This book was released on 2011-01-06 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discusses the history of the U.S. Bureau of Reclamation's operation and management of the Colorado River on behalf of the Secretary of the Interior from 1979 through 2008. Details the political, legal, institutional, and other instruments developed to address pressing issues faced by Colorado River Basin water users and managers. Reflective of its era, the 2008 volume has an increased focus on coordinated operations of the river in both the Upper and Lower Basins, on environmental matters, on the relationship with Mexico, and on Native American water settlements.

Available in PDF, EPUB and Kindle. Book excerpt: Instantaneous amounts of organic carbon, both particulate and dissolved, in a number of freshwaters ranging from unproductive tarns to moderately productive reservoirs were measured by acid-persulfate digestion and infrared absorption. Organic carbon was designated as net seston carbon, filter seston carbon, or dissolved carbon based on filtering techniques. Repeated sampling showed amounts of organic carbon, either dissolved or particulate, fluctuated considerably over short periods of time; the dissolved fraction probably varying less than particulate forms. Almost daily measurements in samples incubated over three week periods also revealed erratic changes, with no clear reduction in total organic carbon. The data have descriptive value, although they cannot, at this time, be related satisfactorily to the general limnological knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: Rivers transform, mineralize, and export organic carbon and are a substantial portion of regional and global organic carbon (OC) budgets. Quantifying the drivers of OC transformation and mineralization are needed to understand how rivers export OC to downstream ecosystems. A substantial flux of OC in rivers is dissolved organic carbon (DOC). DOC sources and fates in large rivers, which drive riverine fluxes, are poorly understood. Furthermore, reservoirs decrease OC export by trapping particulate organic carbon (POC), but the effect of reservoirs on DOC export is less clear. Tailwater ecosystems directly below dams are fundamentally different than reaches upstream of reservoirs, but how these ecosystems alter OC export is less understood. I conducted three studies with the overall objective to quantify source specific fluxes of organic carbon in the Colorado River Basin. I quantified autochthonous DOC in a tailwater ecosystem as a focus of my first chapter. Few studies have focused on source specific fluxes of DOC, especially autochthonous DOC. I found that although the flux of autochthonous DOC was 7% of the total DOC flux, it was a 43% of gross primary production. Therefore, autochthonous DOC can contribute to daily DOC budgets and a large fraction of primary production in tailwater ecosystems. In chapter 2, I quantified sources and fates of DOC in the Grand Canyon reach of the Colorado River. Because sources and fates of DOC are empirically difficult to measure in large rivers, I developed a model to estimate source specific fluxes of DOC, including influx and uptake rates of DOC. Using a transport model along with a Bayesian approach, I was able to quantify fluxes of algal and terrestrial-derived DOC. The influx of algal-derived DOC was 2X greater than the influx of terrestrial-derived DOC. Terrestrial-derived DOC was piped and exported downstream. Algal-derived DOC uptake rates were similar to DOC uptake rates empirically measured in streams 1000-fold smaller than the Colorado River, Grand Canyon. The modeling approach I developed can be used to quantify sources and fates of DOC in rivers where otherwise empirical measurements are not possible. In chapter 3, I estimated OC fluxes along with DOC composition and quality to quantify how OC export changed from free-flowing rivers to reservoirs to tailwater ecosystems. I found that reservoir-tailwater ecosystems alter the sources of OC from more terrestrial to more algal-like. The OC transformation from terrestrial to more algal-like may lead to underestimation of the quantity of terrestrial OC that was buried in reservoirs because total fluxes of OC did not represent transformation processes of OC in river-reservoir-tailwater ecosystems.
