Sediment transport relates to suspended sediment and bedload. The suspended sedi‐ ment plays the most important role on the land-ocen sediment flux. On the other hand, the bedload should be considered in order to assess the impacts of dams on sediment transport and sediment yield. Recent effects of dam construction have been widely reported. The sediment load has been reduced by more than 75% f...
ROONEY, J.J.B., and FLETCHER, C.H. III, 2004. Shoreline change and Pacific climatic oscillations in Kihei, Maui, Hawaii. Journal of Coastal Research, 21(0), 000–000. West Palm Beach (Florida), ISSN 0749-0208. Increasing demands on coastal areas require enhanced understanding of coastal erosion hazards. Here we analyze a 5-km segment of the Kihei coastline (Maui, Hawaii) centered on an area of c...
Oyster reefs provide valuable ecosystem services that contribute to coastal resilience. Unfortunately, many reefs have been degraded or removed completely, and there are increased efforts to restore oysters in many coastal areas. In particular, much attention has recently been given to the restoration of shellfish reefs along eroding shorelines to reduce erosion. Such fringing reef approaches, ...
The process of erosion and desertification affects social communities, agricultural lands and natural resources in coastal areas. The rapid coastline changes would cause social and economic issues in the coastal areas. In this study, Miankaleh coasts and the eastern coastlines of Amirabad port have been surveyed due to existing benchmarks since June 2013 until December 2015 in order to analyze ...
The El Niño-Southern Oscillation is the dominant mode of interannual climate variability across the Pacific Ocean basin, with influence on the global climate. The two end members of the cycle, El Niño and La Niña, force anomalous oceanographic conditions and coastal response along the Pacific margin, exposing many heavily populated regions to increased coastal flooding and erosion hazards. Howe...
Depending on the amount of aeolian sediment input and dune erosion, dune size and morphology change over time. Since coastal foredunes play an important role in the Dutch coastal defence, it is important to have good insight in the main factors that control these changes. In this paper the temporal variations in foredune erosion and accretion were studied in relation to proxies for aeolian tran...
Marcel J.F. Stive The development of coastal erosion management addressing typical traditional erosion problems towards coastal zone management addressing the evaluation of alternative solutions to guarantee a variety of coastal zone functions on their economic time scale has necessitated the formulation of large-scale coastal evolution (LSCE) models. Using the coastal evolution of the Netherla...
This paper provides an overview of the coastline eroding occurrences in Ghana. Ghana is located in West Africa boarded at the south by the Gulf of Guinea and the Atlantic Ocean with four of its ten regions having its major cities lying along the coast. The coastline of Ghana has over the decades experience minor coastal erosion but the recent situation is becoming apocalyptic and needs further ...
