Spatial Modeling of Environmental Pollution and Ecological Risk
provides valuable information and insights for researchers,
students and professionals in geography, hydrology, sedimentology,
soil science, agriculture, engineering and GIS as they face
increasingly complex challenges around development strategies for a
sustainable society. Written by the world’s leading researchers
in their field, each article will begin with a short introductory
essay that includes an overview of the sections' papers. Individual
chapters focus on the core themes of research and knowledge and
some topics that have received lesser attention. Each chapter will
review the current understanding of knowledge regarding the present
study and scope and consider where future efforts should be
directed.
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 year due to flood hazards
and agricultural destabilization. This comprehensive treatment of
flood issues in the region covers flash floods, fluvial floods,
fluvio-tidal floods, and coastal floods, and outlines flood
management strategies to maintain ecological integrity and
environmental stability, and prevent harmful impacts of future
floods. The book is intended for students and researchers in earth
and environmental sciences, especially geomorphology, hydrology,
geography, geology, natural resources management, and regional
planning.
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 the
northwestern aquifers are in temporary hard and fresh in nature;
southeastern aquifers are mixed in character and has tendency to
shift to permanently hard water and southern aquifers are
influenced by saline water and moderately hard in nature. With
reference to Bangladesh and WHO standard this research states that
most ground water are qualified for drinking purposes; however
management options to be formulated for further exploitation.
