• Abstract:
  The determination of the shape and characteristics of a backwater profile in a closed conduit is generally a lengthy and tedious procedure without the use of a computer. Utilizing the charts and tables of this publication and a few simple calculations, it is possible to completely define an M2 profile in a circular structural plate corrugated metal pipe with 6 x 2 inch corrugations. The depth of flow, velocity head, and specific head may be determined at various points along the backwater curve, and the total length of the backwater curve may be defined. Use of the publication will also provide the user with a better understanding of the effects of flow parameter variations on the shape and extent of the backwater profile.
