The Farakka Barrage Project on river Ganga, commissioned in the year 1975, mainly for diversion of 1135 cumec flow of water from river Ganga to river Hoogly through Bhagirathi, for the preservation of Kolkata Port. River Ganga due to its meandering nature is causing bank erosion problems not only in the vicinity of barrage but also in the reaches for upstream and downstream of the barrage.

One surviving stronghold of endangered Northern swamp deer is Jhadi taal (lake) in Kishanpur Wildlife Sanctuary on the floodplains of Sharda River. Changes in channel characteristics and land use/cover in a

Stream restoration needs to consider the hyporheic zone just as much as the surface and benthic regions.

A three-dimensional mathematical model to simulate regional groundwater flow was used in the coastal area of Kanyakumari district in South Tamil Nadu. The study area is characterized by heavy rainfall, less extraction of groundwater for agricultural, industrial and drinking water supplies.

Hydrogeological and geomorphological parameters have been quantitatively correlated with groundwater availability. Weathered rock thickness has the highest control on availability of groundwater followed by lineament density whereas drainage density is seen to have minimum influence. A poor correlation is noticed between borewell depth and yield.

Although no region of the world will be entirely spared, the negative impacts are likely to fall most heavily on poor nations in the tropical region. While data on the global impacts of climate change is available, those at regional levels are scanty and scattered. This prompted this study that took a general overview of climate change impacts in Nigeria.
