This method is a mathematical model, in which all the components in the water balance equation are known, and the only component which is considered unknown is the rainfall recharge.

This paper begins with an analysis of the rationale for idol immersion in Hinduism. Some of the reasons given by the author include water being able to disintegrate idols, the idea of purity of water etc.

Since time immemorial water has been a common property and in many Indian communities there is deep reverence for flowing water. Using the flow of water for community benefit  is considered an act of great merit and  its misuse and contamination, a sin. In temples, tanks were constructed for rituals and also as a way to earn money for the temple.

The Indian Ocean extends over 30 per cent of the global ocean area and is rimmed by 36 littoral and 11 hinterland nations sustaining about 30 per cent of the world’s population. The landlocked character of the ocean along its northern boundary and the resultant seasonally reversing wind and sea surface circulation patterns are features unique to the Indian Ocean.

The project was a collaborative effort of the coordinators and scientists from the different modelling groups across the country. All the runs were made at the Centre for Development of Advanced Computing (CDAC) at Bangalore on the PARAM Padma supercomputing system.

 A model of the coupled ocean–atmosphere system, the climate forecast system (CFS), from the National Centre for Environmental Prediction (NCEP), USA, has been ported onto the PARAM Padma parallel computing system at the Centre for Development of Advanced Computing (CDAC), Bangalore and retrospective predictions for the summer monsoon (June–September) season of 2009 have been generated, using five initial conditions for the atmosphere and one initial condition for the ocean for May 2009.

The Western Ghats Ecology Expert Panel (WGEEP) of the Ministry of Environment and Forests, Government of India (GOI) had been asked to identify ESAs along the Western Ghats, and to suggest how to manage them. The concept of ESAs has been extensively discussed in the literature. Several ESAs have been set up in India over the last 22 years under the Environment Protection Act, 1986, and a GOI committee under the chairmanship of Pranob Sen has proposed certain criteria for identification of ESAs.

This report by Aligarh Muslim University and Central Ground Water Board (CGWB) deals with groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district. For evaluation of the groundwater resources and for minimizing the error of estimation, the system has been evaluated through aquifer modelling where water balance is established using partial differential equation of groundwater flow and is solved with boundary and initial boundary conditions.

Tanks are rainwater harvesting techniques which capture water during monsoons for later use. Mention of tanks in colonial texts is made and the authors infer from ancient texts like Tamil Purananuru on the importance of tanks and the locations for their construction, as well detailing their geographical spread.

This paper presents the ancient water and soil conservation eco-systems of Sri Lanka, based on ancient texts and their modern interpretations, and highlights the use of these water systems  in ancient Sri Lanka and their present condition.
