  1. 16. Tillskottsbevattning i vårsäd : effekter på markvattenbalans och skörd

    University essay from SLU/Dept. of Soil and Environment

    Author : Åsa Larsson; [2020]
    Keywords : bevattning; markvattenmagasin; markvattenhaltsmätningar; anpassad evapotranspiration; stressfaktor; vattenhushållning;

    Abstract : Vattenbrist är den vanligaste skördebegränsande faktorn i världen och kommer sannolikt, både i Sverige och globalt öka i takt med klimatförändringarna. Samtidigt har Sverige förbundit sig till Agenda 2030 och en effektiv vattenanvändning. READ MORE

  2. 17. Modelling the water balance of a grassland soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Elvin Rufullayev; [2020]
    Keywords : calibration; high precision weighing lysimeter; numerical modelling; plant growth; potential evapotranspiration; soil processes; STELLA Architect; temperate grassland; TERENO; vadose zone; validation;

    Abstract : Expected future climate change characterized by higher temperatures and more frequent summer droughts may cause significant changes in soil hydrological processes leading to limited nutrient and water availability and reductions in plant growth. Soil hydrological and plant growth models attempt to reproduce the complex interactions in the plant-soil water system in terms of mathematical equations, parameters and coefficients. READ MORE

  3. 18. Hydrogeological assessment of springs and groundwater in Carrizal, Costa Rica

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

    Author : Markus Beckman; Jacob Sannum; [2020]
    Keywords : Hydrogeology; volcanic aquifer; Water balance analysis; MBR; Costa Rica; double ring infiltrometer; spring characteristics; minor field study.; Technology and Engineering;

    Abstract : The main purpose of this thesis is to increase the understanding of how hydrogeological conditions are affecting the local water resources in Carrizal on the Barva Volcano, Costa Rica. Hydrogeological investigations of spring characteristics, soil infiltration rates and water flow in springs and rivers were conducted at the study area in Costa Rica as part of a Minor Field Study (MFS).

  4. 19. Conceptualizing green water within the planetary boundary for freshwater use

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Arne Tobian; [2019]
    Keywords : green water; planetary boundaries; land use modelling; physical geography; ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. READ MORE

  5. 20. Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linsey Marie Avila; [2019]
    Keywords : Energy balance; energy balance closure; energy balance ratio; net radiation; sensible heat; latent heat; turbulent fluxes; ground heat flux; energy storage; available energy; Bowen ratio; evaporative fraction; latent heat of vaporization; water balance; evapotranspiration; precipitation; water storage; water discharge; gross primary production; ecosystem respiration; net ecosystem production; carbon exchange; water use efficiency; Earth and Environmental Sciences;

    Abstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.
