RiverSurveyor vs HydroSurveyor: What's the Difference?

  Ever heard the common Thai phrase – “Same, same but different”? Well this applies well to the SonTek RiverSurveyor-M9 and HydroSurveyor-M9, albeit literally. Same hardware, but very different firmware, software and application between the two. Join Product Manager Isaac Jones in this short video as he summarizes the main differences. If you have questions about which is the best for your application, which one to measure river velocity and discharge or map bathymetry, Isaac clears up the differences in this video.

2018 Wilmington North Carolina Oceans & Coastal Workshop

  SonTek, as well as the other brands that represent the Xylem Analytics family often host training events that allow for water monitoring professionals the chance to get "up close and personal" with some of the latest water monitoring technology available. Our Application Engineers travel the world sharing their knowledge in the goal of helping hydrologists, hydrographers, oceanographers, research scientists and all those collecting water data to make smarter, and defensible, conclusions.

RiverSurveyor 4.0

The New Standard in Collecting Acoustic Stationary and Moving Boat Discharge Data
  RiverSurveyor 4.0: The new standard in collecting acoustic stationary and moving boat discharge data You might have heard about some of the big upgrades to the powerful, multi-frequency RiverSurveyor-M9, but we didn’t want you to take our word for it – the proof is in the data – and we want to share examples on how RiverSurveyor 4.0 has dramatically simplified the data collection process for hydrologists and water monitoring specialists like you!

Aquaculture, reef studies, sediment transport and more - Choose the right ADV and use it like a pro!

  The first Acoustic Doppler Velocimeter (ADV) was introduced to the scientific world by SonTek in 1993. It was used primarily in lab environments for controlled studies requiring highly precise single point water velocity data.

Over the years, the ADV family of instruments grew, as well as the locations in which they were being used. Today, while you can still find ADV’s as a standard part of any university hydraulic lab arsenal, you can also find systems actively being used for coastal wave studies, estuarine research and river/stream flow modelling.

A Week in the Life of Jon Kneier

Talent and technology in San Diego
  Ever wonder what it might be like to work as an Engineer at SonTek? Here’s a peek inside walls of our San Diego manufacturing facility as we continue our “Week in the Life of” series featuring our very own Jon Kneier!

Introduction to GPS Positioning for RiverSurveyor Stationary Live Measurements

  The RiverSurveyor-M9 can be used for both the Moving Boat or Stationary discharge measurements. The stationary measurement method applies the velocity area method using either the Mid-Section or Mean-Section methods for discharge calculations. The measurement of the water depth and velocity profile at individual stations has greatly improved since the introduction of Acoustic Doppler Instruments. SonTek has gone one step further by implementing GPS in RiverSurveyor Stationary Live software to determine the station locations from GPS positioning. This method improves the measurements process, efficiency and accuracy from the traditional measuring tape or tagline methods.

A Week in the Life of SonTek Application Engineer Xue Fan

  It’s an exciting job when you get to work with some the most sophisticated environmental water monitoring instrumentation in the world, and help researchers, scientists, engineers, oceanographers and hydrographers collect crucial data to assist in making smart water management decisions.

SonTek Application Engineers do just that – and while their role as developers and educators is in constant flux, it’s a daily adventure – as you’ll see in this short video where we take a look in the day in the life of one of our field specialists, Dr. Xue Fan!

RiverSurveyor-M9 on the Ebro River – Zaragoza, Spain

  This drone video features one of two transects undertaken by the RiverSurveyor-M9. The demonstration was part of a SonTek workshop. Attendees included SAIH Guadiana, SAIH Jucar, SAIH Ebro, and the Navarra Region Government. The Q was well within monitoring agencies’ 5% acceptance level. The river gauging station and control room is managed by the Confederacion Hidrografica del Ebro.
