Book Description
Streams often present a challenge for collecting flow and sediment measurements on a year-round basis. Streams that can normally be waded become hazardous during seasonal flows, either endangering hydrographers or precluding data collection completely. A hand-operated cableway permits the accurate and safe collection of discharge and sediment data from the stream bank. This system provides a low-cost, safe alternative to cable cars or operation from bridges during high runoff. This publication describes the construction and use of a cableway system. Included are figures describing parts and dimensions, installation methods, and field operations.

Sediment Transport Data and Related Information for Selected Coarse-bed Streams and Rivers in Idaho

Category : Forests and forestry

Pages : 32
Book Description
This report and associated web site files provide sediment transport and related data for coarse-bed streams and rivers to potential users. Information on bedload and suspended sediment transport, streamflow, channel geometry, channel bed material, floodplain material, and large particle transport is provided for 33 study reaches in Idaho that represent a wide range of drainage areas, average annual streamflows, channel gradients, and substrate sizes. All the study reaches have a coarser layer of surface bed material overlaying finer subsurface material. Both bedload and suspended sediment transport increase with discharge and the relationship can be reasonably represented using a log-log model. At most sites, the suspended load makes up the majority of the total sediment load. The size of the largest bedload particle in transport and usually the median size of the bedload increase with discharge. However, the median size of the bedload is much smaller than the channel surface material and sand is the primary or a large component of the bedload material. A large proportion of the annual sediment production occurs at the higher streamflows during snowmelt. On average, discharges equal to or larger than bankfull occur 3.3 percent of the time and transport 61.5 percent of the annual bedload sediment. Discharges less than the average annual discharge, on average, occur 75.0 percent of the time and transport about 3.8 percent of the annual bedload sediment.

Book Description
Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.
