Worldwide demand for sand and gravel is increasing daily, as the
need for these materials continues to rise, for example in the
construction sector, in land filling and for transportation sector
based infrastructural projects. This results in over-extraction of
sand from channel beds, and hampers the natural renewal of
sediment, geological setup and morphological processes of the
riverine system. In India, illegal sand mining (of alluvial
channels) and gravel mining (of perennial channels) are two
anthropogenic issues that negatively affect the sustainable
drainage system. Along the Kangsabati River in India, the
consequences of sand mining are very serious. The construction of
Mukutmonipur Dam (1958) on the river causes huge sediment
deposition along the middle and downstream areas, these same areas
are also intensely mined for sand (instream and on the flood
plain). Geospatial models are applied in order to better understand
the state and the resilience of stream hydraulics, morphological
and river ecosystem variables during pre-mining and post-mining
stages, using micro-level datasets of the Kangsabati River. The
book also includes practicable measures to minimize the
environmental consequences of instream mining in respect to optimum
sand mining. It discusses the threshold limits of each variable in
stream hydraulics, morphological and river ecological regime, and
also discusses the most affected variables. Consequently, all
outputs will be very useful for students, researchers,
academicians, decision makers and practitioners and will facilitate
applying these techniques to create models for other river basins.
