According to the Federal Highway Administration (FHWA) scour is the leading bridge failure cause in the United States. According to the National Bridge Failure Database, 58% of bridge failures in the US are due to hydraulic conditions.

· Small Size and Light Weight
· Being Usable in Different Kinds of Materials: Can be used on steel, concrete, timber and composites
· Rugged and Weatherproof Device:  Can operate in rain, snow, ice, high humidity and extreme weather (-40°C to +65°C or -40°F to+150°F).
· Long Communication Range: 1 km free space.
· Rugged, Weather Proof andCorrosion Resistant: Can operate in rain, snow,ice, high humidity, salty environment and extreme weather (-40°C to +65°C or-40°F to +150°F).
· Infrastructure-less: Battery Operated, Energy self-sufficient, No need forcommunication infrastructure at the bridge
· Non-contact Distance/Level Measuring (Water Level Meter).
· High Precision for Wireless Water Level Meter: Resolution 0.1ft. or 3cm
‍· Very High Resolution for Wireless Tilt Sensor (Inclinometer): 0.00016 degree or 0.5 arcseconds

Right: unhealthy tilt caused by hydraulic damage, non-returned tilting.

This system reduces installation cost and time for owners / authorities to get the realtime data they need for scour critical bridges monitoring. A unique capability of Resensys wireless gauges (Water Level Meter, and Tilt Sensor) is to measure at very high precision, while providing ultra-low power usage to allow for short and long term monitoring. The measurements can be combined with Wireless Solar Powered Camera corresponding visual feeds to get complete condition awareness and remote monitoring on scour critical bridges, and is particularly useful to allow quick assessment of conditions after severe floods.

A typical Scour Bridge Monitoring system includes the following components:
‍Wireless SenSpot™ Sensors and Devices: These are attached to the scour critical prone members of a structure. The number of gauges required per structure is usually dependent upon the design, existing issues on members and scour critical bridge monitoring needs.

SeniMax™: SeniMax^TM is a wireless data logger gateway that is connected to the cellular or satellite networks. It wirelessly collects SenSpot™ data at the site and sends it to a cloud database server (one SeniMax™ can cover as many as 100 SenSpot™ sensors and devices within its wireless communication range).
‍
SenScope™: SenScope^TM is a software for data analysis, visualization, data export, automated alert management, thermal analysis, and scour critical bridge data analysis. For scour critical bridge monitoring, Resensys SenScope™ has the feature to provide alert notifications when pre-set data thresholds have been exceeded (by sending warning email/text/notification to corresponding authority).
