Open channel flow is the movement of water with a free surface exposed to atmospheric pressure, such as in rivers, streams, roadside ditches, storm drains flowing partially full, and irrigation canals. Flow Calc™ is a robust and advanced software application designed to perform open channel flow calculations using the Manning Equation. It supports irregular channel geometries under steady uniform flow conditions, including circular and elliptical pipes. Flow Calc™ is widely used by civil engineers as an efficient tool for generating calculations and producing high-quality, professional reports.
As part of the continued commitment to helping users and engineers get the most out of Flow Calc™, visit the the Flow Calc™ YouTube Channel for training and tutorial videos.
Flow Calc™ is available through a subscription-based licensing model offered in non-recurring one-month and one-year terms. The subscription period begins at the time of purchase and provides access to the latest software updates, new features, ongoing improvements, and technical support. This licensing approach also helps support the continued development and enhancement of the platform. To provide greater flexibility, licenses may be transferred between workstations using the online License Management tool, making it easy to switch devices or work from different locations. Licenses are activated immediately upon purchase and provide instant access to the software. As a result, all purchases are final and non-refundable. Please review your subscription plan selection carefully before completing your purchase. Licenses are non-renewable and cannot be extended. To continue using Flow Calc™ after a subscription expires, a new license must be purchased for the desired subscription plan.
