10、ydraulicdata set that could be used to compute sediment transport usingany prominently known sediment-transport equations.5.2 The criteria will address only the collection of data onnoncohesive sediment.A noncohesive sediment is one thatconsists of discrete particles and whose movement depends onthe
11、 particular properties of the particles themselves(1).Theseproperties can include particle size,shape,density,and positionon the streambed with respect to other particles.Generally,sand,gravel,cobbles,and boulders are considered to benoncohesive sediments.6.Procedure6.1 Parameters discussed here are
