The LabView Enabled Watershed Assessment System (LEWAS) is a unique real-time water and weather monitoring system that has been developed as a result of several NSF grants (examples: NSF/DLR; NSF/TUES; NSF/REU Site) to enhance water sustainability education and research at Virginia Tech. LEWAS is installed at the outlet of Webb Branch on the VT campus just off of West Campus Drive, downstream of the Perry Street Parking lots and just upstream of the Duck Pond. LEWAS has sensors to measure water quality and quantity data including flow rate, depth, pH, dissolved oxygen, conductivity, and temperature. This data can be used as an indicator of stream health for an on-campus impaired stream in real-time. In addition, weather parameters (temperature, barometric pressure, relative humidity and precipitation) are measured at the LEWAS outdoor site. All of these environmental parameters can be accessed by remote users in real-time through a web-based interface for education and research. LEWAS is solar powered and uses the campus wireless network through a high-gain antenna to transmit data to remote clients in real-time.
- The LEWAS Research Lab Team
Earlier this month the LEWAS team removed SonTek’s Argonaunt Flow Meter from the bottom of Stroubles Creek. For the past month the flow meter has been not been providing accurate data for the LEWAS team. The picture bellow depicts the Argonaunt installed on the bottom of the creek.
When the electrical and computer engineering (ECE) team opened the Argonaunt to perform a general investigation and hardware debugging they found a leaking seal and corrosion of parts inside of the flow meter. The white internal connection bellow has extensive corrosion inside of it. The ECE team is deterring if these parts can be replaced.
