Groundwater prospects evaluation based on hydrogeomorphological mapping using high resolution satellite images

Water is the most important natural resource which forms the core of the ecological system. The advent of remote sensing has opened up new vistas in groundwater prospect evaluation, exploration and management. The groundwater resources of the study area, Rishikesh region of Garhwal Himalayas, are under threat due to population …

Human-induced changes in the hydrology of the western United States

Observations have shown that the hydrological cycle of the western United States changed significantly over the last half of the 20th century. We present a regional, multivariable climate change detection and attribution study, using a high-resolution hydrologic model forced by global climate models, focusing on the changes that have already …

Yangtze at record low

The water level in China's longest river, the Yangtze, is at a record low. Water levels in some areas have fallen to the lowest in 142 years, officials said. On January 8, the Yangtze water level at Hankou hydrological station in Hubei province plunged to 13.98 metres

Stationarity is dead: Whither water management?

Systems for management of water throughout the developed world have been designed and operated under the assumption of stationarity. Stationarity-the idea that natural systems fluctuate within an unchanging envelope of variability-is a foundational concept that permeates training and practice in water-resource engineering.

Hydrogeological framework and water balance studies in parts of Krishni–Yamuna interstream area, Western Uttar Pradesh, India

A review of methods of hydrological estimation at ungauged sites in India

This paper reviews the estimation methods developed and used in India for low-flow, long-term mean flow and flood characteristics. The review is intended to provide a quick reference guide for such methods used for hydrological prediction in ungauged basins. As such it lists identified estimation formulae for various parts of …

Against the flow

Disregarding ecological and livelihood concerns, the Parbati hydroelectric project in Himachal Pradesh is moving forward. Experts warn that diverting water from the Parbati and its tributaries for power generation will leave the people in Kullu, where the project is coming up, with nothing to drink and irrigate their fields.

Forest legacies, climate change, altered disturbance regimes, invasive species and water

Climate is a major driver of forest species distributions and the growth rate and structure of forests. Thus, climate change can potentially have significant effects on mountain forest hydrology, particularly the amount of water available downstream. However, many other factors influence forest biomass and mountain hydrology, and climate change effects …

Study on hydrological behaviour of a natural spring

In the middle and greater Himalaya, natural springs are the main source of domestic water consumption, but their discharge does not remain constant with time. Erratic rainfall directly affects the recharging of the spring catchment. In this communication, the behaviour of a perennial spring with rainfall variation is analysed from …

Hydrogeological conditions around a limestone mine

A study has been conducted at the Naokari limestone mine located at Chandrapur district of Maharashtra state, to investigate the hydro geological condition between the mines and the surrounding areas. Water resources accounting by the demarcating different watersheds and quality of water has also been carried out to analyse major …

Impact of climate change on hydrological extremes: Floods and droughts

The two most important hydrological extremes are floods and droughts. These events pose serious hazards to human populations in many parts of the world. These water related disasters are caused because of large diversity in climate and topography of the country. Climate change in future is expected to have severe …
