The Mactaquac Dam and Generating Station, a 672 MW run-of-the-river hydroelectric facility located on the Saint John River, Canada, will have to be decommissioned or reconstructed by 2030. In order to simulate the impact of reservoir emptying (drawdown) and climate change on the thermal regime of the lower reaches of the river, the CEQUEAU hydrological and water temperature model was used.

Ground Water Year Book is prepared annually by CGWB depicting changes in ground water regime of the country through different seasons. It is an effort to obtain information on ground water levels through representative monitoring wells. The important attributes of ground water regime monitoring are ground water level.

The Tana River is one of Kenya’s most important rivers. It is the principal water source for Nairobi, the capital city, providing water for hydroelectric power generation and irrigation. Several of the flagship projects laid out in Vision 2030 – the blueprint that guides Kenya’s national development – are located in the basin.

A critical question for agricultural production and food security is how water demand for staple crops will respond to climate and carbon dioxide (CO2) changes, especially in light of the expected increases in extreme heat exposure. To quantify the trade-offs between the effects of climate and CO2 on water demand, we use a ‘sink-strength’ model of demand which relies on the vapour-pressure deficit (VPD), incident radiation and the efficiencies of canopy-radiation use and canopy transpiration; the latter two are both dependent on CO2.

Global warming is expected to intensify the Earth’s hydrological cycle and increase flood and drought risks.

Judgement of the National Green Tribunal (Eastern Zone Bench, Kolkata) in the matter of Tenzing Lepcha & Others Vs Ministry of Environment and Forests & Others dated 15/11/2017 regarding Teesta-IV Hydro-Electric Project on the Teesta river near Chandey Village on left bank and near the Gyathang Village on the right bank in North district of Sikkim. The project envisages construction of a 65m high concrete gravity dam across Teesta river in downstream of confluence of Runchu with Teesta for a generation of 520 MW hydropower.

Judgement of the Supreme Court of India in the matter of National Institute of Medical Science University Rajasthan & Others Vs State of Rajasthan & Others dated 09/11/2017 regarding water shortage in Jaipur city and the drying up of Ramgarh Lake. The case deals with the massive encroachments in the catchment areas of Ramgarh Dam especially by the National Institute of Medical Sciences University or NIMS.

Order of the National Green Tribunal in the matter of Pratiba Naitthani Vs. Union of India & Others dated 07/11/2017 regarding Gauri Kund spring near Kedarnath in the Himalayan Range in the State of Uttarakhand.

NGT directs the State of Uttarakhand and CGWA to make every effort to restore the hot spring which had been destroyed in 2013 during a natural calamity.

Developing countries around the world are expanding hydropower to meet growing energy demand. In the Brazilian Amazon, >200 dams are planned over the next 30 years, and questions about the impacts of current and future hydropower in this globally important watershed remain unanswered. In this context, we applied a hydrologic indicator method to quantify how existing Amazon dams have altered the natural flow regime and to identify predictors of alteration.
