This research report by the National Institute of Hydrology deals with optimum water management in a command area. The dynamics of water within the unsaturated zone of soil is a complex phenomenon dependent on properties of the atmosphere, soil and vegetation. For agriculture water management, it is necessary to have models that accurately predict the behavior of soil moisture.

In this study, a model is developed to stimulate the dynamics of soil moisture within the root zone in an agriculture command. Focus is given to incorporate the spatial variation in crop type, soil type and rainfall in the command area and the dynamics of soil-water-plant interaction is stimulated.

This report by National Institute of Hydrology provides a compilation of the hydrological information of seventeen different river basins of South Bihar (now Jharkhand). Hydrological modeling of a basin requires detailed hydrological information about the basin. Further, the hydrological information of a region or a basin is of immense use to water resources planners and managers. However, the hydrological information collected by different organizations are often scattered and are not in representable form.

The map indicates that across the main 19 river basins of the country, water resource projects with a total live storage of 174 BCM (Billion Cubic Metres) have been completed, 75 BCM are ongoing, and 132 BCM are being planned.

The total flood prone region in the country is 40 million Ha, of which about 32 million Ha, can be given protection. Until 1954, only 3 million Ha were protected, while as of 2004, about 15.8 million Ha has been protected. The average annual damage due to floods is estimated at Rs.

Land is used for agriculture, for growing forests, for grazing animals, for mining, for installing industries and for construction of houses, roads, railways, etc. For sustainable development and prosperity of any country, the proper and wise use of the land is required.

This papers models the saline water intrusion in the Bardez taluk of Goa.

The study is replete with hydrogeological maps and data. These include topographic contours, soil, landuse, rainfall, geology, location of observation wells etc.

This report on the Effect of Climate Change on Water Resources, prepared by the Central Water Commission and the National Institute of Hydrology, under the guidance of the Ministry of Water Resources in 2008, is one of the first official reports made available by the Government of India, of a reliable quantitative assessment based on field data, of the likely effect of climate change on the availability of water resources, i.e. on the glaciers and snow melt, on rainfall and their effect on run off into the river system and their contribution to ground water.

This study by the National Institute of Hydrology deals with the geomorphologic & land use planning for Danda watershed in Tehri Garhwal district of Uttar Pradesh.

The Preliminary Consolidated Report on the Effect of Climate Change on Water Resources, prepared by the Central Water Commission and the National Institute of Hydrology, under the guidance of the Ministry of Water Resources in 2008, is one of the first official reports made available by the Government of India, of a reliable quantitative assessment based on field data, of the likely effect of climate change on the availability of water resources, i.e. on the glaciers and snow melt, on rainfall and their effect on run off into the river system and their contribution to ground water. In the Report, an attempt has been made to give a brief account of the available studies on possible impacts of climate change on India's water resources, change in India's water needs, climate of India, river basins of the country, present water resources and future demand and supply, impacts of projected climate change and variability, and associated hydrological events and likely vulnerability of regional water resources to climate change. Identification of key risks, research needs and prioritisation of mitigation strategies has also been discussed.
