Combined Analysis Of Tide- And Wave-Induced Water Table Fluctuations For Structural Characterization Of A Coastal Aquifer, Victoria A. Trglavcnik
Electronic Thesis and Dissertation Repository
Understanding of coastal hydrogeology is essential for the assessment, management, and protection of coastal groundwater resources. Coastal groundwater is often an important source of drinking water for coastal communities but can be contaminated by saltwater or human-derived contaminants. The groundwater table in coastal aquifers fluctuates in response to various oceanic pressure forces acting at the shoreline, including tides, individual waves, and offshore storms. Measurements of water table fluctuations in response to tides and waves can be used to characterize coastal aquifers and provide important insight into the hydraulic properties and structure, including the connectivity between the aquifer and ocean. Most …

Numerical Evaluation Of Community-Scale Aquifer Storage, Transfer And Recovery Technology, Jessica Barker
Electronic Thesis and Dissertation Repository
Communities in the coastal regions of south-western Bangladesh currently experience severe seasonal water scarcity and groundwater sources of unsuitable salinity. Aquifer storage, transfer and recovery (ASTR), using a seasonal surplus of potable water, is being tested as a potential low-cost (less than $8000 USD) water supply alternative for these communities. A variable-density numerical groundwater model was developed to investigate the engineering technical feasibility of small-scale ASTR systems for the coastal communities in Bangladesh and specifically to support future field site selection and system design. The numerical model was calibrated based on an existing ASTR site and applied to explore the …
