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

    Författare :Yoshihiro Shibuo; Georgia Destouni; Jerker Jarsjö; Clifford Voss; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Shilpa Muliyil Asokan; Georgia Destouni; Howard Wheater; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. 3. Basin-scale change in water availability and water quality under intensified irrigated agriculture

    Författare :Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Irrigation; Hydrology; Land-use change; Basin-scale; Central Asia; Aral Sea; Semi-arid; Return flow; Water saving; Health risk; Water quality; Surface water; Groundwater; Nitrogen; Attenuation; Recirculation; Climate change; Physical Geography; naturgeografi;

    Sammanfattning : Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. LÄS MER
