How much more rain will global warming bring?

Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A …

Concerns over Sabarmati Riverfront Development Project

construction on Gujarat's ambitious Sabarmati Riverfront Development Project in Ahmedabad, restarted in the second week of March, 2007. The project had been stalled since August 2006, when heavy floods inundated the city. Following this, the National Institute of Hydrology (nih) and Indian Institute of Technology (iit), Roorkee, were asked to …

Asian scientists on new plan to study monsoon patterns

a group of Asian scientists has framed a new plan to set up a comprehensive system to approach the study of changing monsoon patterns in Asia. A piecemeal approach towards the subject so far has led scientists to take this step. The plan, called mairs (Monsoon Asia Integrated Regional Studies), …

Hydrogeomorphological approach in water resource management in part of Chandraprabha Basin, Vindhyan Upland, Eastern UP

Hydrogeomorphological mapping is one of the best-suited approaches to explore the possibility of groundwater resources especially in those areas where availability of surface water in insufficient. The present paper is an attempt to study hydrogeomorphological features and their prospects for groundwater exploration in Chandraprabha basin, Chandauli District of Vindhayan Upland, …

Closing of the Krishna Basin: irrigation, streamflow depletion and macroscale hydrology

This paper summarizes research on the Krishna River Basin in southern India, including physical and agricultural geography, remote sensing, hydrology, water management, and environmental issues. Discharge from the Krishna into the ocean decreased rapidly from 1960-2003 due to irrigation expansion. Annual runoff to the ocean fell from a pre-irrigation average …

Nature`s Mystery

To identify the source and origin of groundwater, and to estimate the rate of recharge, there are a number of classical conventional methods but these are not very effective in solving problems. Isotope techniques, such as environmental isotope techniques and artificial radioactive tracers, have proved to be effective tools for …

Modeling hydrological response of the Upper Suriname river basin to climate change

The goal of this paper is to assess the impact of future climate change on the hydrological regime of the tropical Upper Suriname river basin (7,860 km2) located in Suriname. GCM based climate scenarios from the MAGICC/SCENGEN model and 14 hypothetical climate scenarios are used to examine potential changes in …

The day the land tipped over

Indonesia's major earthquake last year (2005) tilted Nias Island like a seesaw, disrupting villagers' lives and pointing to future dangers.

Detecting the long-term impacts from climate variability and increasing water consumption on runoff in the Krishna river basin

Variations in climate, land-use and water consumption can have profound effects on river runoff. There is an increasing demand to study these factors at the regional to river basin-scale since these effects will particularly affect water resources management at this level. This paper presents a method that can help to …

Role of Ganga and Brahmaputra in the scheme of interlinking Indian rivers

The present paper is an analysis of the scheme for the interlinking of rivers on a National Water Grid that would transfer water from one basin to another, from a water source having surplus water to areas with scarce water resources. The idea of interlinking two of the great river …

Hydrogeological environment and groundwater occurrences of the alluvial aquifers in parts of the Central Ganga Plain, Uttar Pradesh, India

A detailed hydrogeological investigation was carried out in parts of the Central Ganga Plain, India, with the objective of assessing the aquifer framework and its resource potential. The area was studied because of its dual hydrogeological situation, that is water logging and soil salinization in the canal command areas and …

Large dams not an answer to water shortage

It's that season again: when the prime minister, the Union and state ministers for agriculture and water resources, the Planning Commission, the World Bank and others busy themselves in finding a panacea for agriculture's ills. In fact, they do have a surefire solution: increase water storage capacities through large dams. …

Kerala`s backwaters carry modern day brunt

"God's own country is only an advertisement,' declares Cherian saar, a retired teacher in Champakulam, Alappuzha district, Kerala, as he gazes at the Pamba river flowing placidly by. All is not well with the trope of the famed Kerala wetlands, adopted by Kerala tourism as its flagship product. Kuttanad, covering …

Water resources and climate change: an Indian perspective

In recent times, several studies around the globe show that climatic change is likely to impact significantly upon freshwater resources availability. In India, demand for water has already increased manifold over the years due to urbanization, agriculture expansion, increasing population, rapid industrialization and economic development. At present, changes in cropping …

Water quality studies of Kolleru lake, Upputeru river and Enamaduru drain

Lakes are usually an integral part of a drainage basin. Lakes are either fresh water or salt water lakes. Kolleru lake is the largest freshwater lake in South India. Various physical and chemical inputs manifested through the hydrology of the catchment area will affect the quality and quantity of lake …

Non starters

Several critical programmes for groundwater recharge, micro-irrigation and rainfed agriculture failed to take off. The Central Ground Water Board (cgwb) recently estimated that 58 per cent of the total available groundwater is exploited as compared to 37 per cent in 1998. NSAR National scheme for artificial recharge : It's done …

Aral sea: experience and lessons learned

This report gives an overview of major environmental and socio-economic challenges that the Aral Sea region is facing, threats to the sustainable management of lake basin, major measures supported by the governments and international donor organizations aimed to address these critical environmental problems, and lessons learned from the environmental cooperation …

Conceptualization of project

Inception of Omkareshwar Project dates back to year 1955, when CWPC prepared a report on hydroelectric potential of entire Narmada river and the project has been mentioned as "Barwaha". It was also seconded in Khosla Committee report in 1965.

World commission on dams (WCD) recommendation on gaining public acceptance (GPA) for large dams on international rivers...

The construction of Tipaimukh dam by India on the international Barak river has raises a number of questions in relation to successful implementation of World Commission on Dams (WCD) recommendation on Gaining Public Acceptance (GPA) for large dams. The government of India had never officially informed the lower riparian state …

Identification of sea-water ingress using strontium and boron in Krishna Delta, India

The distribution trends of trace elements over North and South Krishna delta were examined in relation to fresh-, brackish- and saline-water zonations. Strontium and boron have shown significant variations in fresh-, brackish- and saline-water environment. Strontium has shown a variation from 23 to 1500 mg/l in freshwater, 1650 to 2760 …
