Book excerpt: Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial, floodplain, and subsurface environments, and 3) to determine if hyporheic water can be distinguished from true groundwater using water quality characteristics. Primary variables include free water surface elevation, temperature, and specific conductivity. Study sites were located within three effluent reaches of the unconstrained, fourth order upper Middle Fork John Day River in eastern Oregon. A significant association was observed between relative ground surface temperature and depth-to-groundwater at the three well fields. In addition, the ability of FLIR to predict shallow aquifers decreased as depth-to-groundwater increased. However, a high degree of variability was observed. Spatial aquifer water surface patterns varied between sites and appear to be influenced by hydrologic origin, including various groundwater, hyporheic water, and irrigation water sources. The net hydrologic flux into the river per meter depth at Well Field 3 was estimated at 4.2E-03 m3/s-m. Diurnal water surface elevation varied among wells and between wells and staff gages. Annual mean aquifer recharge was greatest during fall months while mean discharge occurred only during spring months. Mean annual aquifer temperature varied according to degree of connectivity between surface/subsurface environments. Subsurface aquifer temperature and specific conductivity patterns were not always correlated to water surface gradients. However, these variables may represent subsurface fluxes not apparent using water surface contours. An irrigation effect on aquifer temperature and specific conductivity may have influenced these variables. Mean percent saturation of dissolved oxygen was low in the wells and saturated in the Middle Fork. pH values were generally neutral in the aquifer and slightly alkaline in the Middle Fork. Water surface gradient provided the most reliable indicator of hyporheic water, followed by subsurface temperature and specific conductivity. Boundaries between groundwater, hyporheic water, and irrigation water appeared to exist as a gradient rather than an abrupt edge. However, environmental factors may also have influenced this relationship.

Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Book Synopsis Restoration of Aquatic Ecosystems by : National Research Council
Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

This book was released on 2004-01-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study.
