2. 21. Coastal Overwash: Processes and Modelling

   Author : Chantal Donnelly; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overwash; washover; hurricane impacts; dune erosion; barrier islands;

   Abstract : Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. READ MORE

4. 22. Long-term beach and dune evolution : Development and application of the CS-model

   Author : Caroline Hallin; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coastal processes; sediment transport; numerical modelling; Ängelholm Beach; Kennemer Dunes;

   Abstract : Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. READ MORE

5. 23. Long-Term Simulation of Coastal Evolution

   Author : Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

   Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

6. 24. Simulation of Irregular Waves and Wave Induced Loads on Wind Power Plants in Shallow Water

   Author : Jenny Trumars; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave load; Non-linear wave models; ocean engineering; wind energy converter; perturbation theory; shallow water;

   Abstract : The essay gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. READ MORE

7. 25. Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves

   Author : Mohsen Irannezhad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nominal wake; Resistance; CFD; RANS; FNPF; Regular head waves; Ship motions;

   Abstract : In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power. READ MORE
