Bridge Pressure Flow Scour for Clear Water Conditions
ISBN: 9781508811039 / Angielski / Miękka / 62 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Bridges are a vital component of the transportation network. Evaluating their stability and structural response after a flood event is critical to highway safety. Bridge studies are usually designed with an assumption of an open channel flow condition, but the flow regime can switch to pressure flow when the downstream edge of a bridge deck is partially or totally submerged during a large flood. Figure 1 shows a bridge undergoing partially submerged flow in Salt Creek, NE, in June 2008. Figure 2 shows a totally submerged flow in Cedar River, IA, in June 2008, which interrupted traffic on...

Junction Loss Experiments: Laboratory Report
ISBN: 9781508836353 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Storm drains generally collect storm runoff from streets, parking lots, and other structures and convey this water to a desired outfall. Access holes (or manholes), which allow staff to inspect, maintain, or repair a segment of the drainage, are usually spaced about 92 to 183 meters (m) (300 to 600 feet (ft)) apart along a given pipe and at every junction between multiple pipes. An access hole, which has at least one inlet pipe and one outlet pipe intersecting it, is usually constructed from a vertically oriented concrete pipe or box that is large enough for a person to enter by removing the...

Bottomless Culvert Scour Study: Phase II Laboratory Report
ISBN: 9781508836407 / Angielski / Miękka / 74 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Bottomless culverts are three-sided structures that use the natural channel for the bottom. These structures could be used to convey flows from one side of a highway to the other. As such, they are an environmentally attractive alternative to box, pipe, and pipe arch culvert designs. Bottomless culverts range in size from less than a meter (1.5 feet) to more than 10 meters (35 feet) in width. The failure of such a structure could have severe consequences similar to the failure of a bridge. On the other hand, since the cost of the foundation and scour countermeasures represents a significant...

Bottomless Culvert Scour Study: Phase I Laboratory Report
ISBN: 9781508836513 / Angielski / Miękka / 74 str. Termin realizacji zamówienia: ok. 5-8 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...

Field Observations and Evaluations of Streambed Scour at Bridges
ISBN: 9781508836582 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Bridge piers and highway embankments leading to a bridge often obstruct the flow of floodwaters, causing an increase in velocity and the development of vortices. The increased velocity and vortices often cause scour near the bridge foundations. The damage to and failure of bridges caused by scour are problems of national concern. This report describes the results of the second USGS national field-data collection and analysis study on scour at bridges, funded by FHWA. The database originally developed during the first national study has been enhanced and many scour measurements added,...

This report presents the summary and synthesis of the various components of the experimental study entitled "Effects of Gradation and Cohesion on Bridge Scour" conducted at Colorado State University between the dates 1991 through 1996. As a result of this effort, in excess of 250 new pier scour data was collected and a new equation was developed expressing pier scour in terms of the dimensionless excess velocity factor, flow depth, pier diameter and a correction factor for the coarse fractions present in mixtures was derived. The new method was tested with available data from previous...

Pier Scour in Clear-Water Conditions with Non-Uniform Bed Materials
ISBN: 9781508858225 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Hydraulics and scour hazards cause over half of the bridge failures in the United States and have been identified by State bridge authorities as one of the top issues in bridge design and maintenance. Current pier scour design in the United States is mainly based on the Colorado State University (CSU) equation, which is described in Hydraulic Engineering Circular No. 18 (HEC-18). A recent evaluation of bridge scour research indicated a need to change the current method because substantial advances have been made in understanding pier scour processes. The evaluation compared several methods...

Assessing Stream Channel Stability at Bridges in Physiographic Regions
ISBN: 9781508858379 / Angielski / Miękka / 162 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The goal of bridge inspections is to assess the safety of bridges on a regular basis so that any deficiencies will be identified and corrected. Given the large number of bridges over water in any State, bridge inspectors must inspect the superstructure, substructure, and waterway of each bridge in a short amount of time. A typical range of time for bridge inspections is 15 minutes to 2 hours, depending on the complexity and condition of the bridge. A more detailed inspection might ensue if a deficiency is detected. In the case of waterways and erosion, a hydraulic engineer might visit the...

Enhanced Abutment Scour Studies for Compound Channels
ISBN: 9781508858782 / Angielski / Miękka / 150 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Experimental results and analyses are given in this report on bridge abutment scour in compound channels. Experiments were conducted in a laboratory flume with a cross section consisting of a wide floodplain adjacent to a main channel. The embankment length, discharge, sediment size, and abutment shape were varied, and the resulting equilibrium scour depths were measured. Water-surface profiles, velocities, and scour-hole contours were also measured. In the report, a methodology is developed for estimating abutment scour that takes into account the redistribution of discharge in the bridge...

Nonlinear Dynamics: Mathematical Models for Rigid Bodies with a Liquid
ISBN: 9783110316551 / Angielski / Twarda / 410 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book is devoted to analytically approximate methods in the nonlinear dynamics of a rigid body with cavities (containers) partly filled by a liquid. The methods are normally based on the Bateman-Luke variational formalism combined with perturbation theory.

The Untold Story of the Lower Colorado River Authority
ISBN: 9781623493417 / Angielski / Twarda / 320 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Arguably, no other institution has transformed the heart of Texas like the Lower Colorado River Authority. Born in the Great Depression of the 1930s, LCRA built a chain of dams and brought predictability to the cycles of extreme droughts and floods that had long plagued Austin and other communities. It also brought hydroelectric power and with that, modern-day civilization to the hard-scrabble regions of Central and South Texas.
With those achievements, and the support of powerful political leaders like Lyndon Johnson, LCRA for years was touted as one of the state s major success...
