1. 1. Processes of long-term coastal evolution and their mathematical modelling : Application to the Mozambican coast

   Författare :JAIME PALALANE; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coastal evolution; coastal processes; mathematical modelling; Mozambican coast; coastal erosion; Macaneta; spit model; long-term evolution;

   Sammanfattning : Different processes in response to the action of natural driven forces and the human interference on coastal systems act together, contributing to shape the coast. Coastal evolution models have been developed as useful tools to better understand the contribution of different processes on observed coastal changes, and also to anticipate future evolution in response to different actions and interventions taking place along the coast.

3. 2. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

   Författare :Li Erikson; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

4. 3. Coastal Overwash: Processes and Modelling

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

   Sammanfattning : 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. LÄS MER

5. 4. Nature-based shore protection against ship waves in intra-coastal fairways

   Författare :Björn Almström; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Naturbaserade lösningar; fartygsvågor; farleder; erosion; Furusundsleden; Naturanpassade erosionsskydd;

   Sammanfattning : Sjötrafik har alltid haft en stor betydelse för vårt samhälle genom att transportera gods och människor mellan och inom länder. Transporter till sjöss har stora fördelar associerat till relativt låga klimatutsläpp och transportkostnader. Tyvärr medför sjötrafik även en negativ påverkan på vår miljö. LÄS MER

7. 5. Sediment sources and transport pathways, Lithuanian coastal zone

   Författare :Milda Kairytè; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

   Sammanfattning : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. LÄS MER
