The report presents an inventory of water bodies in the State of Jammu & Kashmir in the Western Himalayan region prepared using satellite data of IRS-1A (standard FCC, scale 1:250000) for 1988/ 99 and digital data of IRS-1C for 1998. Also, presented is a database developed with the help of Survey of India (SoI) topographic maps, which includes name and type of the water body, nearest place, district, river basin, geographical coordinates and elevation.

The study carries out sediment yield estimation for the Shakkar catchment of the Narmada river in Madhya Pradesh and successfully implements a methodology for prioritization using Geographical Information Systems (GIS) and image processing on ERDAS and ILWIS software.

The report presents the preliminary results of a hydrological study in Danda watershed, a small hilly watershed located in Tehri-Garhwal, representative of the mountainous sub-humid agro-ecological region in the western Himalayas.

The report develops rainfall-runoff modeling for simulating and forecasting the flow from a catchment, and in determining the inflow series for the ungauged catchments on the basis of records of gauged catchments.

Because of the scarcity of data, mostly lumped models have been used to model the rainfall-runoff process in a catchment. However distributed models are more accurate and need to be adopted for modeling the complex processes at the scale of basins.

The study presents automated mapping of snow cover using a new spectral channel of Indian Remote Sensing (IRS-IC) data for the Spiti sub-basin of the Satluj river basin. Snow is an important phase of the hydrological cycle and the estimation of snowmelt runoff in the Himalayan rivers, either seasonal or daily, is of immense use in proper management and use of water resources in the basins.

The study attempts to quantify geomorphological characteristics, generate various thematic databases in Geographic Information Systems (GIS) format and derive landuse information using remote sensing digital data for the Danda watershed in the Tehri-Garhwal district of Uttarakhand. Based on these it develops a land capability classification and generates alternate land use plan.

An integrated approach is followed wherein remote sensing and Geographical Information systems (GIS) techniques have been utilized for evaluation of the catchment characteristics such as geomorphology, landuse, soil and slope. The linking of the geomorphological parameters with the hydrological characteristics of the basin provides a simple way to understand the hydrologic behavior of the basin.

This set of maps of Indian towns and cities, dated between 1893 and 1924, give an idea of historical water bodies in each town/city, and can be compared with present day maps, to discover water bodies, that may have been lost to urban encroachments or other human interventions.

Ponds are important sources of fresh water in the world as they store surface runoff produced by the storms. In this research paper, demarcation of the portion of land contributing runoff to ponds in village Nandgaon (Uttar Pradesh) has been done using topographical information of the surrounding area of the ponds, in a GIS interface.
