  1. 1. Dam Failure Analysis of the Parteboda Hydropower Plant : A deterministic approach

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Magnus Simon Graf; [2023]
    Keywords : ;

    Abstract : Despite all the benefits a dam can provide, hundreds of years of experience have shown the destructive forces that can be unleashed by dam failure. To carry out risk management and execute mitigative measures for a dam facility, it is first necessary to assess the incremental consequences of a potential dam failure. READ MORE

  3. 2. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martin Dahlin; [2022]
    Keywords : Streamflow information; Manning s estimation; rating curve; hydrographs; Vattenföring; avbördningskurva; hydrograf; Mannings ekvation;

    Abstract : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. READ MORE

  4. 3. Developing a Rainfall-Runoff Routing Model using  Spatially Distributed Travel Times : Modelling a Cloudburst Event in an Urban Catchment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sara Ekeroth; [2022]
    Keywords : Excess rainfall; Runoff routing; Cloud burst; Pluvials; GIS; ArcPy; Effektiv nederbörd; Avrinningsmodell; Skyfall; Pluviala översvämningar; Geodata; ArcPy;

    Abstract : The future holds challenges for urban areas when it comes to handling pluvial floodings, occurring when the rainfall intensity exceeds both the man-made and natural infiltration and drainage capacity. To gain understanding of the effects and needed measures, tools for modelling the urban response to events such as cloudbursts are needed. READ MORE

  5. 4. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lone Mokkenstorm; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Early Warning; Riverine Floods; Humanitarian Work; Impact-based Forecasting; Malawi; Earth and Environmental Sciences;

    Abstract : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.

  6. 5. A GIS-Based Method of Deriving Spatially Distributed Unit Hydrographs

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ann-Sofi Lenander; [2021]
    Keywords : the unit hydrograph; GIS; ArcPy; design storm; SCS-CN method; spatial data; excess rainfall; enhetshydrografen; GIS; Arcpy; design regn; SCS-CN metoden; geodata; effektivt regn;

    Abstract : Prior to using hydraulic and spatially distributed modelling softwares, the theory of the unit hydrograph was a commonly used tool for modelling of surface and runoff water. While distributed models often provide detailed results from extensive calculation durations, the unit hydrograph have been questioned for simplifying the physical characteristics of the watershed modelled.
