Reservoir sedimentation studies in Andhra Pradesh Department of Irrigation and Command Area Development, Government of Andhra Pradesh supported by Sedimentation Division, Andhra Pradesh Engineering Research Laboratory
 
Objectives
 
To use Integrated Boat Mounted Bathymetric System to undertake surveys of five major reservoirs in Andhra Pradesh to quantify losses of storage due to sedimentation.
 
Results and Recommendations
 
To date only one reservoir has been surveyed: Priyadarshini Jurala reservoir on the Krishna River.
Since it first started impounding in 1996, 19.1% of its capacity has been lost due to sedimentation; 12.1% of the dead storage capacity and 7% of the live storage capacity.
This is equivalent to 0.49 ha m/100km2/year
