11. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

12. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE

13. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model
University essay from Uppsala universitet/ElektricitetsläraAbstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

14. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE

15. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. READ MORE
