  1. 1. Long-Term Simulation of Coastal Evolution

    Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. 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.

  5. 4. On the long-term behaviour of tension loaded piles in natural soft soils

    Författare :Jorge Yannie; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

    Sammanfattning : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. LÄS MER

  7. 5. Long-term development of subalpine lakes : effects of nutrients, climate and hydrological variability as assessed by biological and geochemical sediment proxies

    Författare :Manuela Milan; Christian Bigler; Monica Tolotti; Richard Bindler; Krystyna Szeroczyńska; Atte Korhola; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleolimnology; diatoms; Cladocera; sub-fossil pigments; geochemistry; wavelengthdispersive X-ray fluorescence spectroscopy; Lake Garda; Lake Ledro; reference conditions; nutrient enrichment; climate change; hydrological regime.;

    Sammanfattning : Sediment records of two Italian subalpine lakes (Lake Garda and Lake Ledro) were analyzed in order to reconstruct their ecological evolution over the past several hundred years. A multi-proxy and multi-site approach was applied in order to disentangle the effects of local anthropogenic forcings, such as nutrients, and climate impacts on the two lakes and their catchments.
