397921 - Artificial Pools Along River Channels and Upstream Migration of Adult Chinook Salmon to Spawn

Wednesday, June 6

Location: Greenway GH

River restoration projects have focused on restoring the heavily managed river systems to their natural or pristine systems. In restoring San Joaquin River in the Central Valley, California, the water users and the environmentalists entered into a legal agreement where certain quantities of water are to be released from Millerton Lake, California, depending on the type of water year. However, it was found that the water released during the dry years may not be sufficient for the adult Chinook salmon to migrate upstream along the San Joaquin River to areas close to the Friant dam to spawn. Further, small pools along the river channel have been found to provide habitat for juvenile salmon. The objective of the work is to investigate whether constructing artificial pools along the river channel would provide safe habitat for the adult salmon on its journey to spawn. This paper will present results of two scenarios, one for dry year 2012 and the other for wet year 2017, for temperature along the depth in the artificial pools. The study area is the upper 40-mile reach of the San Joaquin River, from Friant Dam to Gravelly Ford. Modeling results from CE-QUAL-W2, a two dimensional, hydrodynamic – water quality model developed by the US Army Corps of Engineers, will show the variation of temperature along the depth for the two cases. It will also discuss possible engineering solutions to improve the pool temperature.

As a researcher, teacher and as an engineer I have been working in the field of Hydraulics, Hydrology, and Water Resources engineering for more than twenty years. I have designed, constructed, and restored water resources systems for the benefit of both people and environment – water treatment systems and irrigation systems; carried out water quality and water quantity data collection to create wetlands; conducted a novel laboratory study (floating solid method) to determine the reaeration rate coefficient an important factor in maintaining a healthy eco system; designed and carried out physical and mathematical modeling studies to assess sedimentation in hydropower reservoirs; and developed and introduced for the first time a new course in West Virginia University, Advanced Topics in Erosion and Sediment Transport. During a short period, I practiced law and gained an understanding of the interaction of the legal system with water resources. Recently, I was investigating methods to provide water for maintaining a suitable habitat for Chinook salmon in the regulated San Joaquin River. Recently, taught Water and Waste Water Treatment and Climate and Hydrology at University of California - Merced. With the impending climate change, I like to move into Integrated Environmental Resources taking into account the various sectors: energy, quality, scarcity, and ecology. Finally, as a multilingual water resources engineer with education and work experience spanning several countries (Colombia, Ecuador, Germany, Malawi, Nigeria, Panama, Sri Lanka, and the USA) I can easily adapt to the diverse cultural settings and will go out of my way to support them in completing a project.
