Abstract : This report contains a detailed description, and instructions for use, of an IBM-650 program developed to calculate multiple backwater profiles. The prime objective of this development is to provide an accurate, easy-to-use, general-purpose backwater computation program which would be economical in regard to data preparation effort and computer time. The program will compute from one to twenty-four water-surface profiles for large or small streams. The stream may be defined by an unlimited number of cross sections, each of which may be subdivided into channel and overbank (partial sections). The partial sections may have independent values of Manning's n, reach length (L), and velocity distribution coefficient (a). The discharge may be changes at any cross section without interrupting the computation. Provision has also been made for computation of backwater curves due to friction (neglecting velocity correction).
