<p>Working with the tides—especially in a system that is half aquatic—requires a close eye on water flow. Delta Coast Consultants worked with Xylem to install suites of monitoring instruments on both sides of its many barge
gates. These stations provide data on parameters like water level, velocity, flow and direction, and wind speed and direction. These data are transmitted every six minutes to the levee district's command center.</p>

Our instruments use sound waves to tell you how fast water is moving, where it is moving, and even if it is not moving. Our customers are scientists, engineers, hydrologists, research associates, water resource planners, and anyone that needs to collect velocity, flow, or discharge data in every kind of body of water imaginable. INSTANTANEOUS MONITORING An Instantaneous Measurement is taken out into the field for a measurement of the current velocity and/or flow conditions. Select any one of these instruments to learn more about their ideal applications and technical specifications. SonTek-RS5: Robust data from the world’s smallest ADCP. RiverSurveyor M9: Award-winning, multi-frequency discharge or bathymetric data collection ADCP. FlowTracker2-ADV: Trusted handheld wading discharge Acoustic Doppler Velocimeter. FlowTracker2-ADV: Handy and flexible option for hydraulic research projects. CONTINUOUS MONITORING Looking for a long-term data collection solution? Our Continuous Monitoring instruments allow for permanent to semi-permanent installations for collecting water velocity and/or flow measurements on a regular, user programable time interval. SonTek-IQ Series: Monitor flow in canals, culverts, pipes, and natural streams. SonTek-SL Series: Convenient side-mounted system doppler for velocity and level data. Argonaut-XR: Simple deployment for nearshore monitoring. CONDUCTIVITY TEMPERATURE DEPTH An industry favorite! The handheld CastAway®-CTD is a lightweight, easy-to-use instrument designed for quick and accurate conductivity, temperature, and depth profiles. CastAway-CTD: The user-friendly, handheld, castable instrument for CTD profiles. FEATURED VIDEO DAY IN THE LIFE OF A HYDROGRAPHER, WITH KEVIN LABBE Hydrographers, Hydrologists, Research Scientists (and more) work to understand better water properties and distribution are paramount to making sure this resource is sustainable well into the future. Please take a look at a day in the life of Application Engineer Kevin Labbe. He helps researchers from the University of Georgia learn how to best use the SonTek RS5 ADCP, YSI's EXO2, and other instrumentation in the estuaries of Little St. Simons, Georgia. GLOBAL APPLICATION SUCCESS STORIES TINY ISLAND, BIG INSIGHTS At just 11,000 acres, Little St. Simons Island is a tiny squiggle on most maps. But its subtle uplands—just 10 to 12 feet above sea level at best—and sprawling wetlands present a big opportunity to study coastal dynamics. And big questions drive research on this small Georgia Island. Read More HYDROSURVEYOR ENABLES RAPID INDIAN RAILWAYS BRIDGE SURVEYS Flood events on rivers can cause erosion of the soil around a bridge foundation. This process is referred to as bridge scour. Over time, scour can cause dangerous foundation instability and is the leading cause of bridge failure. Acoustic technology makes railways safer. Read More RESEARCHING CLIMATE CHANGE WITH CTD MONITORING TECHNOLOGY A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which used SonTek’s CastAway-CTD, could cast new light on our understanding of the ways in which shifting ocean currents impact the climate in northern Europe. Read More STREAMFLOW DATA IMPROVE GREENLAND ICE MELT MODELS A multidisciplinary team of hydrologists, climate scientists, and modelers led by UCLA geographer and geologist Laurence C. Smith use the RiverSurveyor-M9 in Greenland Ice Sheet rivers to ground truth runoff model predictions. Read More REEF RESILIENCE: SCIENTIST SURFER STUDIES CORAL REEF SURVIVAL Before Dr. Cliff Kapono shifts his research to the stage of sampling and analyzing microbiota from the reef, he characterizes the flow of water and sediment throughout the water column. His tool is a SonTek CastAway-CTD, which measures conductivity, temperature, and depth at a rate of 5 Hz, then calculates salinity, sound speed, and other parameters. Read More CLEVER KAYAK RIG NAVIGATES TRICKY BATHYMETRY CHALLENGE Bret Webb of the University of South Alabama is a master at cobbling together clever solutions in challenging situations. When he realized he couldn’t launch his instrument-laden JagSki watercraft at Lake Forest, he rigged a bathymetry-surveying kayak—the JagYak. Read More MONITORING AND INGENUITY HELP LOUISIANA COMMUNITIES BATTLE STORMS Working with the tides—especially in a system that is half aquatic—requires a close eye on water flow. Delta Coast Consultants worked with Xylem to install suites of monitoring instruments on both sides of its many barge gates. These stations provide data on parameters like water level, velocity, flow and direction, and wind speed and direction. These data are transmitted every six minutes to the levee district's command center.
