Beyond sand and water: Opportunities for the continuous social, structural and morphological transformation of Puntarenas

The city of Puntarenas in Costa Rica is one of the many examples along the country’s pacific coast, where settlements have developed and survived by the extraction/exploitation of marine resources and the chain of industries that follow. Currently, these coastal communities are being affected by an amount of socio-economical issues, some...

Tasikoki Coastal Protection: A researched based advice into the mitigation of shoreline recession of the beach of the Tasikoki Wildlife Rescue and Education Centre

The beach adjacent to the Tasikoki Wildlife Rescue and Education Centre is one of the many beaches worldwide suffering from coastline recession. This loss of coast has a negative impact on the environment, local society and ecology. In general, shoreline retreat is caused by sea level rise (SLR) and erosion. The main objective of this research...

The effects of climate change on coastal management in the Hondsbossche Dunes: Analysis and modeling of aeolian sediment transport and dune growth

In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe.<br/>To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened.<br/>During the design process, the most favourable variant was to construct a dune and beach system in front of the...

Analysis of two coastal lagoons in Ghana

Two polluted Ghanaian lagoons are investigated and possible engineering solutions are suggested and researched.<br/>The first lagoon is the Sakumo lagoon, located between Accra and Tema. This lagoon is connected to the sea through a small culvert, which enables a limited amount of water exchange. Since a few years, fishermen have been unable to...

A hybrid solution for the Galveston Seawall: A study on the reduction of the hydraulic loads by a sand cover at the Galveston Seawall with the use of XBeach

The City of Galveston is protected from extreme storm impact by a 17-km concrete seawall facing the Gulf of Mexico. Recent investigations have shown that the seawall may not be sufficient any more to protect against a 1 in 100 year design storm. Since raising the seawall disconnects the city from the beach and may be very costly, a hybrid...

Coastal Conditions: Responding to the Partial Opening of the Haringvliet Sluice

How to, a landscape architect, design with coastal natural processes? Coastal areas have stronger and more fluctuating natural variables than many sites in more sheltered areas. Understanding the past, present, and future form of these processes will allow the designer to shape a form and program that works with the site-specific...

Impact Modelling of Hurricane Sandy on the Rockaways: Relating high-resolution storm characteristics to observed impact with use of Bayesian Belief Networks

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

Building with nature: Balancing the urban growth of Kochi’s coastal wetlands with their ecological structures

The project takes its roots in the annual floods that Kochi, a coastal city in South India, is faced with. Along with these floods, the city faces rampant destruction of mangroves and an urban development that follows no particular structure. Being a highly fragile economic and political setup, it is safe to say that urban development takes...

An intrinsic sediment tracing method using natural quartz- and feldspar luminescence

The goal of a sediment tracer is to give quantitative or relative feedback on (coastal) morphological changes or track either sediment or other particles (e.g. contaminations) in sediment dynamic environments. A sediment tracer is a visible or invisible marked (sediment) grain that is artificially injected or is present in-situ. This Master...

Morphological behavior of a non-equilibrium coastal profile: The response of the Maasvlakte-2 outer contour to a storm event

The objective of this study is to analyze and simulate the behavior of a non-equilibrium profile in a storm event, in particular, the Maasvlakte-2 (MV2). The MV2 is a large reclamation project at which both soft and hard sea-defenses are applied. Soft sea-defenses exhibit steep initial profiles during construction. Understanding how this sea...

Coastal Erosion Processes near sea dikes in Hai Hau district, Vietnam

The erosion problem in Hai Hau coastal district (Vietnam) is the subject of this thesis. The exact processes that drive this ongoing erosion however are not well defined yet, and therefore two main goals are defined. The first goal is to gain more insight into the processes that drive the ongoing erosion in Hai Hau. The second goal is to predict...

Study of the diffusion activity in case of non-breaking waves with a current

Sediment transport causes morphological changes of coastal areas, and it is one of the most important objects in coastal engineering study. Recently, various experiments have been performed to investigate the sediment transport mechanism under a combination of waves and currents and to find the underlying relationships among various parameters...
