Open Channel Flow Pro is a hydraulic calculator for open channels. It solves uniform and critical flow, draws the water surface profile, and reports energy, momentum and the hydraulic jump, for six channel shapes. It is made for civil and irrigation engineers, and for students of hydraulics. SIX CHANNEL SHAPES . Rectangular . Trapezoidal . Triangular . Circular . Parabolic . Natural: a cross-section you enter point by point, with separate overbank roughness WHAT IT CALCULATES . Uniform flow by Manning's equation: solve for discharge, depth, bed slope and more . Area, wetted perimeter, hydraulic radius, top width, velocity, Froude number and hydraulic depth . Critical depth, critical velocity and critical slope . Specific energy, momentum and the sequent depth of a hydraulic jump . Water surface profiles: gradually varied flow from a control depth by the direct step method . Rating curves of discharge against depth . Design aids: most efficient section, freeboard and shear stress MADE FOR REAL WORK . Metric or English units on every form; values you have typed convert . A list of Manning's n values to choose from . Charts on every results screen . PDF reports you can share or print . Worksheets that keep your calculations . Messages under each field when an input is not valid . Built-in documentation of the equations and terms . Works offline, on iPhone and iPad Disclaimer: results should be checked before they are used in design. Professional use is at the discretion of the user.
