1. 21. Effectiveness of Barrier Well by Pumping Ratio Control for Saltwater Intrusion: Lab-Scale Experiments and Numerical Modeling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Shinichi Ozaki; [2021]
   Keywords : Saltwater intrusion; Barrier well; Pumping ratio control; Production well; salinity-affected coastal aquifer; Critical groundwater pumping ratio; Technology and Engineering;

   Abstract : Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. READ MORE

3. 22. Antibiotic resistance in Streptococcus agalactiae isolates from dairy camels in Kenya

   University essay from SLU/Dept. of Clinical Sciences

   Author : Emelie Lejon Flodin; [2021]
   Keywords : GBS; Camelus dromedarius; tetracycline resistance; mastitis; milk; pastoralist;

   Abstract : Camels (Camelus dromedarius) are the most valuable livestock species in the arid and semi-arid lands in the Horn of Africa where the majority of the human population adopts a pastoralist lifestyle with extensive animal husbandry. Camels provide an important food source, milk, which is considered to be the most important commodity, and a source of income for the pastoralists. READ MORE

4. 23. Cooling Oasis

   University essay from KTH/Arkitektur

   Author : Lejla Rizvani; [2021]
   Keywords : Dubai; UHI; UAE; heat; shade; cooling; factor; sun; desert; climate; temperature; vegetation;

   Abstract : The urban heat island, UHI, is a phenomenon that occurs in all cities. This phenomenon is an effect of us humans and the environments we have built. What happens in cities are that they re-emit the suns heat and other energies trapping them in this heat island. READ MORE

5. 24. A Laboratory-Scale Examination to Find an Optimal Application for a Groundwater Barrier Well

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Tatsuya Nagino; [2021]
   Keywords : Groundwater; Seawater intrusion; Countermeasure; Negative hydraulic barrier; Sea level rise; Coastal aquifer; Technology and Engineering;

   Abstract : Seawater intrusion has been aggravated due to anthropogenic reasons, such as sea level rise and over abstraction of groundwater, which is spoiling the groundwater sustainability. This study focused on a negative hydraulic barrier using a barrier well as a countermeasure. READ MORE

6. 25. Exploring Spatiotemporal Relationships between InSAR-derived Land Subsidence and Satellite-based Hydrological Variables

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Yixin Zhang; [2021]
   Keywords : InSAR; Shabestar; subsidence; groundwater; hydrological variables; LSTM; Sentinel-1A; Geomatics; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : Shabestar basin in the East Azerbaijan province, Northwest Iran, where irrigation is the main groundwater consumer, has experienced large-scale subsidence and groundwater deletion, which poses a threat to the local agricultural activities, economic development, and food security. With the emergency of mitigating the risk, satisfying future demand for groundwater, and improving resilience considering climate change, this study proposes a satellite-based approach to explore the spatio-temporal relationships between measured subsidence and hydrological variables in the basin to assist groundwater management strategy.
