- 4. 4 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. 4
- 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 5
- 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. OBJECTIVES 6
- 7. 7 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 10
- 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.
