Abstract: Emerging cyberinfrastructure-based decision-support systems for aquatic environments assume coupling of real-time monitoring instruments with data-driven models covering spatial and temporal scales from microhabitat to watershed levels. This paper describes a Mobile Large-Scale Particle Image Velocimetry (MLSPIV) mobile unit that allows visualization and quantitative measurements of instantaneous and averaged flow characteristics in rivers over large areas. The unmatched spatial resolution along with the remote, real-time, and fully digital nature of LSPIV makes it an ideal cybertool either as a stand-alone instrument, as presented in the paper, or integrated in large-scale networks. Preliminary tests with similar stationary LSPIV configurations proved that the technique is reliable, flexible, and efficient for monitoring, design, hazard warning, and decision-making in riverine ecosystems. The discharge measurement results using MLSPIV show good agreement to the value from the USGS stream gaging station.
