This open channel calculator calculates normal flow parameters for either uniform flow or gradually varied flow. The program options, input required and output generated is listed below.
Units English - feet, cfs, ft^2, ft/sec Metric - meters, cms, m^2, m/sec
Uniform Flow Input Required -
Side Slope H:V Base Width Channel Bottom Slope Manning's n Depth Flowrate
Gradually Varied Flow Input Required -
Side Slope H:V Base Width Channel Bottom Slope Manning's n Depth (downstream or upstream depending on profile type) Flowrate Alpha Select Profile Type Backwater (downstream to upstream) Frontwater (upstream to downstream) Select Mathematical Profile Method Direct Step - Chosen depth increments, solves for distance along channel at depth Number of Steps Standard Step - Chosen length increments, solves for depth at given locations. Number of Steps Total Length of Segment
Normal Flow Parameters (Output) - Critical Depth = Discharge = At Normal Depth: Flow Area = Wetted Perimeter = Hydraulic Radius = Average Velocity =
