TurtleFlow provides a quick and easy way to calculate open channel flow in four types of culverts; circular, rectangular, triangular, and trapezoidal. TurtleFlow uses Mannings Equation to calculate flow and velocity in both imperial and metric units. Quick input and easy roughness coefficient selection makes TurtleFlow a great program for Civil Engineers.
TurtleFlow is available as this stand alone program. It is also available as a module included in TurtleCalc. TurtleCalc also includes additional useful modules for civil engineers and water industry professionals.
