The Learning Enhanced 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.

Despite the brown hairy algae, the LEWAS field site hosts a variety of plant and wildlife species. The algae here actually gives these marble sized eggs a perfect hiding space.
Maintaining a Clean Field Site
There have been great amounts of sediment and debris at the LEWAS field site from storm water this week. With only a few leaves left on the Sonde rack, regular site maintenance is in full force as the fall semester begins.
