Watershed management Watershed management is a term used to describe the process of implementing land use practices and water management practices to protect and improve the quality of the water and other natural resources within a watershed by managing the use of those land and water resources in a comprehensive manner 6 7. What is Prioritization? Participatory Action Plan Preparation 13 Points to be considered before taking up impact studies 1. Satellite images should be obtained only after considerable time after implementation.
Conditions should be similar for pre and post treatments. Ex- Rainfall- quantum, distribution, etc. Availability of satellite data for required dates. Resolution of satellite data - should be same for pre and post treatment.

Data base on natural resources does not exist. Further, information on soil resources, land forms, geology and ground water prospects are absent in such maps. Scientific methodology for assessment of the impact of the action plans are virtually non-existent. Information Technologies in Watershed Management 1. Remote Sensing RS 3. The position is determined from the distance measurements to satellites. The four satellites are used to determine the position of the receiver on the earth. GPS consists of satellite, control station and monitor station and receiver.
Geographic Information Systems GIS GIS has the ability to manipulate spatial data and corresponding attribute information to integrate different types of data analysis at high speed, which is unmatched with manual methods The database available in GIS environment facilitates assimilation of different thematic datasets to understand interrelationships GIS plays an important role in information management, analysis and providing solutions to the planning of natural resources It is also useful in delineating hydro-morphological units in the area 21 GIS are a special class information systems that keep track not only of events, activities, and things, but also of where these events, activities, and things happen or exists.

1. Introduction and Background Information
Ramakrishnan Y. Srivastava Vinu Chandran A. Integrated watershed management requires a host of inter-related information to be generated and studied in relation to each other. Remote sensing technique provides valuable and up-to-date spatial information on natural resources and physical terrain parameters.
Geographical Information System GIS with its capability of integration and analysis of spatial, aspatial, multi-layered information obtained in a wide variety of formats both from remote sensing and other conventional sources has proved to be an effective tool in planning for watershed development.
