Book Hydrodynamics and Juvenile Salmon Movement Behavior at Lower Granite Dam Decoding the Relationship Using Three dimensional Space time CEL Agent IBM Simulation

Download or read book Hydrodynamics and Juvenile Salmon Movement Behavior at Lower Granite Dam Decoding the Relationship Using Three dimensional Space time CEL Agent IBM Simulation written by Richard Andrew Goodwin and published by . This book was released on 2004 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CEL Agent IBM for migrants at Lower Granite Dam, i.e., the Numerical Fish Surrogate (NFS), is developed from four independent CFD model and biological data sets from year 2000 studies. The NFS was then 'blindly' validated using seven independent CFD modeled flow conditions from year 2002 studies, i.e., with no prior knowledge of 2002 biological results. NFS predictions from the 'blind' validation runs were first compared to 2002 biological data by an independent entity. The NFS and embodied SVP Hypothesis capture 80% (r2 = 0.80) of the observed variation in 2000 and 2002 migrant passage and 85% (r2 = 0.85) of the observed variation in dawn, dusk, and nighttime passage, i.e., when migrant visual acuity is limited.

Book Influence of Water Temperature on Adult Salmon and Steelhead Passage and Behavior at Lower Granite Dam 2008

Download or read book Influence of Water Temperature on Adult Salmon and Steelhead Passage and Behavior at Lower Granite Dam 2008 written by T. S. Clabough and published by . This book was released on 2009 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Previous studies have identified Lower Granite Dam fish ladder as having as high temperature differentials during summer months. In 2008, we monitored water temperatures within the fish ladder and the passage of radio-tagged adult salmonids at Lower Granite Dam. Water temperatures in the fish ladder were cooler than in previous study years, with only five percent or less of all radio-tagged fish passing the dam when water temperatures differences between upper and lower segments of the fishway exceeded 1 °C. The warmest average monthly temperatures occurred in August and differences in temperature between the top and bottom of ladder the ladder exceeding 1 °C occurred on one day in July and one day in October. A significantly higher percentage of spring-summer Chinook salmon (O. tshawytscha) exited the fish ladder to the tailrace when temperatures exceeded 18 °C than when water ladder temperatures were less than 18 °C. We did not find differences in the percent of steelhead (O. mykiss) and fall Chinook salmon that exited the ladder when temperatures were greater than or less than 18 °C. Median dam and transition pool passage times were higher for all runs of radio-tagged fish when water ladder temperatures exceeded 18 °C. Most tagged fish that exited the dam to the tailrace did so after reaching the transition pool area of the ladder regardless of temperature. We found a higher percentage of fish overnighted when water temperatures were greater than 18 °C. Since 2008 was a relatively cool year, future studies may be needed to more effectively evaluate the relationship between fish passage and temperature gradients within the fish ladder at Lower Granite Dam."--Abstract.

Book Innovations in Fish Passage Technology

Download or read book Innovations in Fish Passage Technology written by Mufeed Odeh and published by . This book was released on 1999 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Odeh (Conte Anadromous Fish Research Center) presents 13 contributions which explore the technical possibilities of constructing effective fish bypass systems for hydroelectric dams, especially those that are due for relicensing in the context of new regulations. The articles consist of case studies in the effectiveness of such techniques as surface bypass systems, modular inclined screens, hydroacoustic evaluation of fish entrainment patterns, surface collection, surface spill gates, and radio-tagging and radar tracking behavior evaluation strategies.
