Abstract
Reservoirs are water bodies created using a dam for
storage of water. Natural process like erosion in the
catchment area and the consequent deposition in
various parts of reservoir gradually reduce the
capacity of the reservoir. This silt deposition from
the upland and surrounding areas poses a threat to
the aquatic environment in general and fisheries in
particular. Information about the quantity of the silt
and the consequent reduction in the capacity of the
reservoir is necessary for planning and operational
purposes and the same can be estimated through
scientific capacity surveys. It is also essential to
identify the geomorphological characteristics of the
bathymetric area of the reservoir for management of
fisheries. This article reviews the research works
carried out for development of three dimensional
visualization of reservoirs in GIS platform for
sustainable fishery management.
