1. 1. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Carl Holmquist; [2023]
   Keywords : Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

   Abstract : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. READ MORE

3. 2. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project

   University essay from KTH/Jord- och bergmekanik

   Author : Ida Schjelderup; [2022]
   Keywords : Jet grouting; jet grout bottom plug; cut-and-cover tunnel; tunnel design;

   Abstract : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. READ MORE

4. 3. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ainahu Abdul Hamid; [2021]
   Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

   Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE

5. 4. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
   Keywords : HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

   Abstract : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

6. 5. Life and fracture in very high cycle fatigue of a high strength steel

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Daniel Karlsson; [2021]
   Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

   Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE
