TAILIEUCHUNG - Summary of doctoral dissertation: Wave Overtopping at sea dikes with crown-walls in the northern coastal delta of Vietnam

The thesis aims to investigate the influence of low crown-walls on overtopping discharge and the behaviour of overtopping flow at sea dikes. By doing so, the reliability of overtopping estimation is increased to improve the dike design guidelines currently applied in Viet Nam. | MINISTRY OF EDUCATION AND MINISTRY OF AGRICULTURE TRAINING AND RURAL DEVELOPMENT WATER RESOURCES UNIVERSITY NGUYEN VAN THIN WAVE OVERTOPPING AT SEA DIKES WITH CROWNN-WALLS IN THE NORTHERN COASTAL DELTA OF VIETNAM Specialization Hydraulic Engineering Code No 62-58-40-01 SUMMARY OF DOCTORAL DISSERTATION HA NOI 2014 This scientific work has been accomplished at Water Resources University Advisor 1 Assoc.

Rationale Viet Nam is a nation that is seriously affected by climate change and sea level raise. There are many centres of economy and culture along the coastline. In the north sea dikes are relatively low with narrow crests steep seaward and landward slopes most dikes are directly exposed to wave attack. Historical records show that wave overtopping often causes damage to dike crests and landward slopes. One of the effective measures to reduce overtopping is the use of low crown-walls because heightening dikes or constructing outer berms are costly and not feasible especially dikes with narrow margins. Till now studies into the influence of low crown-walls and interaction between wave-wall and overtopping are limited. A better understanding of the influence of crown-walls and promenade on overtopping is necessary to improve the present dike design guidelines in Viet Nam. These facts lend the foundation for this thesis that is to investigate Wave Overtopping at sea dikes with crown-walls in the northern coastal delta of Vietnam . 2. Research objectives The thesis aims to investigate the influence of low crown-walls on overtopping discharge and the behaviour of overtopping flow at sea dikes. By .
