Download or read book Leighton s High Sierra Check Dam Legacy written by Steve D. Bowman and published by Xlibris. This book was released on 2006 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This photographic journal chronicles the history and construction of the high Sierra check dams from the first one at Yellowhammer Lake in 1920 through the last one constructed at High Emigrant Lake in 1951, past the establishment of the Emigrant Wilderness in 1975, and through various stages of support and opposition which are on-going to this day. Each major period in either check dam construction or the period after is divided into separate chapters, with each check dam described in detail with historical and recent photographs, many that have never been published. In addition, available historical writings and records of Fred Leighton and others were utilized to provide a more in depth perspective on the check dams from those directly involved in construction and/or maintenance. Outdoor enthusiasts discovering the Emigrant Wilderness of the high Sierra for the first time might easily consider it a pristine wilderness, rich in wildlife, streams, lakes, and scenic views. And yet, this is one area where the hand of man has worked to enrich the natural landscape. One of the most notable changes man has made in this area is the construction of small rock dams at the outlet of selected lakes and meadows. These dams were called check dams by Fred W. Leighton, who developed the concept of raising the water level of natural lakes and meadows for fishery and riparian enhancement. These check dams provide an enhanced habitat for mountain fish by providing additional water flow in the late summer months when natural streams typically run very low or completely dry.
Download or read book Check Dams Morphological Adjustments and Erosion Control in Torrential Streams written by Carmelo Consesa Garcia and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Check dams are a potentially effective instrument for planning of hydrological risks and soil conservation. Cross structure sequences have been used in numerous areas in the world to control flooding, recharge aquifers and stabilise mountain streams, gullies and high-gradient ephemeral channels. Nevertheless, it is little known of the effectiveness of check dams and their morphological effects. This book is an attempt to compile different based-field and laboratory research works in torrential head water areas. Bed stability variations will be investigated according to check dams types, bedrock control, bed slope, channel roughness, lateral sediment input, and highly variable sediment transport capacity. Though the main purpose of check dams is to stabilise the channel bed and diminish the boundary sheer stress reaching a minor longitudinal slope, they can reduce the volume of channel-stored material favouring local scour processes downstream and occasionally destabilise the hill slopes upstream.

This book was released on 2022-08-16 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND PLANNING Authoritative and comprehensive reference on the potential for watershed development through the use of check dams Check Dam Construction for Sustainable Watershed Management and Planning summarizes current knowledge of check dams as key soil and water conservation structures in some of the most sensitive and vulnerable ecosystems in the world, as exemplified by the Mediterranean area and the Chinese Loess Plateau, providing detailed information on check dam design and watershed planning, the use of advanced modeling techniques, challenges in dam construction and how to overcome them. The work integrates decades of research in the field of soil and water conservation and gully management, including advanced studies in check dam construction and watershed management. It also covers important new techniques and methods, such as hydrological modeling, isotope tracing, and more. To aid in reader comprehension, the five highly qualified editors have divided the work into three distinct sections. Sections I and II focus on the experience gained from the erosion hotspots in the Chinese Loess Plateau, whereas Section III expands the scope to other regions with different functions for check dams, including headwater ecosystems and alpine environments. Sample topics covered in Check Dam Construction for Sustainable Watershed Management and Planning include: The regulating effect of check dam systems on sediment redistribution and the formation and development of dam systems in small watersheds Water and soil conservation made possible by check dam construction and sediment source analysis of water-sediment retarding effects of check dams The regulation of check dam systems on the erosion dynamic process and the mechanism of erosion reduction by check dams Flood control risk assessment on warping dam systems and the development and utilization model of check dam systems With its systematic coverage of all aspects of dam construction and maintenance, Check Dam Construction for Sustainable Watershed Management and Planning supports decision making by local authorities and can also be used as a professional guide for ecologists, hydrologists, and water resource managers.
Download or read book The Dams and Water Management Systems of Minoan Pseira written by Philip P. Betancourt and published by INSTAP Academic Press. This book was released on 2012-12-31 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excavations at the Bronze Age seaport on Pseira Island uncovered the remains of sophisticated water retention systems that included the addition of retaining walls to prevent erosion, massive dams with associated reservoirs, and small check-dams to ravines that reached over one hundred meters in length in order to control water runoff and make it available for human use. Agriculture was one of the cornerstones of the Bronze Age Cretan economy, and it is no surprise that the ancient inhabitants of the island went to great lengths to control water runoff and make it available for human use. Despite the application of traditional archaeological survey methods, the full extent of the water management systems was not understood fully as the island's rugged topography prevented intensive and thorough survey of many places. The use of a differential Global Positioning System (dGPS) unit provided the opportunity to take a fresh look at the evidence for water management on the island. The results of this study contribute substantial amounts of new information on the little known subject of Minoan water conservation and control.
Download or read book Evaluation of Check Dams for Sediment Control on Disturbed Land Surfaces written by Kevin N. Wright and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An erosion and sedimentation study was conducted and the University of Illinois at Urbana-Champaign to evaluate the suitability of using check dams as an erosion control practice on military bases. Military readiness and effectiveness is enhanced by constant training and use of their lands; this training leaves the landscape disturbed and more susceptible to erosion. Check dams are an ideal management practice to study because of their small size versus their relative impact. Five types of check dams were investigated: compost filter berm, compost sock, foam and geotextile berm, plastic dam with a compost blanket, and a riprap berm. The check dams were evaluated in two studies, one on the University of Illinois South Farms and one under a rainfall simulator. Many climactic and soil factors were measured, although the main focus was on runoff and sediment removal. The investigation revealed that all structures effectively reduced the amount of sediment lost; all except the compost sock reduced it by over 50%. Some variability was observed and all products were statistically similar with high confidence. Compost berms were the least expensive form of check dam and would likely be the best all around option for the military to use.

Download or read book Big Dams of the New Deal Era written by David P. Billington and published by University of Oklahoma Press. This book was released on 2017-04-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive dams of the American West were designed to serve multiple purposes: improving navigation, irrigating crops, storing water, controlling floods, and generating hydroelectricity. Their construction also put thousands of people to work during the Great Depression. Only later did the dams’ baneful effects on river ecologies spark public debate. Big Dams of the New Deal Era tells how major water-storage structures were erected in four western river basins. David P. Billington and Donald C. Jackson reveal how engineering science, regional and national politics, perceived public needs, and a river’s natural features intertwined to create distinctive dams within each region. In particular, the authors describe how two federal agencies, the Army Corps of Engineers and the Bureau of Reclamation, became key players in the creation of these important public works. By illuminating the mathematical analysis that supported large-scale dam construction, the authors also describe how and why engineers in the 1930s most often opted for massive gravity dams, whose design required enormous quantities of concrete or earth-rock fill for stability. Richly illustrated, Big Dams of the New Deal Era offers a compelling account of how major dams in the New Deal era restructured the landscape—both politically and physically—and why American society in the 1930s embraced them wholeheartedly.
