This paper discusses river linking, as a part of an ancient tradition, and suggests how NGOs can play a role in this attempt. The example of the Koyna dam is taken, and the effective handling of the technical and human angle of the dams construction is detailed through in-depth study and detailed field visits.

This paper attempts to discuss farm water conservation techniques and multiple  cropping patterns with the idea of minimising water use. The authors provide a glimpse of agricultural facts that include total geographical area, net sown area etc. They provide population trends in the country to point out to the water and food stress.

This paper discusses the role of paleochannels, which are remnants of stream channels cut in older rocks/sediments and filled by younger overlying sediments, representing the distribution of valley systems, in meeting current and future water requirements.

This paper describes a lake in one of the forests through which the Hindu god Ram and his brother Laxman passed, during their search for Sita. A virtual picture of the forest and the lake (Pampa Sarovara) in it using the Valmiki Ramayana which is a religious biopic of Ram's life on earth is created. This lake is situated near the town of Hampi in Karnataka today, and the forest is a rich source of water to this day.

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 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.

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.
