Dune foot behaviour and erosion of sandy coastal defences in annual storm conditions

Storm surges cause elevated water levels, potentially leading to dune erosion, which is crucial to understand due to the protective function of dunes and sandy coastal defences against flooding. Dunes are dynamic systems, extensively studied through flumes and field observations. Collecting hydrodynamic and morphological data from erosion-prone...

Land of sand: reclaiming the sea, landscapes and lives in Malacca, Malaysia

Today, the landscapes of Asia—and Southeast Asia in particular—are undergoing major transformations, many of which are due to urbanisation processes that impact coastal areas. These are often controversial reclamation projects, generically referred to as the ‘war of sand’—an (in)visible conflict named for the raw material used to develop...

Engineering an Ecological Civilization Along Shanghai’s Main Waterfront and Coastline: Evaluating Ongoing Efforts to Construct an Urban Eco-Network

Recent ecological civilization policies make clear that China is willing to play a leading role in a sustainable green transition. But there are still discrepancies in definitions, appreciation and evaluation of ecological assets. This paper examines how Shanghai works on a sustainability transition, with a focus on its main urban waterfronts...

Puerto San Vicente, Chile: Evaluation of a Port Expansion

This report is written with the aim to evaluate a possible port expansion in the port of San Vicente, Chile. In order to achieve this a thorough analysis on the port operations, hydrodynamical analysis using Delft3D and a bottleneck analysis on the infrastructure have been executed. A preliminary design for the port expansion is created. This...

The effect of initial concentration on the consolidation behaviour of mud: A study on lake Markermeer sediment

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

The Impact of Historical Geography and Agricultural Land Development Processes on Wetland Restoration Methods Used to Create Ecological Networks: A Comparison of Japan and the Netherlands

In the Osaka area in the 1880s, rice was grown mostly in dry fields in upland areas, and a few paddy fields were situated on the natural wet landforms along the major rivers and streams on the Osaka Plain. As the area developed, dry fields became irrigated, and the lowland fields were filled and converted to urban land uses. For the Osaka city...

Manado: A Developing Coast

Manado, the capital city of North Sulawesi in Indonesia, is rapidly developing. The last years Manado has been extending into the sea, which changed the hydraulics and morphology of Manado Bay. This had negative effects on the currents, inducing erosion along the coast. Also Manado has problems with the presence of garbage in the rivers and...

Integral Design of Work Channels and Basins for the Execution of Dredging Projects

During the execution of reclamation projects by Boskalis, often a temporary work channel and basin are required. This work channel is used by the dredging equipment to reach the project site as close as possible. The project site is often located in very shallow water which makes a channel necessary. The basin is used to transport the dredged...

Polder Container Terminal

New ports are mostly constructed on low lying coastal land or in shallow coastal waters. The surface level of the land for port facilities is then raised to a level well above the highest water mark. This requires vast volumes of good quality fill material often dredged from the sea. Besides the cost of dredging, there is the environmental...

Cross-shore sediment transports on a cut profile

People always want to live near water and all over the world the areas near the sea get more and more built with houses, hotels and infrastructure. For this reason there is a trend to reclaim land by making an artificial island near or against the existing coast. Examples are the airport 'Chek Lap Kok' in Hong Kong and the 'Plan Waterman', a...

Closure of the Shiwa Tidal Basin

South Korea suffers from a high population density and stands therefore in need of agricultural and industrial land. The Koreans are seeking for solutions to solve this problem. One of the possibilities is to reclaim land from the sea. Several land-reclamation projects have already been carried out and one of the projects that is at the moment...

Saemankeum Comprehensive Tideland Reclamation Project: Feasibility Study on Hydraulic Filling of Seadikes

The Saemankeum Comprehensive Tideland Reclamation Project has as objective the reclamation of the extensive tidal flats in the estuaries of Dongjin river and Mankyung river for, among others, agricultural, urban and industrial use. The project includes the construction of a number of closure dams with a total length of some 34 km. Due to the...
