2. 1. Modelling Hydrological and Hydrodynamic Processes in Lake Tana Basin, Ethiopia

   Author : Shimelis Gebriye Setegn; Bijan Dargahi; Nicola Fohrer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Tana; Climate Change; SWAT; Hydrological Modeling; Hydrodynamic; GEMSS; MCE; Streamflow; Sediment yield; Hydrology; Hydrologi; Water engineering; Vattenteknik;

   Abstract : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. READ MORE

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

   Author : Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
   Keywords : 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

5. 3. Hydrogeological and geochemical assessment of aquifer systems with geogenic arsenic in Southeastern Bangladesh : Targeting low arsenic aquifers for safe drinking water supplies in Matlab

   Author : Mattias von Brömssen; Prosun Bhattacharya; David Polya; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arsenic; Bangladesh; drinking water; groundwater; sustainability; geochemistry; hydrogeology; modelling;

   Abstract : Naturally occurring arsenic (As) in Holocene aquifers in Bangladesh have undermined a long success of supplying the population with safe drinking water. Arsenic is mobilised in reducing environments through reductive dissolution of Fe(III)-oxyhydroxides. READ MORE

6. 4. Floodwater harvesting for artificial recharge of groundwater - estimation and prediction for arid Iran

   Author : Hossein Hashemi; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial recharge; Groundwater modeling; Climate change; Spate irrigation; Arid area; FWS; GBP;

   Abstract : Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. READ MORE

7. 5. Arsenic Geochemistry in the Alluvial Aquifers of West Bengal, India : Implications for targeting safe aquifers for sustainable drinking water supply

   Author : Ashis Biswas; Prosun Bhattacharya; Laurent Charlet; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bengal Basin; Groundwater; Arsenic; Redox processes; Competing ions; Sustainable drinking water Supply;

   Abstract : The natural occurrences of high (>10 μg/L) dissolved arsenic (As) in groundwater of Bengal Basin has put millions of people under the threat of chronic As exposure through drinking water. Present study has examined the processes that regulate As mobilization and its distribution in shallow aquifers and the potentiality of finding safe aquifers within shallow depth (. READ MORE
