Bottomless Culvert Scour Study: Phase I Laboratory Report
ISBN: 9781508836513 / Angielski / Miękka / 2015 / 74 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Bottomless (or three-sided) culverts use the natural channel bed and are environmentally attractive alternatives to traditional closed culverts. Moreover, they are considered by many highway agencies to be economical alternatives for replacing short bridges. They are typically placed on spread footings, and the issue of scour and the depth of footing must be addressed. The scour problem is analogous to abutment and contraction scour in a bridge opening and can be treated in much the same manner. Since abutment scour estimates at bridge openings are often quite large, a scour protection task...

ISBN: 9781508666509 / Angielski / Miękka / 2015 / 648 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The Federal Highway Administration document "Highways in the River Environment - Hydraulic and Environmental Design Considerations" was first published in 1975, was revised in 1990, and is now issued as Hydraulic Design Series 6, "River Engineering for Highway Encroachments." This document has proven to be a singularly authoritative document for the design of highway associated hydraulic structures in moveable boundary waterways. This revised document incorporates many technical advances that have been made in this discipline since 1990. In addition, Hydraulic Engineering Circulars (HEC) 18,...

Durability Analysis of Aluminized Type 2 Corrugated Metal Pipe
ISBN: 9781508836681 / Angielski / Miękka / 2015 / 108 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Durability of Culverts and Special Coatings is intended to provide up-to-date storm drain and culvert material selection methods and techniques to assist the highway engineer in designing culverts. While the program was to consider a variety of materials, the predominant focus was on Aluminized Type 2 corrugated steel pipe (CSP) and its performance versus galvanized CSP. This report is divided into two main sections-field investigation and literature review. The field investigation presents the results of a field evaluation of 32 pipes and their performance relative to that reported in...

Hydraulic Design of Energy Dissipators for Culverts and Channels: Third Edition
ISBN: 9781508680642 / Angielski / Miękka / 2015 / 290 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The purpose of this publication is to provide design information for analyzing and mitigating energy dissipation problems at culvert outlets and in open channels. It provides general information on the overall design process, erosion hazards, and culvert outlet velocity and velocity modification. These provide a background and framework for anticipating dissipation problems. In addition to describing the overall design process, design examples to compare selected energy dissipators are provided. Also provided are assessment tools for considering flow transitions, scour, and hydraulic jumps.

Freeway Geometric Design for Active Traffic Management in Europe
ISBN: 9781480263864 / Angielski / Miękka / 2012 / 90 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Continued growth in travel on congested urban freeway corridors exceeds the ability of agencies to provide sufficient solutions and alternatives based on traditional roadway expansion and improvement projects. Several countries are implementing managed motorway concepts to improve motorway capacity without acquiring more land and building large-scale infrastructure projects. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and National Cooperative Highway Research Program sponsored a scanning study of England, Germany, the Netherlands,...

Effects of Inlet Geometry on Hydraulic Performance of Box Culverts
ISBN: 9781508858591 / Angielski / Miękka / 2015 / 164 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The South Dakota Department of Transportation (SDDOT) and the Federal Highway Administration (FHWA) collaborated on a research study to determine the effects of a number of inlet geometry choices on culvert hydraulic efficiency. This study is a response to the large number of culverts that are installed in the United States and the fact that most of the current guidelines on culvert hydraulics are based on research completed more than 20 years ago. The objectives of this study were to: Determine optimum edge conditions for wingwalls; Determine the effects of inlet geometry on flow capacity of...

Stream Stability at Highway Structures: Fourth Edition
ISBN: 9781508680826 / Angielski / Miękka / 2015 / 330 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Approximately 500,000 bridges in the National Bridge Inventory (NBI) are built over streams. A large proportion of these bridges span alluvial streams that are continually adjusting their beds and banks. Many, especially those on more active streams, will experience problems with aggradation, degradation, bank erosion, and lateral channel shift during their useful life. The purpose of this document is to provide guidelines for identifying stream instability problems at highway stream crossings. Techniques for stream channel classification and reconnaissance, as well as rapid assessment...

Currently, a well-defined and validated set of metrics to use in monitoring work zone performance do not exist. This pilot test was conducted to assist state DOTs in identifying what work zone performance measures can and should be targeted, what data they will need to collect to compute those measures, and what methods exist to obtain that data. Work zone activity and traffic data from five work zone projects were gathered and analyzed. Multiple data sources and collection methods were examined and utilized to the extent available at each project. These sources were field crew personnel...
