The present study deals with the management of sediment characteristics and accumulation in the Vaigai reservoir situated in Theni District, Tamil Nadu, India. Data were obtained on the texture of sediments (Sand, Silt and Clay) in four different zones namely free flowing water, Top set water, fore set water and bottom water of the reservoirs during the different seasons (Premonsoon, Monsoon, Summer and Winter) of the year 2012. Distribution of sediments and grain size analyses were also investigated in the samplings collected once in a month throughout one year, January 2012 to December 2012. Based on sediment samplings collected from the four zones, sediment characteristics and relative abundance of grains in percentage were understood. Such investigators help in the management of Vaigai reservoir to gather with the useful information needed for agriculture and drinking water for human life.
