Clavey confluence timelapse

This past spring, UC Davis researchers installed time lapse cameras, water stage recorders, and temperature monitoring equipment in both the mainstem Tuolumne River (regulated by Hetch Hetchy Project facilities - particularly Holm Powerhouse) and the Clavey River (an unregulated tributary to the Tuolumne) near their confluence.  Video gurus at UC Davis then layered the time lapse video, stage, and temperature data of both rivers, providing a visual comparison of temperature and hydrology dynamics in the regulated and unregulated streams. This work is part of a larger UC Davis effort to learn more about how tributaries and stream confluences affect hydrology and geomorphology.  Watch the video in HD on Vimeo for best effect, and to learn more about how the video and data were compiled.
