Comments:
Large timber crib dam for a historic mill site influences bedform and sediment transport for entire reach. Channel is overwidened due to major retention of cobbles and gravel above the dam. Bankfull height was very low due to widened channel, leading to a low entrenchment ratio and a designation of F-type geometry. Road embankment on LB has led to a human caused changed in valley type from narrow to semi-confined. Combination of road encroachment and channel alterations due to dam sediment retention affect confinement/entrenchment leading to stream type departure.
