Design
This chapter discusses guyed structure design. Topics include loadings and design restrictions; guy clearances; guy design; guy anchorage; connections; structural design of poles and H-frames;...
Examples
This section includes several examples that illustrate many of the concepts presented in this guide. The examples and load cases have been simplified and may not represent actual design...
Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...
Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...
Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...
Potential Flow Instability Theory and Bed Forms
An extended, generalised version of two-dimensional linearised potential flow theory of fully unsteady fluid flow-sediment bed interaction is presented. In contrast to previous potential...
Impact of Sedimentation Caused by Runoff
As water is pumped into a reservoir, sedimentation caused by runoff can be an important factor in the reservoir's storage capacity. This report discusses various studies conducted...
Sediment Transport Modeling for the Glen-Colusa Irrigation District Fish Screen Modifications
The Glen-Colusa Irrigation District (GCID) pumping plant is located on an oxbow of the Sacramento River approximately 100 miles north of Sacramento (Figure 1). The existing fish screen...
Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...
Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...
Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....
Scour Study for Bridge Design on Temecula Creek
Channel-bed scour was studiedfor the proposed new Pala Road Bridge on Temecula Creek in Riverside County, California. In order to determine the general scour, sediment transport and potential...
Design of Riparian Habitat Replacement in Active Floodplains
Conventional flood control engineering techniques and approaches that have been traditionally been applied are now challenged by the public and no longer readily available as floodplain...
Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...
A Method to Study Suspended Sediment Induced Flow Characteristics Changes
Sediment-laden turbulent flows occur in nature and through man-made hydraulic structures. Our current understanding of this two-phase flow phenomenon is incomplete, and many important...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
Survival of Coliform Microorganisms in Sediments from a Treated Water Reservoir
Experiments were performed seeking the source of coliform contamination in a treated drinking water reservoir operated by the Los Angeles Department of Water and Power. In recent years...
Reservoir Sediment Management Practices of the Los Angeles County Department of Public Works
The Los Angeles County Department of Public Works (Department), which includes the Los Angeles County Flood Control District, owns and operates 15 major flood control dams. Most of these...
Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...
