  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 Gendered Approach to Understanding Salinity Intrusion Impacts: A Case Study on a Coastal Region of Bangladesh

    Master-uppsats, Lunds universitet/Sociologi; Lunds universitet/Sociologiska institutionen

    Författare :Dilafroze Khanam; [2021]
    Nyckelord :Climate change; Salinity intrusion; Gender roles; Social insecurities; Gender equality; Social Sciences;

    Sammanfattning : This study sheds light on the salinity-induced social insecurities of coastal women and adolescent girls of Bangladesh and shows how salinity contributes to creating and intensifying those insecurities. Moreover, the study explores the gendered division of labor and shows how coastal females’ gender roles are accelerating to their deprivation and disadvantaged situation. LÄS MER

  4. 3. Stigande havsnivåers påverkan på hotade groddjur

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Linn Andersson; [2017]
    Nyckelord :havsnivåhöjning; klimatförändringar; kustnära habitat; groddjur; bevarandearbete; naturvård; GIS; Earth and Environmental Sciences;

    Sammanfattning : Climate change and biodiversity loss are two of the major challenges of our time, and are strongly interconnected. Sea level rise is a consequence of these and a significant threat to global coastal habitats. LÄS MER

  5. 4. Numerical Simulation of Saltwater Intrusion Caused by Land-Use Change and Groundwater Pumping in a Salinity-Affected Coastal Aquifer, Japan

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Keisuke Konishi; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Lowering of groundwater level may cause saltwater intrusion in coastal aquifers. Since decrease in groundwater recharge rate and overpumping lower groundwater level, recharge rate and pumping rate are main factors of saltwater intrusion In the study area, the land-use has been changing since a university campus was newly constructed.

  7. 5. Climate change adaptation practices in agriculture : A case study on coastal and drought prone areas of Bangladesh

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Tariq-Ul-Hassan Khan; [2015]
    Nyckelord :climate change; agriculture; coastal area; drought prone area; adaptation; local practice; Bangladesh;

    Sammanfattning : Historically Bangladesh is a breeding ground for different climatic disasters due to its geographical location and the impacts are huge due to economic condition, high intensity of exposed population and dependency on nature. Climate change is causing an increase in the intensity and frequency of natural disasters. LÄS MER
