  1. 1. Vattenbalansberäkningar som metod för bevattningsplanering : Efterhandsvalidering i svenska bevattningsförsök med olika bevattningsstrategier i vall

    University essay from SLU/Dept. of Soil and Environment

    Author : Carl Andås; [2023]
    Keywords : bevattning; Penman-Monteith; markvattenhaltsmätningar; evapotranspiration;

    Abstract : Bevattning för med sig många effekter som vore önskvärda i dagens svenska lantbruk, som präglas av ökade produktionsrisk till följd av höga produktionskostnader men samtidigt ökade avräkningspriser. Efterfrågan på bevattningskompetens och effektiv bevattningsplanering för att kunna hushålla med begränsade vattenresurser kan förväntas öka i vår tid. READ MORE

  3. 2. GIS, tracer test and water balance based hydrological analysis in Tarfala, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Elias Koivisto; [2022]
    Keywords : Tarfala; DEM; Tracer test; Water balance; the Arctic; Climate change; Permafrost; Glacier;

    Abstract : Current climate change poses a threat to the Arctic due to increasing temperatures, which cause the permafrost and glaciers to melt and thaw. This thesis focused on analyzing water balances in Tarfala catchment between 2000 and 2020 and using GIS as a support for tracer test results measured in Tarfala in 2021. READ MORE

  4. 3. Improved Understanding of Water Balance in the Malwathu Oya River Basin Using SWAT and Remote Sensing

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexander Fors; [2022]
    Keywords : actual evapotranspiration; Malwathu Oya; remote sensing; Sri Lanka; SWAT modelling; SWAT calibration; WaPOR; water balance; faktisk evapotranspiration; fjärranalys; Malwathu Oya; Sri Lanka; SWAT-modellering; SWAT-kalibrering; vattenbalans; WaPOR;

    Abstract : As the need for climatic data is increasing in times of climate change and water scarcity, remote sensing (RS) and hydrological modelling are ways to battle these problems, especially in data scarce areas. The actual evapotranspiration (ETa) is one of the key parameters when assessing the water balance and a good estimate of this parameter is thus of great importance. READ MORE

  5. 4. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Simon Hannus; [2021]
    Keywords : Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

    Abstract : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

  6. 5. The potential for Binding PFAS Using Biochar and Phytoremediation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Josefin Alice Maria Svensson; [2021]
    Keywords : Physical geography; ecosystem analysis; PFAS; Per-and polyfluoroalkyl substances; remediation; phytoremediation; biochar; Earth and Environmental Sciences;

    Abstract : PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. READ MORE
