Abstract : The Van Buren reach of the Arkansas River is in Lock and Dam No. 13 pool near Van Buren, Ark., about river mile 353. The reach is characterized by three relatively flat bends and is crossed by three existing or proposed bridges. The location of the navigation spans of the two existing bridges could cause considerable difficulties in navigating the reach and in maintaining a channel of adequate dimensions based on the alignment of the navigation spans. A hydraulic model reproducing about 4 miles of the Arkansas River including the three bridges was constructed to an undistorted scale of 1:120. It was used to determine (a) the best location for a navigable channel; (b) the modifications required to the two existing bridges; (c) adequacy of the proposed structures in the development of a satisfactory channel; and (d) modifications needed to improve navigation conditions and channel depths through the reach.
