The overall objective of this paper is to identify coastal zone management problems within Mombasa Diani area. Other objectives included evaluating the effectiveness of the existing control measures and identifying response strategies for the affected areas. The results showed that coastal dunes and beach ridges, cliffed coasts and backshore areas could be developed but with proper set back lin...

Based on a spatial model, the Martinique beaches and coastal wetlands are examined to identify the risks of coastal squeeze. In many cases coastal development prevents coasts from adapting by shifting landward. Also tourism infrastructure augments the vulnerability of beach reduction and mangrove squeeze. More than 70% of all Martinique beaches and 29% of mangrove forests are highly endangered ...

eighteen kilometers long coastal stretch from the new mangalore port in the north totalapadi in the south has been studied in order to understand shoreline changes and erosion/ accretion patterns that have taken place due to the natural processes and anthropogenic activities. shoreline changes and quantification of beach erosion/accretion were made using the survey of india topomap, multidated ...

This study challenges the paradigm that salt marsh plants prevent lateral wave-induced erosion along wetland edges by binding soil with live roots and clarifies the role of vegetation in protecting the coast. In both laboratory flume studies and controlled field experiments, we show that common salt marsh plants do not significantly mitigate the total amount of erosion along a wetland edge. We ...

Shoreline change was identified as a vital sign for the Southwest Alaska Monitoring Network because land loss or gain at the marine edge has important ecological and jurisdictional implications to resource managers of coastal National Parks. To evaluate the type of shoreline changes occurring along the 82 km coastline of Lake Clark National Park and Preserve, 7 of 10 cross-shore beach profiles ...

Erosion is a major threat for coasts worldwide, beaches in particular, which constitute one of the most valuable coastal landforms. Vulnerability assessments related to beach erosion may contribute to planning measures to counteract erosion by identifying, quantifying and ranking vulnerability. Herein, we present a new index, the Beach Vulnerability Index (BVI), which combines simplicity in cal...

In this study, we employ a choice-based conjoint survey design to elicit individual choices of beach erosion control programs that can potentially cause multiple effects on beach environment. Two empirical choice models which incorporate individual heterogeneity, are used to analyze and compare the elicited individual choices of erosion control programs. Our results show that to a typical indiv...

Global climate change and concomitant rising sea level will have a profound impact on Florida’s coastal and marine systems. Sea-level rise will increase erosion of beaches, cause saltwater intrusion into water supplies, inundate coastal marshes and other important habitats, and make coastal property more vulnerable to erosion and flooding. Yet most coastal areas are currently managed under the ...
