I. INTRODUCTION
Over the past decades the satellite based techniques and the use of remotely sensed data have
achieved a major progress and is now becoming a promising approach in wider range of disciplines.
Remote sensing is the science and art of obtaining information about an object, area or phenomenon
on the earth surface without being in contact with it (Agyepong, 1988, Agyepong and Kufogbe,
1997). The technique, according to Benneh (1997), overcomes the two major problems inherent in
ground survey, that is, area coverage and time. GIS is a too! For collecting, storing, retrieving at
will, transforming, and displaying spatial data from the real world for a particular set of purposes
(Bourrough, 1986). As a database system, it facilitates spatial data indexing and enables the
performance of sets of operations to answer queries about spatial entities in the database (Smith et
a/., 1987). The GIS technique has, thus, become very useful aiding decision making in planning and
development, including irrigation and agriculture.
The most populous state, Uttar Pradesh, is also endowed with the largest water resources in the
country. A large network of perennial rivers contributes to its vast water resources potential and
