  1. 16. Rainfall-Runoff Simulation and Modelling Using HEC-HMS and HEC-RAS Models: Case Studies from Nepal and Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Jeevika Khadka; Jagritee Bhaukajee; [2018]
    Keywords : HEC-HMS; HEC-RAS; Kankai; Kävlinge; Rainfall Runoff; Flood Inundation; Modelling; Technology and Engineering;

    Abstract : Floods are probably the most frequent, widespread and disastrous hazards of the world. Almost every year, Sweden and Nepal are affected by floods though their nature and impact differs due to complete different geographical and hydrological setting. READ MORE

  3. 17. Satellite derived data to support flood modelling : An application to the Po River

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Victor Alejandro Ortiz Peña; Milos Dinic; [2018]
    Keywords : Hydraulic Modelling; Flood Modelling; HEC-RAS; Mannings Coefficient; DEM; LiDAR; SRTM; Virtual Stations;

    Abstract : Satellite derived data has become an essential input in hydraulic modelling. Digital ElevationModels (DEMs) derived from different sources through remote sensing techniques have become a powerful tool for poorly gauged regions. READ MORE

  4. 18. Frequency regulation and its effects on fish stranding : A hydrological modelling example of a Swedish river

    University essay from KTH/Industriell ekologi

    Author : Johanna Ewertzh; [2017]
    Keywords : ;

    Abstract : This is a master thesis aiming to answer how frequency regulation at a specific hydropower plant affect the risk of stranding for two common Swedish fish species: Trout and Grayling (Salmo trutta and Thymallus thymallus). The study comprises a literature review and a hydrological modelling in primarily Hec-Ras. READ MORE

  5. 19. Flood Mapping: Assessing the uncertainty associated with flood inundation modelling. A case study of the Mora River, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Isabelle Åberg; [2017]
    Keywords : Flood inundation modeling; hydraulic modeling; HEC-RAS; översvämningskartering; hydraulisk modellering; HEC-RAS;

    Abstract : Expansion of cities and major infrastructure projects lead to changes in land use and river flows. The probability of flooding is expected to increase in the future as a result of these changes in combination with climate change. READ MORE

  6. 20. Potentials and limitations of 1D, 2D and coupled 1D-2D flood modelling in HEC-RAS

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Alexander Betsholtz; Beatrice Nordlöf; [2017]
    Keywords : Hydraulic modelling; HEC-RAS; 1D; 2D; 1D-2D; flooding; sub-grid; Technology and Engineering;

    Abstract : Hydraulic models can be used to predict the consequences of flooding events. In this project, three hydraulic models were constructed using the software HEC-RAS, and compared through a case study on Höje river catchment. READ MORE
