  1. 1. Environmental history in southern Mozambique Reconstruction of flooding events, hydroclimate and sea-level dynamics since mid-Holocene

    Detta är en avhandling från Stockholm : Department of Physical Geography, Stockholm University

    Författare :Sandra Raúl Sitoe; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Southern Africa; Limpopo River floodplain; flooding event; sea-level change; climate change; diatoms; phytoliths; mineral magnetics; grain-size; radiocarbon dating; Quaternary Geology; kvartärgeologi;

    Sammanfattning : The aim of this thesis has been to reconstruct paleoenvironment, paleohydrology and paleoclimate in coastal southern Mozambique, with emphasis on tracing past flooding events on the lower Limpopo River floodplain. In order to extend flood chronologies beyond periods covered by instrumental data, sediments from lakes on the floodplain were studied (Lake Lungué, Coassane Oxbow, Lake Magandane and Lake Soane).

  2. 2. Climate in the eastern Mediterranean during the Holocene and beyond – A Peloponnesian perspective

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Martin Finné; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; stalagmites; climate variability; flooding history; eastern Mediterranean; southern Greece; Holocene; Pleistocene; naturgeografi; Physical Geography;

    Sammanfattning : This thesis contributes increased knowledge about climate variability during the late Quaternary in the eastern Mediterranean. Results from a paleoclimate review reveal that regional wetter conditions from 6000 to 5400 years BP were replaced by a less wet period from 5400 to 4600 years BP and to fully arid conditions around 4600 years BP.

  3. 3. Flood Hazard Assessment in Data-Scarce Basins Use of alternative data and modelling techniques

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Diana Fuentes-Andino; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; floods; data scarcity; data quality; uncertainty analysis; regionalisation; flood frequency analysis; GLUE; hydraulic modelling; rainfall-runoff modeling; TOPMODEL; LISFLOOD-FP; GRADEX; index-flood; Muskingum-Cunge-Todini flow routing; Mellanamerika; högflöde; datakvalitet; osäkerhetsanalys; regionalisering; frekvensanalys av högflöden; GLUE; hydraulisk modellering; nederbörds-avrinningsmodeller; TOPMODEL; LISFLOOD-FP; GRADEX; indexflöde; Muskingum-Cunge-Todini flödessvarstid; Central América; inundaciones; escasez de datos; calidad de los datos; análisis de incertidumbre; regionalización; análisis de frequencia de inundación; GLUE; modelación hidraulica; modelo de lluvia-escorrentía; TOPMODEL; LISFLOOD-FP; GRADEX; índice de inundación; Muskingum-Cunge-Todini rutina de propagación de flujo;

    Sammanfattning : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. LÄS MER

  4. 4. Managing knowledge sharing of extreme weather induced impacts on land transport infrastructure Case study of the Swedish Transport Administration

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Monika Rydstedt Nyman; Karlstads universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lessons learned; risk management; climate change adaptation; accident investigation method; extreme weather events; natural hazard; land transport infrastructure; maintenance; lärande; kunskapsåterföring; risk hantering; klimatanpassning; olycksutredningsmetod; naturolyckor; landtransport infrastruktur; underhåll; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : Extreme weather events and effects of climate change are threats to the transport sector’s functionality and safety. Risk management in this context implies a necessity to focus on the connection between near-term experiences and coping strategies on one hand, and long-term adaptation analyses on the other.

  5. 5. Organizational Lessons Learned Natural Hazards Affecting Critical Infrastructure

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Monika Rydstedt Nyman; Karlstads universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural hazards; critical infrastructure; feedback; lessons learned; collective learning; memory building; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : This thesis focuses on an issue often presented as a solution – albeit a debated one ­– namely learning, specifically lessons learned from natural hazard events. Empirically, this thesis examines flooding and avalanches in a Swedish context, centering on systematic feedback mechanisms and learning from extreme events. LÄS MER
