  1. 1. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilía Sól Gudgeirsdóttir; [2023]
    Keywords : SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Abstract : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. READ MORE

  3. 2. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Oskar Ahlstedt; [2022]
    Keywords : Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Abstract : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. READ MORE

  4. 3. Twenty-First Century Drought Projections in Swedish Catchments

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elise Jonsson; [2022]
    Keywords : Drought; climate change; drought index; climate models; catchments; societal functions; Torka; klimatförändring; torkindex; klimatmodeller; avrinningsområde; samhällsfunktioner;

    Abstract : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. READ MORE

  5. 4. Hydrological modelling and flood risk in a data scarce country: Matola, Mozambique

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tanja Sellick; [2020]
    Keywords : hydrological modelling; flood hazard; TFM-DYN; climate change; Matola; Mozambique; data scarcity; pluvial flooding; flood risk.; Earth and Environmental Sciences;

    Abstract : Flooding is a frequent natural hazard globally that is capable of major damage to society. The hazard is especially prevalent in Mozambique, in which many flood events with negative effects have occurred. Disaster risk management and research is therefore important in the country. However, as a developing country, it is subject to data scarcity. READ MORE
