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

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

   Sammanfattning : 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. LÄS MER

4. 3. Effects of Salinization on Lake Metabolism

   Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Författare :Emil Nordström; [2020]
   Nyckelord :Freshwater ecology; carbon flux; mesocosms; diurnal variation;

   Sammanfattning : With rising salinity levels in many freshwaters across the globe caused by for example sealevel rise and de-icing salts, it becomes important to understand what effect it has on freshwater ecosystems, since the lakes and rivers themselves are important parts in the global carbon cycle. In this study I have looked at what effects increased salinity levels have on different lakes metabolism, specifically oxygen concentration and primary production. LÄS MER

5. 4. Aquifer Thermal Energy Storage : Impact on grondwater chemistry

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Julian Kolesnik Lindgren; [2018]
   Nyckelord :ATES; Aquifer Thermal Energy Storage; groundwater chemistry; akviferlager; akviferlagring; termisk energilagring; grundvattenkemi;

   Sammanfattning : Groundwater is potentially a useful source for storing and providing thermal energy to the built environment. In a nordic context, aquifer thermal energy storage, (ATES) has not been subject to a wider extent of research concerning environmental impact. LÄS MER
