Groundwater from different stations of Satkhira Municipality has been analyzed for assessing the chemistry, source rock evolution and quality. The parameter analyzed are pH, TDS, EC, Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, SO42-, PO43-, H4SiO42-, F-, I- and NO2-N. The Na+/ (Na++Ca2+) weight ratio against TDS shows that the waters are derived from Rock weathering however few samples suggests dominance of Evaporation crystallization process. Source rock deduction suggests that the aquifer is mostly carbonate weathering where also cation exchange occurred; Piper diagram suggests that...

This volume covers the floods of the major rivers of the Ganga-Brahmaputra-Meghna (GBM) Delta, and storm surge related coastal floods in these regions. The book is dedicated to addressing floods from an integrated physical-social perspective to provide students and researchers with a holistic understanding of floods in terms of both human and geomorphological aspects. The systematic coverage of all the major rivers and coastal areas in the GBM delta and surrounding regions will foster a clear comprehension of this dense reservoir of population, where thousands of people are impacted every...
