2. 1. Hydro-climatic changes in irrigated world regions

   Author : Shilpa Muliyil Asokan; Georgia Destouni; Howard Wheater; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; hydro-climatic change; evapotranspiration; irrigation; water demand; water balance; land-use; water-use; hydrological catchment; Aral Sea; India; Mahanadi River Basin; Physical Geography; naturgeografi;

   Abstract : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

4. 2. Modelling water and solute flows at land-sea and land-atmosphere interfaces under data limitations

   Author : Yoshihiro Shibuo; Georgia Destouni; Jerker Jarsjö; Clifford Voss; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Submarine groundwater discharge; unmonitored flows; catchment hydrology; evapotranspiration; bathymetry; GIS; Aral Sea; nuclear waste repository sites; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Abstract : Water and vapour flows from land to sea and the atmosphere are important for water resources, coastal ecosystems and climate. This thesis investigates possible methods for modelling these flows under often encountered unmonitored hydrological conditions and data limitations. READ MORE

5. 3. Modeling the Seasonality of Carbon, Evapotranspiration and Heat Processes for Cold Climate Conditions

   Author : Sihong Wu; Per-Erik Jansson; Andreas Ibröm; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; net ecosystem exchange NEE ; sensible and latent heat fluxes; photosynthesis; respiration; nitrogen turnover; Scots pine forest; bare soil; cold climate; soil physical characteristics; CoupModel; GLUE; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

   Abstract : The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. READ MORE

6. 4. The value of experimental data and modelling for exploration of hydrological functioning: The case of a till hillslope

   Author : Nino Amvrosiadi; Jan Seibert; Kevin Bishop; Keith Beven; April James; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Successfully modeling one system response (e.g. hydrograph or solute transport) sometimes gives the false sense of well-characterizing the modeled system. This is partly because of the well-known equifinality issue; during the calibration process multiple parameter combinations can produce similarly good results. READ MORE

7. 5. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

   Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. READ MORE
