  1. 1. Watershed delineation for runoff estimations to culverts in the Swedish road network : a comparison between two GIS based hydrological modelling methods and a manually delineated watershed

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iris Behrens; [2017]
    Keywords : GIS; hydrological modelling; watershed: single flow direction algorithm; multiple flow direction algorithm; climate change adaption; Earth and Environmental Sciences;

    Abstract : The anticipated climate changes are predicted to alter the precipitation patterns in Sweden. Increased episodes of intense short-duration rainfall and higher intensities of day long-duration rainfall are expected. Road sections are often a target of flooding, causing impassable roads, due to the lack of capacity of drainage systems. READ MORE

  2. 2. Spatial runner : environmental and musical exposure effects on runners through an idealized routing network

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Leif Kuhre-Holmquist; [2017]
    Keywords : Traveling Salesman Problem; Physical Geography and Ecosystem Science; turn-restriction algorithm; GRVI; exercise; geomatics; Earth and Environmental Sciences;

    Abstract : Physical activities such as running have previously been proven to be positive on the health of individuals who partake in such activities. Further studies have separately analyzed the positive benefits of natural environments, such as forests, and positive effects of music on runners. READ MORE

  3. 3. Hydrology and surface water chemistry in a small forested catchment : which factors influence surface water acidity?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maja Jensen; [2017]
    Keywords : Physical geography; ecosystem analysis; hydrology; surface water chemistry; acidification; deposition; water balance modelling; Earth and Environmental Sciences;

    Abstract : Water chemistry alterations such as acidification and eutrophication represent major threats to the running waters of the world, and Swedish waters are among the most vulnerable. In this study the small forested catchment Storskogen, part of the SWETHRO monitoring network, was analysed to examine the links between deposition, catchment hydrological properties and surface water chemistry.

  4. 4. A review on ozonation and17a-ethinylestradiol - formation and effects in the environment of the by-products

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Erica Svensson; [2017]
    Keywords : Ethinylestradiol; EE2; By-products; Ozonation products; Transformation products; Ozonation; Earth and Environmental Sciences;

    Abstract : Today, waste water treatment plants do not remove pharmaceutical residues from the water (as there are currently no regulations for wastewater treatment in regards to pharmaceuticals residues in Sweden) resulting in a high concentration of pharmaceuticals reaching the environment. The Swedish environmental protection agency have recently concluded that there is a need for advanced treatment of pharmaceuticals in wastewater. READ MORE

  5. 5. Sensitivity analysis and calibration of multi energy balance land surface model parameters

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kim Friberg; [2017]
    Keywords : Physical Geography; Land Surface Model; Multi Energy Balance; Sensitivity Analysis; Parameter Calibration; Earth and Environmental Sciences;

    Abstract : Flows of energy between the atmosphere, the oceans and the land surfaces drive weather and climate on Earth. Increased understanding of these processes is crucial to successfully predict and address the challenges of climate change. READ MORE
