  3. 2. 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

  4. 3. Urban flood modelling : a GIS based approach in Lomma, Skåne region

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Michael Araya Ghebremariam; [2017]
    Keywords : Physical Geography and Ecosystem analysis; Digital Elevation Model; Single flow direction algorithm; Deterministic eight-node D8 algorithm; Multiple flow direction algorithm; Triangular Form Based Multiple Flow algorithm TFM ; Earth and Environmental Sciences;

    Abstract : Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. READ MORE

  5. 4. Eastern oyster aquaculture : estuarine remediation via site suitability and spatially explicit carrying capacity modeling in Virginia’s Chesapeake Bay

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Daniel Taylor; [2013]
    Keywords : oyster; eutrophication; aquaculture; physical geography and ecosystem analysis; GIS; shellfish; MCE; Chesapeake Bay; environmental modeling; Earth and Environmental Sciences;

    Abstract : Scientific summary Estuarine eutrophication, the systemic limitation of dissolved oxygen in a body of water, has been increasingly monitored and scrutinized as an environmental concern needing acute and long term remediation efforts. The driving factors of eutrophication are largely attributed to anthropogenic sources within the watershed, sources that are products of modern civilization. READ MORE
