Coastal Engineering - Coastal Protection Structures
2016Η χώρα μας περιβάλλεται από ακτές μήκους 15000 km, μεγάλο μήκος από το οποία χρησιμοποιείται ως φυσικός πόρος με οικονομικο-κοινωνικά οφέλη: διακίνηση εμπορευμάτων/επιβατών μέσω των λιμένων, διάθεση λυμάτων, χρήση των αμμωδών παραλιών για αναψυχή κ.α. Ωστόσο τα τελευταία χρόνια η παράκτια ζώνη πιέζεται από περιβαλλοντικούς παράγοντες με σημαντικότερο ...

Innovations in Coastal Protection
2005Shore protection strategies include adjusting the activities of man (management) and adjustments to the physical system (engineering). Engineering activities fall into three classes: coastal hardening (armoring), reducing the transport and loss of littoral sediment, and adding sediment to the littoral system.

Economic and social demands for coastal protection
Coastal Engineering, 2005The purpose of this paper is to present methods and examples of economic valuation in the framework of cost–benefit analysis of coastal defense schemes. We summarize the concepts of value in economics and their application to coastal erosion defense. We describe the results of an original benefit transfer exercise on beach recreation, that is, whether ...

Coastal Protection for Ada, Ghana: a Case Study
Coastal Management, 2015Along the northwest African coast average rates of coastal retreat are between 1 and 2 m per year. In Ada, Ghana, the shoreline retreat rates have been in excess of 6 m per year at some specific locations. As a result of the ongoing erosion, various properties and existing infrastructure are being damaged and destroyed; also, due to the poor condition

Coastal protection in Singapore
Cahiers du Centre nantais de recherche pour l'aménagement régional, 1994Artificial changes to the coastline of Singapore dated from the 1820s. From 1960s large-scale reclamation was carried out to meet the demand for economic development. Two major methods were used to protect the newly reclaimed land : seawalls and revetments and breakwaters deployed in series. The use of the methods depends on a number of factors such as

Value of mangroves in coastal protection
Hydrobiologia, 1994Nearly 30% of the coastline of Malaysia is undergoing erosion. Many of these areas are coastal mudflats,fringed by mangroves. Behind the mangroves there are usually agricultural areas that are protected by bunds from tidal inundation. These bunds are constructed by the Department of Irrigation and Drainage and it is the policy of the department to ...
