1. 1. CO2-emissions from rivers and streams : Seasonal variation of pCO2-levels and CO2-fluxes

   University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

   Author : Emile Vandeburie; [2020]
   Keywords : Eddy Covariance; CO2-flux; air-water gas exchange;

   Abstract : Since the industrial evolution, the CO2-levels have been increasing in a way that’s never seen in the history of the earth. To mitigate and adapt to the happening climate change it is really important to understand the global carbon cycle and each component that plays a role in it. READ MORE

3. 2. 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.

4. 3. Urban flood modelling : a GIS based approach in Lomma, Skåne region

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Michael Araya Ghebremariam; [2017]
   Keywords : Physical Geography and Ecosystem analysis; Digital Elevation Model; Single flow direction algorithm; Deterministic eight-node D8 algorithm; Multiple flow direction algorithm; Triangular Form Based Multiple Flow algorithm TFM ; Earth and Environmental Sciences;

   Abstract : Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. READ MORE

5. 4. Investigation of groundwater resources - A case study in north-west Tanzania using remote sensing analysis and groundwater simulation

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Cecilia Lundqvist; [2017]
   Keywords : Groundwater resources; Remote sensing; Hydrologic budget; MOD- FLOW; Chonyonyo; Tanzania; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : Globally 884 million people depend on unsafe drinking water, of which 159 million depend on untreated surface water (WHO, 2017). In Tanzania 44% of the popula- tion lack access to safe drinking water (WaterAid, 2017). READ MORE

6. 5. Applicability of using ArcMap to spatially calculate and display monthly evapotranspiration rates : An investigation using government climate data in British Columbia, Canada

   University essay from Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

   Author : Margie Massier; [2012]
   Keywords : Evapotranspiration ET ; British Columbia BC ; GIS; ArcMap;

   Abstract : Evapotranspiration (ET) is the sum of the evaporation of water from the Earth’s surface and the total transpiration from plants.  Spatially calculating ET is necessary because it is a major component in quantifying a water budget, and maps provide the spatial ability to display the distribution.
