4. 2. Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

   Author : Carmen Prieto; Georgia Destouni; Vassilios Kaleris; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; Seawater intrusion; submarine groundwater discharge; coastal groundwater management; coastal zone management; temporal variability; temporal randomness; Vattenteknik; Water engineering; Vattenteknik;

   Abstract : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.

5. 3. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation

   Author : Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial aquifer; groundwater; arsenic mobilisation; geology; Meghna basin; Bangladesh; Water engineering; Vattenteknik;

   Abstract :  Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. READ MORE

6. 4. Groundwater Vulnerability Assessment to pollution in Different Soil and Rock Materials

   Abstract : The augmentation of human population regularly corresponds with change in the land cover, including expansion of urban areas, which imposes increasing the available amount of domestic and drinking water. The study area, Halabja-Saidsadiq Basin, is situated in the Northeast of Iraq and is one of the major groundwater sources of the region. READ MORE

7. 5. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua
