Project Veracruz: An assessment for the eroding beach south of Veracruz

Due to frequently occurring storms, like hurricanes and cold fronts, the coasts around the Mexican port city Veracruz suffer from erosion. This is most severe at the beaches of Boca del Rio just south of the city of Veracruz. Here, small beaches can be found between large groynes. These groynes block the southward littoral drift significantly...

The state of the coast (Toestand van de kust). Case study: North Holland

Over more than a thousand years, the Dutch coast has been eroding for large stretches. Coastal retreat puts coastal functions (e.g. safety against flooding) under pressure. Since 1990, the Dutch policy aims at preventing further retreat of the coastline, but in the meantime taking the valuable dynamical behaviour of the coast into account....

Modelling nourishments through the Durban piers: Research of sediment transport and surf conditions

The Durban bight has a very dynamic and variable coastline which is constantly under attack by the Indian Ocean. To protect the Durban harbour from this energetic ocean, already in 1855 breakwaters have been constructed to protect the harbour and prevent sedimentation inside. The construction of these breakwaters and eventually extending these...

Case study Piçarras Beach: Erosion and nourishment of a headland bay beach

Master project report. Piçarras is one of the touristic beaches of Santa Catarina state in Brazil. Piçarras beach is a headland bay beach. In the bay irregular features like an island, rocky outcrops and shoals are present influencing wave propagation. In the south Piçarras is bounded by Piçarras river. The river mouth has been fixated in 1970,...

Erosion of the beach of Historic Varadero, Cuba

Master project report. This report handles the erosion problems on the main tourist resort of Cuba, Varadero, situated on the Peninsula de Hicacos. With a length of 22 km, a maximum width of 500 m, The Peninsula de Hicacos constitutes a natural barrier separating the shallow waters of Cardenas Bay from the Florida Strait (Figure 1-3)....

Erosion Negril Beach

The ongoing erosion of the Negril Beach has become worse the past decade. In most places along the coast line, the beach will be gone in approximately 10 years. This will result in a major decrease of incomes that are made by the local tourist sector. To prevent the erosion this study has been performed to find a feasible and affordable solution...

World-wide sand bypassing systems: Data report

This report was prepared in 1996/97 as background information for the assessment of bypassing systems for the Tweed River Entrance Sand Bypassing Project. The information contained within this report has been obtained from a number of sources. The authors wish to thank all those who have provided assistance. In particular, the advice and...

Nearshore sand extraction and coastal stability

During the second half of this century offshore sand extraction has become commonplace. There has been an important increase of sand demand to use on construction and coastal protection as well as for industrial purposes. On the other hand, the development in the dredging field has helped to the expansion of the process. Since nearshore dredging...

Zeespiegelstijging en de gevolgen voor de Nederlandse Kust

De temperatuur op aarde stijgt. Een gevolg van deze temperatuurstijging is zeespiegelstijging. Een ander gevolg zou kunnen zijn dat de weersomstandigheden kunnen veranderen. De gemiddelde windkracht zou kunnen toenemen waardoor de golfhoogtes kunnen toenemen. Ook de gemiddelde windrichting zou kunnen veranderen. Een en ander zal gevolgen hebben...

Gold coast nearshore nourishments

In 1988 a large nearshore nourishment at Gold Coast, Australia was carried out. InSeptember/October 1988 1.5 million m3 of sand was dumped nearshore between the -6m and -10m depth contour, in the most southern part of the Gold Coast beaches. Following these works, carried out by WestHam Dredging, further nourishment took place from November 1989...

Design of beach replenishment

In the Netherlands much land was captured from the sea. At the same time however along the coast severe losses of land occurred. The main reasons were sea level rise and effects of decreasing tidal volumes of estuaries. Besides there were the local effects of shifting tidal channels and periodical movements of the coastline. Building of groynes,...

A new coastal defence policy for the Netherlands

Translation of two Dutch governmental reports about the decision to maintain the Dutch coastline by means of artificial beach nourishment and to maintain the coastline of 1990 (so in fact compensate all erosion by artificial beach replenishment).

Coastal Protection and Dune Management in the Netherlands

Because dunes protect a large part of The Netherlands against coastal flooding and inundation, it is vital to guarantee the strength of these natural sea defenses. Besides sea defense, dunes have other functions. Sandy shorelines and dunes are frequently eroded. A legal framework has been developed that guarantees the required safety-level of...

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 11: Strand en duinsuppleties

In Technisch Rapport 11 (TR 11) wordt een overzicht gegeven van de strand- en duinsuppleties, welke ter compensatie van kusterosie zijn uitgevoerd. In 1988 is het "Handboek zandsuppleties" uitgegeven. Hierin is een schat van gegevens verzameld over het desbetreffende onderwerp. Dit rapport voorziet in een aanvulling op het handboek, met meer...

Trends in sand tranfer systems

The purpose of this paper is to discuss some of the factors that have been influential in the change of functional design of sand transfer systems . The more common man-made littoral barriers are presented with types of sand transfer systems employed at each type of barrier.

By-passing and backpassing with special reference to conditions in Florida

By-passing by natural action is mentioned with special reference to Florida Inlets and to some other inlets in the United States and abroad. Natural by-passing at harbors on open shores is dealt with briefly. Present status of by-passing plant operations in Florida is reviewed. Inasmuch as it is evident that by-passing plants - partly because of...
