WebWhen a channel is flowing through a material that can be scoured easily then such soil is known as incoherent alluvium. 2. Initial Regime: A channel is in the initial regime when the bed slope gets affected due to silting and scouring. The regime theory is not valid for the initial regime. 3. Final Regime: WebWikipedia
