    Author : Anders Henriksson; [2015]
    Keywords : DTW-index; site productivity; Krycklan; remote sensing; wet-areas mapping; forest hydrology; topography; site properties; bonitet; fjärranalys; markfuktighet; kartläggning; markhydrologi; topografi; ståndortsegenskaper;

    Abstract : The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). READ MORE

  3. 2. Flow regime and land cover changesin the Didessa sub-basin of the Blue Nile River,South-Western Ethiopia : combining empirical analysis and community perception

    University essay from SLU/Dept. of Environmental Assessment

    Author : Bizuneh Sima; [2011]
    Keywords : Didessa Sub-Basin; Blue Nile ; Ethiopia; Community Perception; Forest-Hydrology;

    Abstract : Defining stream flow and rainfall patterns over a period of different land use/cover changes and understanding the community’s knowledge on changes in the natural resources of the Didessa sub-basin of the Blue Nile River were the main areas which this study dealt with. Based on the availability of hydrological data 8 out of 14 different gauged catchments of Didessa sub-basin were selected for further analysis. READ MORE

  4. 3. The effect of forest cover for the dynamics of a snowpack : linking snow water equivalents, meltwater contributions and evaporative loss

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Álvaro Valle Millán; [2010]
    Keywords : Forest hydrology; Clearcut; Snow accumulation; Snow water equivalents; Meltwater released; Evaporative loss; Water balance;

    Abstract : Forestry is one of the main economical activities in Sweden, but it can seriously affect the dynamic of the water cycle by altering several hydrological factors such as timing and amount of snow melt and meltwater contributions from the snowpack to the soil.This thesis, performed during the spring 2010 within the “Balsjö Catchment Study” in Northern Sweden, was carried out in order to understand how forest cover can influence the hydrology of snow-dominated boreal catchments.
