INTRODUCTION OF SEMINAR
 Remote sensing (RS), also called earth observation, refers to obtaining
information about objects or areas at the Earth’s surface without being in direct
contact with the object or area .
 Remote sensing techniques allow taking images of the earth surface in various
wavelength region of the electromagnetic spectrum (EMS) s.
 The Remote Sensing is basically a multi-disciplinary science which includes a
combination of various disciplines such as optics, spectroscopy, photography,
computer, electronics and telecommunication, satellite launching etc.

5. D. Nagesh Kumar et.al.,(2013) Remote sensing techniques have been
widely used to delineate the surface water bodies, estimate
meteorological variables like temperature and precipitation, estimate
hydrological state variables like soil moisture and land surface
characteristics, and to estimate fluxes such as evapotranspiration
This paper gives a brief overview of the potential applications of
remote sensing in water resources.
LITERATURE REVIEW

6. 6
 Proper Management of surface and water resource is an important step
against water scarcity.
 Remote sensing systems deployed on Satellites provide repetitive and
consistent view of the earth.
 Planning for the resource utilization and decision making heavily
depends on a faithful inventory of earth's resources.
 To Set up a water resources management model over GBM basins.

CASE STUDY
 The first successful airborne imaging radar was not used for
civilian purposes but proved valuable for nighttime bombing.
 As such the system was called by the military ‘plan position
indicator’ and was developed in Great Britain in1941.
 After the wars in the 1950s remote sensing systems continued
to evolve from the systems developed for the war effort. Color
infrared (CIR) photography was found to be of great use for the
plant sciences.

8. ADVANTAGES
Remote sensing techniques can be used to monitor water quality parameters
(turbidity, chlorophyll, and temperature) Integration of remotely sensed data, GPS,
and GIS technologies provides a valuable tool for monitoring and assessing water.
Remote sensing allows repetitive coverage which comes in handy when collecting
data on dynamic themes such as water, agricultural fields and so on.
DISADVANTAGES
Some of the satellite imagery are costly.
 Human induced errors are possible in remote sensing during the process of
interpretation, analysis etc.
ADVANTAGES AND DISADVANTAGES

9. An overview of the remote sensing applications in different fields of
water resources shows the potential of the remote sensing data in
water resources management.
The possibility of Earth observation can potentially optimize the
ground measurements and in such sense Earth observation is simply
awesome and can play a crucial role in water resource management
but there are several changelings that we need to attain to successfully
couple water specialist with Earth observation.
