Abstract :

In the present research work, an attempt has been made to study the plan view of Tulsi and Bhogawati River. The study area forms a part of Tulsi channel from its dam to its confluence near Bid and a channel of Bhogawati from Radhanagari Dam to Prayag Chikhali of Kolhapur District. Channel in plan means, the various channel patterns of river i.e. straight, sinuous, meandering and aided. The study of river plan–form is significantly essential for river restoration and river conservation. Apart from hydrological events, unplanned agricultural activities and deforestation in the basin is extremely responsible in channel erosion and shifts in channel locations that is one of the causes for the variation in sinuosity index of the channel. River is generally controlled by geological characteristics of basin and its plan form, which equally influence on channel slope and shows the erosional or depositional signs of the river. Geomorphic characteristics and within channel variations are also influenced by the variability in river basin and its hydrology. The study of channel in section and channel in plan also predicts the future channel deposition and erosion. Therefore an attempt has been made to study the channel patterns and channel variability of Tulsi and Bhogawati River
