Research Papers

To highlight the value placed on water and to describe water supply systems, the authors quote from the Chandogyo-Upanishad, Yajurveda and other ancient Indian texts.

This paper focuses on water management techniques used in two tanks constructed by the kings of the Vijaynagar Empire.

The first example taken, is that of the Anantraj Sagar built by the son of the minister of Harihar. The lake is still in use and there are inscriptions on stone near it which provide a thumb rule to constructing lakes. Construction of this lake began in 1369 and was completed in 2 years. The paper states that the length of the dam was 5000 dand, width was 8 dand and the height was 7 dand (One dand is about one metre).

This paper discusses the water management systems found in temples in coastal Konkan, based on a study of 5 temples in the district of Ratnagiri. The study area is a rocky and rugged country, with elevated plateau and intersecting creeks.

The Phad system of irrigation which has been going on for centuries, is found in the northwestern parts of Maharashtra in the three river basins of Panjhra, Mosam, Kan and Aram. Weirs were constructed on these rivers to divert water for agriculture use. These weirs are locally called Bandhara. Each independent Phad system comprises of a diversion weir, a canal on the bank and distributor channels for irrigation.

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.
