Weir flow measurement is a fundamental hydraulic technique used to estimate channel discharge by relating the upstream water level (stage) to the flow rate. The stage-discharge relationship, central ...

The current standards recommend measuring water discharge with vented thin-plate weirs. The ventilation of full-width, thin-plate weirs during discharge hydrograph measurement still poses a problem.

A study was performed to develop a method whereby discharge in a partially full sewer could be determined from a depth measurement and a velocity measurement at a single location on the vertical ...

“Lightweight, compact, powerful and easy to handle” were the criteria when the engineering team of BAUR GmbH were developing the new device - PD-TaD60 - for partial discharge measurement and location.

This paper describes OpenOpticalFlow, an open source optical flow program in Matlab for extraction of high-resolution velocity fields from various flow visualization images. This program is a useful ...
