The RLS non-contact radar level sensor with pulse radar technology is ideal for monitoring in remote areas and applications where conventional measuring systems are not suitable. The RLS accurately and efficiently measures surface water level With a non-contact distance range of up to 115 feet above water. The sensor is IP67 waterproof and has extremely low power consumption, making it ideal for solar-charged monitoring systems.
The radar level sensor uses a revolutionary level measurement technology, meeting the USGS accuracy requirement of +/-0.01 feet. Two antennas are enclosed in a compact housing and transmit pulses toward the water surface. The time delay from transmission to receipt is proportional to the distance between sensor and water surface. A sampling rate of 16 Hz (16 measurements/second) with 20 second averaging minimizes water surface conditions such as waves and turbulence. The RLS does not require calibration and is unaffected by air temperature, humidity, flood events, floating debris, or contaminated water.

Extreme Wave Heights, Ocean Winds Increasing Globally
Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work. “Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.” Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean. “The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.

Measuring Rising Floodwaters with the USGS
All year long the US Geological Survey (USGS) in North Dakota and South Dakota monitors water levels, but during times of flooding, all eyes are on the team. EM spoke to USGS data chief Chris Laveau about the monitoring efforts. “The US Geological Survey in North Dakota and South Dakota is one entity, so we monitor the flooding in both states,” explains Mr. Laveau. “The role is to provide continuous information on water level, we call that gauge height or stage, and we also provide continuous information at a lot of locations on stream flow, typically called discharge. We do that year round but, obviously, during a flood event it garners more attention.

Tide Gauge Data Reveal Multiple US Meteotsunamis Annually
Say the word “tsunami” and images of tremendous waves engulfing homes or masses of debris might come to mind. Those tsunamis that are triggered by massive landslides and earthquakes are in fact at that scale. But weather can trigger more localized “meteotsunamis” as well, and new research shows just how common these are along the East Coast of the United States. National Oceanic and Atmospheric Administration (NOAA) physical oceanographer Gregory Dusek of the National Ocean Service in Silver Spring, Maryland, spoke with us about the work. “The public noticed the 2013 tsunami event, we did a report summarizing that event in our office, and we started wondering how frequently these actually occur,” explains Dr. Dusek.
