About Studio Express

Welcome and congratulations for choosing the industry’s most easy-to-use hydraulics & hydrology software. This state-of-the-art desktop application was designed to be a quick and easy tool for solving everyday hydraulics and hydrology problems. It features open channels, pipes, weirs, orifices, HEC-22 -style inlets and hydrology. All of this is wrapped around a rich user interface built from the ground up with Windows Presentation Foundation.

Who uses Studio Express?

Studio Express was developed primarily for practicing civil and environmental engineers, engineering students, educators and related professionals involved with fluid mechanics, drainage hydraulics and runoff hydrology.
