Join fellow hydroacoustics enthusiasts in this beloved annual session to find out who made the largest measurement in WY25 and other interesting tidbits.
Remote control (RC) boats are increasingly used to deploy acoustic Doppler current profilers (ADCPs) for streamflow measurements. These platforms can enhance safety, reduce operational costs, and improve field efficiency. However, they also introduce potential data quality concerns. Additional quality assurance is required to detect and mitigate issues such as electromagnetic interference, air entrainment, and flow disturbance. This presentation will outline the advantages and limitations of RC boat based ADCP deployments, present examples of both high and low quality datasets, and highlight practical steps users can take in the field and during post processing to address common data quality challenges.
Small changes in an ADVM position can cause big problems with your index velocity rating. Changes in pitch and roll can change from poor mount design, broken mounts, debris snags, or ADVM installation error. When pitch and roll changes occur, a different sample volume is measured which can cause departures in your index velocity rating. ADVM movement could be difficult to catch, but reviewing ADVM data in the field can explain and potentially prevent rating issues. This talk will discuss how to identify rating problems caused by changes in pitch and roll along with best practices for shifting index velocity ratings due to pitch and roll.
Join us for a focused 10-minute presentation highlighting the latest research and development initiatives from Hydroacoustic Working Group (HaWG). Following this, attendees will engage in a dynamic 40-minute open forum, offering the chance to connect directly with HaWG experts, ask questions, and share your operational needs. Don’t miss this opportunity to gain valuable insights and support from the leading voices in hydroacoustics.
QRevMS is an application used for processing and reviewing ADCP midsection discharge measurements. Like QRev, QRevMS processes data loaded from the manufacture data files using automated quality checks and data filtering. This talk will discuss the workflow of the application, specifically related to post-processing and measurement review. Improvements and updates to the software will also be discussed.
