Colson 1978 <p>New techniques for predicting water-surface profiles, needed in the design of economical, structurally sound, and environmentally compatible stream crossings, are under investigation.&nbsp; The investigation has accelerated with the advent of digital computers capable of analyzing large quantities of data.&nbsp; Among the techniques is the development of two-dimensional (2-D) digital models.&nbsp; Field data are essential for development and evaluation of these techniques for predicting water-surface profiles.&nbsp; This atlas is the first of a series that will provide a wide range of field data.</p> application/pdf 10.3133/ha590 en U.S. Geological Survey Backwater at bridges and densely wooded flood plains, Tallahala Creek at Waldrup, Mississippi reports
