In the third chapter the beach...

Remote sensing of the river Rhine plume

The data content of remote sensing (RS) images of sea surface temperature (SST) and normalized water-leaving radiance (nLw), for the year 1998, with respect to the River Rhine plume, is investigated. Questions that this study tries to answer are: is it possible to identify the plume from the available RS images, and under which conditions is...

A study on the reconstruction of Los Acantilados Beach, Argentina

The city of Mar del Plata is situated some 400 km South of Buenos Aires, the capital of Argentina. The city has two main incomes, namely industry and tourism. In summer, beaches of this Atlantic Ocean faced destination are packed with typical Argentine beach tents, which can be rented, and people from all over Argentina come to Mar del Plata....

Verhoging waterkering Elahuizen

In het Integraal Waterbeheersplan Friese Waterschappen is aangegeven dat ongeveer 50% van de kaden in Friesland niet aan de gestelde veiligheidseisen voldoet. Naar aanleiding van dit plan is het Wetterskip Fryslan het projectbureau Oevers en Kaden opgericht dje het rapport Technische Normen Friese Kaden hebben uitgebracht. In dit rapport wordt...

Beach Nourishment and Artificial Surf Reef

Balneário Camboriú is a very touristy city in southern Brazil, situated in the five kilometer wide Camboriú Bay. Its main tourist attraction is the beach, which is 5800 m long and rather narrow with a dry width of 10 to 20 m. The city is facing several problems regarding the beach that have a negative impact on tourism. The main problems are:...

Een onderzoek naar nieuwe vormen van gemechaniseerde tunnelbouw

Voor het realiseren van een relatief korte oeververbinding gaat de voorkeur in Nederland uit naar het toepassen van een afgezonken tunnel. Dit heeft te maken met de enorme ervaring die er in Nederland is opgedaan met dit type tunnel en de functionele geschiktheid ervan. De methode kent echter ook een aantal nadelen, zoals het grote ruimtebeslag...

Integrated coastal development Angoche, Mozambique

The analysis of the Socio-Economic system sets the engineering problems in a broader perspective. It answers why a technical problem should be solved and in what kind of socio- economic environment. An insight in recent history shows that Angoche once was an important port and town for the Nampula province. Agro-Industry was the main economic...

Op dit moment spelen in Provincie Zuid-Holland twee belangrijke landuitbreidingsprojecten, te weten de Tweede Maasvlakte en Nieuw-Holland.Om tot een ontwerp van Nieuw-Holland te komen is er gekeken naar de functies en de interacties. In de functionele analyse is allereerst gekeken naar welke functies er behoefte bestaat. De belangrijkste...

Rehabilitation of the Mayabeque Beach: Determination of the main causes of erosion and proposal of several solutions

In this report the beach erosion problem at the Village of Mayabeque, located 60 km south of Havana at the South coast of Cuba will be investigated. Mayabeque is a small local holiday village. 20 houses are permanently inhabited and in the summer the population goes up to 3000, mostly Cuban people all spending there holidays here. Mayabeque...

Modelling the Rhine River Plume

When a river discharges into the sea it forms a river plume. The main property of these plumes is their buoyancy; fresh water discharged by rivers is less dense than the receiving, saline waters. Due to the rotation of the Earth, these plumes tend to turn to the right in the Northern Hemisphere after entering the sea. Previous studies...

Experimental research of wave overtopping on a breakwater with concrete armour units

Recent research has shown that also Tetrapods can be applied in single layer application under certain conditions (D'ANGREMOND, ET AL [1999], VANDENBOSCH, ET AL [2002]). However, the placing density of the Tetrapods has to be larger than in a normal single layer application. The recently developed Xbloc? is applied in a single layer. Both in...

De containerterminal van de toekomst: Literatuurstudie

Inventarisatie van ontwikkelingen van containerterminals. Gekeken is naar insteekhavens, kranen met verhoogde productiviteit, twin llifting en tandem lifting, toepassing van een bufferplatform, geautomatiseerde hijsvoertuigen en bovenloopkranen. Veschillende concepten zijn geanalyseerd en er is een weging uitgevoerd met verschillende criteria,...

Correlatie tussen schuifsterkte en indexparameters van slib

Koninklijke Boskalis Westminster nv heeft een model ontwikkeld waarmee de te behalen producties bij het baggeren van slib berekend worden. Belangrijke grondspecifieke invoerparameters voor dit model zijn de dichtheid en de ongeroerde schuifsterkte van de te baggeren grond. De informatie over de schuifsterkte van slib is soms niet of slechts zeer...

Overflow sampling of trailing suction hopper dredgers

Turbidity is recognised as one of the major environmental problems of dredging. To get a handle on this problem the Dutch dredging industry (VBKO) commissioned a research project to develop software capable of predicting how much sediment is released into suspension during dredging operations. Major field measurement exercises are carried out in...

Foreign Financing for Coastal Infrastructure in Developing Countries

While foreign investments in developing countries are declining each year, the need for help and funding grows steadily. In the coastal zone the effects of over-population, pollution and changes in climate are becoming ever clearer. This requires a suitable policy to tackle the increasing number of problems and provide the coast with the...
