Summary of WSPRO88

       wspro88 - A computer model for Water-Surface PROfile computations

       WSPRO computes water-surface profiles for subcritical, critical, or
       supercritical flow as long as the flow can be reasonably classified
       as one-dimensional, gradually-varied, steady flow.  WSPRO can be
       used to analyze:  (1) open-channel flow; (2) flow through bridges;
       (3) flow through culverts; (4) embankment overflow; and (5)
       multiple-opening (two or more separate bridge and (or) culvert
       structures) stream crossings.  WSPRO is designated HY-7 in the
       Federal Highway Administration (FHWA) hydraulics computer program
       series.  A primary objective in developing WSPRO was to provide
       bridge designers with a highly flexible tool for analyses of
       alternative bridge openings and (or) embankment configurations.
       However, WSPRO is equally flexible and suitable for analyses of
       existing stream crossings.  Much of the model's flexibility can be
       attributed to the data input scheme which, to a great extent, is
       designed for unformatted, order-independent data.  Additional
       flexibility is provided by propagation of constant data and limited
       capabilities for synthesizing cross sections.  Also, many desirable
       features from other models were incorporated into WSPRO.  The type
       and quantity of output is to a large extent user-specifiable.  Thus
       WSPRO is a very easy-to-use model, which is generally applicable to
       water-surface profile analyses for highway design as well as for
       problems related to flood plain mapping, flood insurance studies,
       and estimating stage-discharge relationships.

       Open-channel computations use standard step-backwater computational

       Single-opening bridge backwater free-surface flow uses an energy-
       balancing technique that uses a coefficient of discharge (which is a
       function of flow characteristics and bridge geometry) and estimates
       an effective flow length (which takes into account the conveyance
       characteristics of both the bridge opening and the valley upstream
       from the bridge).

       Single-opening bridge backwater pressure flow uses orifice-type flow
       equations as developed by the FHWA.

       Flow through culverts use FHWA computational techniques of
       regression equation for inlet control and energy balance for outlet

       Embankment (road) overflow uses broad-crested weir equation.

       V060188 - FHWA/USGS official version for use on PC's and UNIX
          workstations.  WSPRO was developed by the U.S. Geological Survey
          for the Federal Highway Administration, Offices of Research,
          Development, and Technology.

       Version 6/83 - E431 Step-backwater and floodway analysis program.

       Successful application of the model, data collection, and proper
       interpretation of model output requires a reasonable level of
       hydraulics expertise.  Input data consists of coordinate data
       defining the cross-sectional shape referenced to known vertical and
       horizontal datums, roughness coefficients, flow lengths,
       discharge(s), starting water-surface elevation(s), pier data, bridge
       geometry data, subarea breakpoints, culvert geometry, and program-
       control parameters.  WSPRO has many built-in default values and
       allows constant data propagation to minimize data coding
       requirements, while allowing defaults to be overridden easily.  The
       initial boundary condition is either the water-surface elevation or
       energy gradient at either end of the study reach for the specified
       discharge.  If it is not specified, WSPRO defaults to the water-
       surface elevation for critical flow.

       WSPRO generates rather detailed output describing the processing of
       the input data and the results of all profile computations.  Tables
       of cross-sectional properties and (or) velocity and conveyance
       distribution are available optionally, except for road-grades and
       culverts.  Cross-section plots can be produced in line-printer
       format.  Tables of selected parameters can be defined by the user to
       produce a specific output format.  WSPRO has 55 computed parameters
       that may be used to build a table.  User-defined tables cannot be
       generated for multiple-opening analyses.

       WSPRO is written in Fortran 77 with the following extensions:  use
       of the $ format descriptor and reference to compiler-dependent
       system date and time routines.  Generally, the program is easily
       installed on most computer systems.  The code has been used on UNIX-
       based computers and DOS-based 386 or greater computers having a math
       coprocessor and 1 mb of memory.
