This task allows you to model single open channels and closed pipe sections, with a variety of shapes and configurations. Quickly find the full-flow capacity as well as other flows through a range of depths. It provides graphs, grid-style numerical outputs, a rating table and formal printed reports. Studio Express also includes the ability to design channel widths, pipe spans and diameters based on a single known Q.<\/p>\n\n\n\n

An open channel is defined as a conduit for flow which has a free exposed surface. They typically include channels, streams, natural or man made or highway gutters and ditches. When water flows in a uniform channel it ultimately reaches and maintains a constant velocity and depth called Normal depth. The energy grade line (EGL) parallels the water surface (hydraulic grade line) because the energy loss is exactly compensated for by gravity. Studio Express uses Manning\u2019s equation to compute Normal depth.<\/p>\n\n\n\n

At normal depth, the slope of the invert of the channel or pipe is equal to the slope of the EGL… the S term in Manning’s Eq.<\/p>\n<\/blockquote>\n\n\n\n

The following channel shapes are available:<\/p>\n\n\n\n
