Integration of a Real-Time Water and Weather Monitoring System into a HydrologyCourseThis paper will discuss the authors’ experiences in integrating a real-time water and weathermonitoring lab, called the LabVIEW Enabled Watershed Assessment System (LEWAS), into asenior level hydrology course at a large public university. LEWAS uniquely integratesLabVIEW’s data acquisition capability with the water and weather hardware. Specifically, itincludes a Hydrolab sonde which collects water quality data, an acoustic doppler flow meterwhich measures flow and stage of the stream, and a weather data collection station at a creekthat flows through the campus.The goal is to enhance student learning by incorporating LEWAS-based hands-on modules.Three learning modules were developed and implemented: (i) Storm Characteristics Module:Data collected at the outdoor site of LEWAS, were used to discuss the rainfall-runoffrelationship in a small urbanized watershed. Analysis tasks for a particular stormincluded determining the baseflow, the volume of rainfall and runoff, and the runoffcoefficient. (ii) Land Cover-Water Quality Correlation Module: LEWAS’ capability allowsstudents to learn about the relationship between land cover and water quality based onthe constituents being measured. Detailed digitized land cover and storm quantity andquality data were analyzed to show how water quality and land cover are related. Thismodule allowed students to critically think about the relationship of land cover and waterquality through the use of local, long-term data. (iii) Watershed Wiki Module: LEWASwas employed to motivate students about the importance of monitoring our sustainableresources. Two of the most important advantages of LEWAS are that it is monitoringthe watershed in which the classroom is located, and that the data is web-accessible.This module entailed assigning teams of students throughout the semester to visit theoutlet monitoring site and write daily reports on the class Wiki about the unit’sperformance and the monitoring results. The groups acted as the watershedassessment team for the assigned week, preparing data tables and graphs for weather,flow, and water quality.Student perceptions are documented using pre-and post-test survey instruments, andlessons learned are documented. This project is supported under the NSF TransformingUndergraduate Education in STEM (TUES) Program.
