  1. 31. 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.

  3. 32. Optimisation of Run of River Production Forecasting Using Aiolos Forecast Studio

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Amer Al-Qes; [2020]
    Keywords : Run of river hydropower plants; power production forecasting; Aiolos forecast studio; model accuracy assessment analysis and power market.; Technology and Engineering;

    Abstract : Hydropower is simply the largest source of renewable energy in the Nordic countries, where It compose around 90% of power production in Iceland, 70% in Norway, 40% in Sweden and 20% in Finland. Mountainous terrain and abundance in the surface water is a significant contributing factor in hydropower production. READ MORE

  4. 33. Groundwater resources and vulnerability for mountain communities in the Andes

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Raheela Fahd; [2020]
    Keywords : ;

    Abstract : The purpose of the thesis is to review the effect of ongoing climate change and population growth ongroundwater resources of Katari Basin (Bolivian Andes) and the consequence of reduced groundwaterresources on the quality of water. El Alto city, situated in the Katari basin is most vulnerable to thewater shortage because of climate change and high population growth rate. READ MORE

  5. 34. Sensitivity analysis of pluvial flood modelling tools for dense urban areas : A case study in Lundby-Lindholmen, Gothenburg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Johanna Eriksson; [2020]
    Keywords : Flood Modelling; MIKE FLOOD; Sensitivity Analysis;

    Abstract : As a result of the global climate change, extreme precipitation is occurring more frequently which increases the risk of flooding, especially in urban areas. Urbanisation is widely discussed regarding urban flooding where an increase of impervious surfaces limits the infiltration and increases the surface runoff. READ MORE

  6. 35. Assessment of the Contribution of Groundwater Flow and Surface Flow from Bolmsö Island to Lake Bolmen, Sweden

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Angelique Uwera; [2020]
    Keywords : Groundwater; Surface water; GMS-MODFLOW; Bolmsö Island; Lake Bolmen; Brownification.; Technology and Engineering;

    Abstract : The increase of brownification in surface waters has been a problem for rivers and lakes from the northern hemisphere. The main factors of this water brownification are the increase of dissolved organic matter and iron in water bodies. READ MORE
