🌟Lacey's Theory:-
Applicable to Irrigation channels and rivers.
Applicable If sediment Concentration is Less than 500 PPM
Bed form is Dune Type.
It is a Regime theory.
Indian Standard recommends Laceys theory.
Use Mannings formula as a Resistance equation.
3 basic equations are proposed
🌟Kennedy's Theory:-
Applicable to Irrigation channels only.
Disadvantageous theory
No equation given for slope.
No importance assigned to the B/D ratio.
Uses kutters formula as A resistance equation.
Garrets Diagram are based upon kennedys theory.
Woods tables may be used.
✨Tractive force approach:-
Based upon Boundary shear concept.
Critical Tractive stress can be calculated by using shields expression or whites expression.
