3D Visualization of Reservoir and its Applications in Fisheries: A GIS Perspective

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.
