ABSTRACT :

Submarine fan and its channel system perhaps the least known large morphological feature on Earth. Many active and passive submarine channel systems have been discovered in the ocean margins. Some of these systems are extend as long as several thousand km long. Indus fan is reportedly the second largest submarine fan, having a well-developed active canyon and deepsea channel system. The major morphological feature of mid Indus fan have been mapped and studies with recently acquired high resolution multibeam bathymetry data. The channels observed in the mid Indus fan are shallow with average depth of about 60 m and varying spreads from 189.8 m to 1980.5 m. These channels are very similar to the land based fluvial channels and their morphometry, sinuosity have been studied. The channels are highly sinuous in nature and channel course are more than twice the straight course. Channel sinuosity varies from 2.12 to 3.21, correlated with global sinuosity variation of submarine channel system. Key Word: submarine channel. Submarine Fan, Sinuosity, Indus fan
