Insights and Challenges in Developing a Remote Real-Time Watershed Monitoring LabThe LabVIEW Enabled Watershed Assessment System (LEWAS) is a remote real-time watershedmonitoring lab in Stroubles Creek on the campus of a large public university. The lab is comprised of aninterdisciplinary group of researchers focused on developing an automated watershed monitoring lab withreal-time data accessible to a wide range of users on an easy to use internet-accessible platform.Watershed monitoring hardware including a water quality multiprobe, acoustic doppler flow meter,weather station, and outdoor camera are integrated together using LabVIEW software to providecontinuous real-time watershed data.There have been many unique challenges in developing and implementing a remote real time watershedmonitoring lab. Examples include collecting accurate precipitation and flow data, and developing routinemaintenance and calibration procedures. To verify the accuracy of precipitation data, a tipping bucket raingage has been installed at the site to provide additional rainfall data and develop calibration curves for theweather station. Collecting consistent and accurate flow data in a unique urban watershed has requiredmultiple instruments and flow computation techniques. An acoustic doppler flow meter installed at theLEWAS site provides flow data through an index velocity to discharge relationship. A secondary flowmeasurement is provided by a weir installed in a culvert directly upstream of the site, where an ultrasonictransducer will soon be installed to provide stage data. Finally, maintaining accurate and reliable data forall instrumentation has required developing calibration and maintenance procedures which prevent errorsin data collection and ensure equipment upkeep. Data from this lab is being used in multiple courses at alarge public university including a senior level Hydrology course as well as in freshman level courses at acommunity college.
