  1. 11. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexis Cazorla; [2020]
    Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

    Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

  3. 12. Hydrological modelling and flood risk in a data scarce country: Matola, Mozambique

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tanja Sellick; [2020]
    Keywords : hydrological modelling; flood hazard; TFM-DYN; climate change; Matola; Mozambique; data scarcity; pluvial flooding; flood risk.; Earth and Environmental Sciences;

    Abstract : Flooding is a frequent natural hazard globally that is capable of major damage to society. The hazard is especially prevalent in Mozambique, in which many flood events with negative effects have occurred. Disaster risk management and research is therefore important in the country. However, as a developing country, it is subject to data scarcity. READ MORE

  4. 13. Evaluation of water stress mapping methods in vineyards using airborne thermal imaging

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alon Zuta; [2020]
    Keywords : Geography; Geographical information systems; GIS; Remote sensing; Cover crop; Thermal imaging; Spatial variability; vineyards; interpolation; water stress index; CWSI; Ig; stem water potential; UAV; Rheingau; Interpolation.; Agriculture and Food Sciences; Biology and Life Sciences; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : With low cost and high efficiency, use of airborne infrared thermography imaging from an unmanned aerial vehicle (UAV) has become a widely used technique to measure plant water stress. With that, the use of UAV mounted thermal camera as a precision agriculture technique to map crop water stress is not trivial and its success is depended on variety of factors which are still needed to be studied and understood.

  5. 14. Sea Level Rise Vulnerability Assessment for Abu Dhabi, United Arab Emirates

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Marwa al Kabban; [2019]
    Keywords : Physical Geography and Ecosystem analysis; GIS; Sea Level Rise; Vulnerability Assessment; Modelling Sea Level Rise; Impacts Assessment of Sea Level Rise; GIS application in Sea Level Rise; Disaster Risk Reduction DRR ; Government Information Sharing GIS ; ArcGIS Web App Builder Dashboard; Sea Level Rise Story Map; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The phenomenon of global warming has become a fact, however; the uncertainty is about the magnitude and acceleration of its manifestations. Global mean sea level rise is one of the results induced by global warming and is happening with an undetectable accelerated pace. READ MORE

  6. 15. Development of a GIS methodology to evaluate informal urban green areas for inclusion in a community governance program

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Katalin Bunyevácz; [2019]
    Keywords : geography; GIS; informal urban green spaces; community governance; multi- criteria analysis; Earth and Environmental Sciences;

    Abstract : Informal green spaces are “small green areas” which are some square meter plots along streets or in junctions, in front of public or private buildings. Informal urban green space become or remain in neglected condition due to the lack of capacity of the municipality to maintain them. READ MORE
