WSPGW: Water Surface Pressure Gradient for Windows

Water Surface Pressure Gradient for Windows (WSPGW) Version 12.96 & up is approved by FEMA! See FEMA's website for a list of Approved Hydraulic Numerical Models:

WSPGW is designed to assist the engineer in designing or evaluating storm drains or channels. The program includes the ability to automatically create a precision plan and profile drawing file of the channel, hydraulic data, and results. The program computes and plots uniform and non-uniform steady flow water surface profiles and pressure gradients in open channels or closed conduits with regular or irregular cross-sections. The flow may alternate between supercritical, sub-critical, and pressure-flow in any sequence. The program will analyze natural river channels with up to 35 cross-section data points, although the principal use of the program is intended for determining profiles in improved flood control systems.
