The Satellite Remote Sensing (SRS) method for assessment of reservoir sedimentation uses the fact that the water spread area of reservoir at reservoir boundaries keeps on increasing due to sedimentation. Remote Sensing technique gives directly the water spread area of the reservoir at a particular elevation on the date of pass of the satellite. This helps to estimate sedimentation over a period of time. This research project describes assessment of sedimentation carried out for the Kiira Reservoir using Remote Sensing satellite imageries. The area capacity curve of year the 2001, is used as a base for sedimentation assessment for the year 2010. The results of Remote Sensing survey for the period 2001 to 2010 are compared with the deposition pattern of Kiira Reservoir with the standard types of deposition pattern as per Area Reduction Method suggested by Borland and Miller. As per recent Remote Sensing survey of 2006 and 2010, it was observed that the original water spread area had increased to 4.82km2and 4.96km2respectively i.e. by approximately 3.549% in 9 years. Thus, there is a gradual reduction in the capacity of Kiira reservoir. The validation process which involved collecting field data and incorporated with the remote sensing data gave an evidence of sedimentation in Kiira dam at the sample point locations as indicated the preceding chapters.
