On the basis of a climate modelling study, Lal et al. predicted that during the winter months there will be 5–25% less rainfall and in the summer season the monsoon rainfall will be not only 10–15% more than the normal, but also quite variable and specially irregular in Central India.

An industry approach to greener hydropower is far from perfect, but it does offer a way forwards. (Editorial)

Those who enjoy the wetlands and seafood of New England's coastline may be surprised by who they have to thank: the loggers of the 18th and 19th centuries. In clearing vast tracts of land, those prolific loggers released so much sand and dirt that open-water bays turned into swamps.

Recolonization of benthos following dredging operations was studied in Mormugao Port Trust Harbour, Goa. Six stations were fixed for sampling within the radius of the dredging site. Three samples each were collected during dredging and after dredging.

A treatability study was conducted to determine the most effective bioremediation strategies for the decontamination of sediments dredged from industrially polluted Gandigudem Lake. Microcosm  experiments  were  performed  with  the  addition  of  a  microbial  consortium  and

Soil erosion is a natural process accelerated by human activities. Each year, erosion of surface soil from river basins amounts to 60 billion tons, resulting in 24 billion tons of sediment flux to the oceans in the world and almost 25 billion tons of soil lost from agricultural land.

This paper depicts a research work comprising an attempt to estimate the rate of sedimentation from the basin surface of the Malampuzha, typical multi purpose storage reservoir on the western slopes of the Western Ghats in the Kerala state.
