  1. 1. Changes of evapotranspiration and water cycle in China during the past decades

    Author : Ge Gao; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Potential evapotranspiration; Actual evapotranspiration; Spatial and temporal characteristic; Trend; Controlling factors; Water cycle; Thornthwaite water balance; China;

    Abstract : Evapotranspiration is the second largest quantity in the water cycle and an important indicator for climate changes. Accurate estimations and better understanding of evapotranspiration are required in hydrologic studies and water resources modelling under stationary and changing climate conditions. READ MORE

  2. 2. Changes in the Freshwater System Distinguishing Climate and Landscape Drivers

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Fernando Jaramillo; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; naturgeografi; Physical Geography;

    Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

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

    University dissertation from Stockholm : Institutionen för naturgeografi och kvartärgeologi

    Author : Yoshihiro Shibuo; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Submarine groundwater discharge; unmonitored flows; catchment hydrology; evapotranspiration; bathymetry; GIS; Aral Sea; nuclear waste repository sites; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap 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

  4. 4. Hydro-climatic changes in irrigated world regions

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Author : Shilpa Muliyil Asokan; Stockholms universitet.; [2013]
    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; naturgeografi; Physical Geography;

    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.

  5. 5. Water chemistry and runoff in forest streams at Kloten

    University dissertation from Uppsala : Uppsala universitet

    Author : Harald Grip; Uppsala universitet.; [1982]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Element clustering; evapotranspiration; impact; Hydrology; Hydrologi;

    Abstract : Natural variability of stream water composition and discharge was studied in the Kloten area, Central Sweden, by means of statistical methods and simulation technique. The effects of Urea (155 kgN ha-1) and ammonium nitrate (AN, 160 kgN ha-1) fertilization and clear-cutting were studied by comparing treated and reference streams before and after management.
