Abstract

Bathymetry is the foundation of the science of hydrography which measures the underwater physical
features of water-body. It is modern technique of active Sonar Technology which helps to track ocean navigation,
coastal areas, Reservoir, river and canal. The study focused on providing suitable locations for Dredging and
Training works in Matatila Reservoir. Information about reservoir profile is essential for maintaining water at Full
reservoir level [FSL] and reservoir management. Presently, Bathymetry technique is use of Multi-beam Echosounders [MBES] of variant frequencies for extracting features of underwater in 3-Dimension in GIS enabled
environment. Measurement of water depth up-to cm level of accuracy, under water surface contouring and mapping
reflects reservoir profiles more precisely. Through this, representative maps are prepared to show variations in depth
of water.
