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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

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

    Sammanfattning : 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. LÄS MER

  3. 17. Effects of afforestation and crop systems on the water balance in the highlands of Ethiopia

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Rebecca Naomi Ter Borg; [2020]
    Nyckelord :Acacia decurrens; landscape water balance; sediment yield; soil and water conservation; SWAT modelling; water balance partitioning;

    Sammanfattning : In the Upper Blue Nile Basin land use is rapidly changing due to agricultural development and intensification with potential effects on the water availability both up- and downstream. This study is aimed to explore the impact of agricultural land use change on a landscape water balance. LÄS MER

  4. 18. Tillskottsbevattning i vårsäd : effekter på markvattenbalans och skörd

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Åsa Larsson; [2020]
    Nyckelord :bevattning; markvattenmagasin; markvattenhaltsmätningar; anpassad evapotranspiration; stressfaktor; vattenhushållning;

    Sammanfattning : 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. LÄS MER

  5. 19. Modelling the water balance of a grassland soil

    Master-uppsats, SLU/Dept. of Soil and Environment

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

    Sammanfattning : 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. LÄS MER

  7. 20. Hydrogeological assessment of springs and groundwater in Carrizal, Costa Rica

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

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

    Sammanfattning : 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).
