An Investigation Of The Hydraulics In A Prototype Pool-And-Chute, Vortex Weir Fishway For Anadromous Fish Passage., Brendan Foster
Cal Poly Humboldt theses and projects
This thesis presents the hydraulic characteristics and simulated passage efficiency of a hybrid pool-and-chute, vortex weir fishway designed by Michael Love & Associates. A physical 1:15 scale model was constructed and evaluated at an 8% slope over three prototype flow rates representing high and medium fish passage flows. The highest velocities and turbulent kinetic energy (TKE) values were concentrated along the fishway centerline at the high and medium flow rate and the pool sides showed lower velocities and TKE. Large eddies spin laterally and longitudinally throughout each pool. The velocity vector directions at the lowest flow rate measured differed from …
Assessment Of Individual Photovoltaic Module Performance After 26 Years Of Field Exposure At The Telonicher Marine Lab In Trinidad, California, Jake Rada
Projects
In 1990, 192 ARCO M75 photovoltaic (PV) modules were installed as a part of the Schatz Solar Hydrogen Project at the Humboldt State University (HSU) Telonicher Marine Lab in Trinidad, California, within 150 m of the Pacific Ocean. This 9.2 kW-rated PV array was used to power the marine laboratory air compressor and an electrolyzer. Individual current-voltage (IV) curve tests were performed on each of the PV modules prior to the array’s construction in 1990 and again in 2001, 2010, and, most recently, in 2016, following decommissioning of the array. After 25.5 years of use, 188 of the original 192 …
