  1. 6. Remote sensing-based monitoring of snow cover dynamics and its influence on vegetation growth in the Middle Atlas Mountains

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nezha Acil; [2016]
    Keywords : grasslands; shrublands; forests; Morocco; mountains; monitoring; remote sensing; MODIS; snow; vegetation; Physical Geography; Ecosystem analysis; GIS; Earth and Environmental Sciences;

    Abstract : Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this effect by comparing snow-fed and non-snow-fed sites.

  3. 7. Environmental Controls on Snow Cover Thickness and Water Equivalent in Two Sub-Arctic Mountain Catchments

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christopher Cosgrove; [2015]
    Keywords : Snow; hydrology; sub-Arctic; mountains; climate; landscape;

    Abstract : The spatial variability of snow cover characteristics (depth, density, and snow water equivalent [SWE]) has paramount importance for the management of water resources in mountain environments. Passive microwave (PM) inference of SWE from space-borne instrumentation is increasingly used but the reliability of this technique remains limited in mountainous areas. READ MORE

  4. 8. Energy and hydrology modelling of hydropower in Eastern Canada

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mimmi Ljungberg; [2015]
    Keywords : Rainfall runoff model; hydropower; Eastern Canada; electricity market; Technology and Engineering;

    Abstract : Kanada är väldigt rikt på energiresurser och fjärde största vattenkraftproducenten i världen. Provinsen Quebec står för omkring 52% av Kanadas totala vattenkraftsproduktion, och ener- gimarknaden Quebec domineras fullständigt av vattenkraft: 96% av elen genereras där av vattenkraft.

  5. 9. Atmospheric mercury deposition in alpine snow, northern British Columbia and southwestern Yukon, Canada

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pia Karlsson; [2014]
    Keywords : ;

    Abstract : High mercury (Hg) levels have been measured in fish in Kusawa Lake (KL), a subalpine, partly glacier-fed lake situated in the southwestern Yukon, Canada, but it is presently unknown where this Hg comes from. One possible source may be atmospheric deposition of Hg in snow and subsequent release by melt into the lake. READ MORE

  6. 10. Investigations of manual and satellite observations of snow in Järämä (North Sweden)

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Daniel Pinto; [2013]
    Keywords : Satellite; Järämä; snow albedo; surface reflectance; snowpack; snow grain size; snow hardness; weather observation; reindeers grazing;

    Abstract : The snow cover plays an important role not only for the whole climate system but also for tourism and economy in the Lapland winter (e.g. dog sledding, snow mobile, etc). READ MORE
