        This is a collection of Lotus 123 templates, some of which were
        written with version 1 of 123, but have WK1 extensions because
        I have made minor revisions using version 2.00.  

        UNIFORM is the main menu for CIRC, RECT, TRAP and TRI and accesses
        those templates.  Alt A accesses a menu within each template.  You
        may also load a template directly.  These templates are used for 
        calculating uniform flow of water within circular, rectangular, 
        trapezoidal, or triangular channels, respectively.  They allow 
        flow, roughness, channel slope, and geometry of channel to be 
        input, and calculate a first trial for depth.  By entering a better
        guess in the proper cell, the trial calculations converge, to 
        whatever level of accuracy the user desires.  These templates were
        not written by myself, but are being put into the public domain 
        with this TXT file for the use of anyone who finds them useful.  
        They were furnished to me by Vern Peterman of Carson City, Nevada. 
        Thanks, Vern.

        CHANFLOW performs similar functions for triangular, trapezoidal,
        or rectangular channels, but in a different format.  By entering
        different top and bottom widths in one template, triangular or 
        rectangular or trapezoidal channels can be calculated by one 
        template.  Another section of the template allows bottom width and 
        fixed side slope to be entered.  A third section allows flow in 
        street gutters to be calculated for various depths of flow.  Flow 
        is not entered; depths are entered into these by trial and error
        until the desired flow is achieved.  A header has been preselected
        to print with whichever flow calc is selected for printing.

        COMP-C is a template for calculating composite runoff coefficient
        for the rational method of storm runoff.  It is based on Manual
        37 by ASCE.  The values in the referenced table in the Manual are
        averaged by the template.  It may be easily revised by the user
        to reflect his own judgement or local design criteria.

        CHANFLOW and COMP-C were written by myself, and are being placed
        into the public domain.  Rich Wadsworth, Civil Comp
