1. 1. Mapping future floods in coastal Bangladesh - Impacts of projected changes in sea level and precipitation

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Agnes Pierre; [2022]
   Nyckelord :flood modelling; TFM-DYN; sea level rise; land subsidence; extreme precipitation; tidal flooding; Earth and Environmental Sciences;

   Sammanfattning : The exposure to flooding in coastal Bangladesh is expected to increase throughout the century as a result of climate change-induced sea level rise and intensified monsoon precipitation. The current consequences of flooding include damage to infrastructure, economy, and health through inundation and saline intrusion, and are likely to affect a larger population in the future.

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

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Michael Araya Ghebremariam; [2017]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. A dynamic and spatially distributed rainfall runoff model - Developing a model for overland flow in GIS, based on a multiple flow direction algorithm

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Hampus Nilsson; [2017]
   Nyckelord :flood modelling; GIS; TFM; surface runoff; multiple flow; flow routing; Technology and Engineering;

   Sammanfattning : Climate change is expected to cause 20-25% heavier rainfall in Sweden which, in combination with the ongoing urbanization, increases the probability of flooding in urban areas. These floods may cause large infrastructural damage and economical costs. LÄS MER
