Hydro-STIV Cloud

Flow velocity and discharge measurement software using video footage

「Hydro-STIV Cloud」 is a flow velocity and discharge measurement system that uses video images and water level information. In addition to basic functions for measuring flow velocity and discharge, it is equipped with the latest measurement technology, such as a function to correct the wind effects and a function to calculate velocity distribution of cross section.

Intuitive and easy to measure.
The measurement results can be output to an HTML report.

AI Enables High-speed and High Accuracy Measurement

AI(Deep learning) enables more stable measurement than conventional methods, Highly accurate measurement can be performed with complete automatic analysis even when obstacles are in the image, when there is muddy water and heavy rain with high water, when there is a reflecting light at night infrared camera is used.

Comparison of flow velocity and discharge measurements by ADCP(Acoustic Doppler Current Profiler)and Hydro-STIV has confirmed that the measured discharge of the two differ within about 5%
