Measuring River Discharge – The Great Mississippi River Flood of 2011

By mlynch | |

Measuring River Discharge is a common project as the Gulf South representative of Teledyne RD Instruments. We are often called in to support important measurements. During the record flood event in spring 2011, we demonstrated the capability of the RDI RiverRay ADCP for the USACE ERDC. Their local support consultant Dimco, needed a capable Acoustic…

Flow Measurement at an Industrial Outfall Using the Index-Velocity Rating Method

By bdalton | |

Channels with a large depth to width aspect ratio present a challenge when it comes to accurately measuring flow rates in real time. The index velocity method provides a solution for real time flow rate reporting in situations where traditional stage-discharge ratings are not possible. The index velocity method uses a mathematical model to calculate…
