  1. 1. Risk mapping of phosphorus leakage - improved method using a Digital Elevation Model

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Hanna Ekström; [2018]
    Nyckelord :surface runoff; erosion; phosphorus leakage; agriculture; sinks; Earth and Environmental Sciences;

    Sammanfattning : Eutrophication is an ongoing problem in the Baltic Sea and is therefore found as a topic of the Baltic Sea Action Plan as well as the environmental goals of Sweden. One source to eutrophication is the leakage of phosphorus from agricultural lands. LÄS MER

  2. 2. Global satellite data as proxies for urbanization in flood prone areas

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Florian van Schaik; [2018]
    Nyckelord :flood exposure; global satellite data; urbanization; remote sensing; sustainable development;

    Sammanfattning : Delta regions are typically characterized by their high population density, low elevation, and risk of flooding. Long term planning and preparation is needed to mitigate the adverse effects of floods. LÄS MER

  3. 3. Evaluation of digital terrain models created in post processing software for UAS-data : Focused on point clouds created through block adjustment and dense image matching

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS; Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Sabina Assefha; Matilda Sandell; [2018]
    Nyckelord :UAS; DTM; Pix4D; UAS Master; Block adjustment; Photogrammetry; UAS; DTM; Pix4D; UAS Master; Blockutjämning; Fotogrammetri;

    Sammanfattning : Lately Unmanned Aerial Systems (UAS) are used more frequently in surveying. With broader use comes higher demands on the uncertainty in such measurements. The post processing software is an important factor that affects the uncertainty in the finished product. LÄS MER

  4. 4. Interpolation of temperature data for improved weather forecasts

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Frida Cronqvist; [2018]
    Nyckelord :;

    Sammanfattning : To create weather forecasts at the Swedish Meteorological and Hydrological Institute (SMHI), it is needed to interpolate the temperature from the observation stations into a grid with 2.5 km between each point. Since the observed temperatures are known and without error, they should be held fix even after the interpolation. LÄS MER

  5. 5. Coastal erosion in Ängelholm : a case study tracking recent and historical changes to Vejbystrand

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Anna Hamilton; [2018]
    Nyckelord :coastal erosion; Ängelholm; coastal topography; DSAS; change detection; frequent storms; climate change; Earth and Environmental Sciences;

    Sammanfattning : As global warming continues to change the global climate, extreme weather events become more common. The effects of such events vary regionally due to both natural and anthropo- genic influences. This study identifies the main mechanisms causing coastal erosion in Äng- elholm and evaluates the adaptation measures implemented by the municipality. LÄS MER
