<p> Stream Channel Morphology & Hydrology</p><p>I. Channel Morphology A. Variables 1. W = width 2. D = depth 3. S = slope 4. A = cross sectional area 5. R = hydraulic radius 6. P = wetted perimeter B. Flow Q = AV C. Uniform flow Q = A1V1 = A2V2 D. Laminar vs. turbulent flow 1. viscous vs. gravitational forces 2. Reynolds number NR = ρ [VR/µ] E. Turbulent flow 1. Streaming flow vs. shooting flow 2. Froude number F = [V/ √gD] F. Effects of the channel bottom 1. Chezy formula V = [C √RS] where C is a constant 2. Manning’s number V = 1.49/n * R2/3 * S1/2 Where n is Manning’s number – a measure of bottom roughness </p><p>II. Energy and Work A. Energy 1. Potential energy Ep = Wz 2. Kinetic energy Ek = [MV2/ 2]</p><p>III. Transport and load A. Dissolved load B. Suspended load C. Bed load E. Work of the stream 1. competency 2. capacity D. dynamics of transport</p><p>III. Valley Morphology A. The long profile B. Drainage basin metrics C. Stream order D. Other drainage features 1. terraces 2. meanders E. Stream adjustment F. The graded profile</p>
