Evaluation of the Stream Simulation Culvert Design …

(2 days ago) The stream simulation method of culvert design has two basic parameters, culvert bed width and slope. The complete design of a culvert is a complex affair involving bed material specification and adjustment in channel profile, among other issues, but slope and width are most fundamental. These parameters are a function of a representative reach
