Measuring oblique wave run-up and overtopping with laser scanners

Classification of bore patterns induced by storm waves overtopping a dike crest and their impact types on dike mounted vertical walls – A large-scale model study

Short duration bores in the coastal zone are generated by wave breaking in shallow water and mild foreshore conditions. In storm weather situations and for sea level rise scenarios, these bores approach the dike and interact with previously overtopped or reflected bores. Combined laser scanner and video measurements were used to study the...

Numerical simulation of wave attack on sea dike with asphalt concrete revetment

The numerical simulation of wave attack on a sea dike with an asphalt concrete revetment during a severe storm is carried out using the dynamic Finite Element Method. When wave loads attack the revetment during such a storm, both the revetment and the underlying soil may be damaged. The two-phase flow equations are considered, to study the...

The application of a tandem dike system in Vietnam

In the low-lying coastal regions coastal defense structures are usually designed with a main function to protect the hinterland from highly vulnerable of sea flooding. Sea dikes are usually the most common and important elements which form the coastal flood defense system. Sea dikes are designed at a pre-defined circumstance and requirement. For...

Strength of the landward slopes of sea dikes in Vietnam

The landware slopes of sea dikes in the north of Vietnam are steep and solely constructed by soil covered with grass due to the budget constraints and also the out-of-date design guidelines.The resistance against erosion due to wave overtopping of several grass covered slopes were tested with the Wave Overtopping Simulator to show if a slope...

EAK2002 - Empfehlungen für die Ausführung fon Küstenschutzwerken

The ‚Guidelines and Recommendations for the Design of Coastal Structures (EAK)‘ published in 1993 (Die Küste, H. 55) have been revised based on today’s scientific knowledge, technical development and practical experience of the past years. Major parts of the recommendations have been re-written. Together with the unmodified recommendations, D, E...

Van dijkversterking naar dijkvervaging: Onderzoek naar de mogelijkheden van brede waterkeringen in Groningen.

Climate change will cause increasing physical loads on the flood defence of the Province of Groningen along the North Sea over the next decades. This is caused by a sea level rise between 15 and 35 centimetres whilst the ground level is lowering between 38 and 48 centimetres until the year 2050. This results in salt-water intrusion into the land...

Engineering review on the final closure of Saemangeum Dike

HR Wallingford has commenced an engineering review on the Final Closure of Saemangeum Dike. This draft final report represents the completion of the second phase of studies by HR Wallingford and is issued for review by KARICO and discussion with their representatives during meetings planned in Ansan during the second week of October 2005. The...

Spatial Reconnaissance: Technical Report ComCoast

ComCoast (Combined Functions in Coastal Defence Zones) is an INTERREG IIIB project funded by the EU. ComCoast aims to develop and demonstrate innovative solutions for flood protection in coastal areas. In ComCoast, five countries from the North Sea Region are involved: Belgium, Denmark, The Netherlands, Germany, and the UK. In total, ten...

Analysis of failure situations for sea dike in Northern Vietnam and point out some suitable solutions

Failure analysis of sea dikes in the northern part of Viet Nam. Solutions to improve the present dikes in a cost efficient way.

Sea dikes northern part of Viet Nam (Red river dikes): Review

Inventory of the status of the sea dikes in the Red River Delta (northern Vietnam) partly as preparation for improvement works subsidized by the world food program.

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...
