Experience of Application of Hydro/acustic Profilograph for Estimation of Bottom
Sediments of Large Reservoirs (the Argazin Reservoir as a Study Case)

The work considers application of the method of sub-bottom profiling of
bottom sediments of a large reservoir with the use of modern instruments. Such studies are effective in assessing the volume of bottom sediments and the nature of their occurrence.
The use of acoustic profilographers in combination with control sampling of bottom
sediments without disruption of their vertical structure (column) enables to obtain at
minimum costs the necessary set of initial information for planning of further measures.
