem of the wave run-up is studied in this article in the framework of Nonlinear Shallow Water Equations (NSWE). The main novelty consists in the usage of high order local asymptotic analytical solutions in the vicinity of the shoreline. Namely, we use the analytical techniques introduced by S. Kovalevskaya and the analogy with the compressible gas dynamics (i.e. ga...

Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelet...

This paper presents an analysis of present and future hydrological conditions at the Forsmark site in Sweden, which has been proposed as the site for a geological repository for spent nuclear fuel. Forsmark is a coastal site that changes in response to shoreline displacement. In the considered time frame (until year 10 000 AD), the hydrological system will be affected by landscape succession as...

Identification of reference conditions for ecological assessments of coastal ecosystems poses a challenging problem in highly modified landscapes. A method is described for characterizing disturbance in coastal ecosystems using remotely sensed land classification and other publicly available GIS data. Within ecoregions bordering the US Great Lakes coast, aquatic habitats bordering the shoreline...

Coastal mapping and shoreline change detection are critical to many applications, including navigation, coastal zone management, coastal environmental protection, and sustainable development. Field surveying and on-site investigation become inevitable to ensure the quality of coastal decision making. To provide innovative tools for governmental agencies to increase efficiency and reduce operati...

11 The growth of megacusps as shoreline instabilities is investigated by ex-12 amining the coupling between wave transformation in the shoaling zone, long-13 shore transport in the surf zone, cross-shore transport, and morphological 14 evolution. This coupling is known to drive a potential positive feedback in 15 case of very oblique wave incidence, leading to an unstable shoreline and the 16 c...
