• Feasibility of Multiple Camera Large Scale Particle Image Velocimetry Techniques for Rivers In Alaska

Alaska is characterized by spare hydrologic data. Non-intrusive gauging is one method of increasing the data available, but is limited in its current application. This study seeks to assess the feasibility of using commercially available software to diversify the conditions that Large Scale Particle Image Velocimetry (LSPIV) may be applied. Through the use of available software and the deployment of multiple cameras; stereoscopically determined discharge is compared to Acoustic Doppler Current Profiler and accepted single camera practices currently in use with LSPIV. The results indicate that the use of multiple cameras is feasible, with additional work, and that there is a statistically significant relationship between the velocity index (α) and the geometry of the river (B/H, width divided by average depth). The alpha-geometric data indicate that the velocity index is a result of the environmental and geometric conditions for a given cross section and an empirical relationship could be established.

We are excited to combine Erice LeMesjerant's MS defense with a WERC Seminar.
