Uncertainty Quantification of Transient Unsaturated Seepage through Embankment Dams
Publisher: American Society of Civil Engineers
Bridge Scour Risk Assessment and Countermeasure Design
Publisher: American Society of Civil Engineers
Abstract: Statistical surveys conducted on investigation of reasons of bridge failures implied that the majority of bridges have failed because of excessive scouring at infrastructural elements. A bridge crossing an alluvial river ...
Hydrological Aspects of Bridge Design: Case Study
Publisher: American Society of Civil Engineers
Abstract: Many bridges are destroyed or fail completely during severe floods. If the cause of the damage is not a structural deficiency, it may be excessive local scour around bridge piers and/or abutments. Although the mechanics ...
Probabilistic Evaluation of the Effects of Uncertainty in Transient Seepage Parameters
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effect of uncertainty in the hydraulic conductivity and van Genuchten fitting parameters used for unsaturated flow modeling of transient seepage through embankment dams. Random variables of the ...
Renovation of a Safety-Inspection Methodology for River Bridges
Publisher: American Society of Civil Engineers
Abstract: River bridges and related infrastructural elements need to be monitored and inspected periodically for deterioration and loss of function due to aging, adverse hydraulic conditions, and chemical attacks. Necessary protective ...
Evaluation Study on the Instrumentation System of Cindere Dam
Publisher: American Society of Civil Engineers
Abstract: The first hardfill dam in Turkey, Cindere Dam, has recently been constructed and a number of instruments have been installed. The aim of this study is to review the capability of the current instrumentation system and to ...
Study of Time‐Depenbent Local Scour around Bridge Piers
Publisher: American Society of Civil Engineers
Abstract: Estimation of maximum possible scour depth around bridge piers is an important step in the design of bridge pier foundations. Under known hydrological characteristics such as peak discharge and time‐to‐peak value of design ...
Determination of Minimum Intermediary Hold Durations in Multistage First-Filling Schedule of Earth-Fill Dam Reservoirs
Publisher: American Society of Civil Engineers
Abstract: Earth-fill dams should be monitored during the first filling of the reservoir to avoid several potential risks. Following the completion of dam construction, the primary safety check is monitoring the dam behavior during ...
Stability of Bridge Piers Subjected to a Probable Flood Event Followed by a Probable Seismic Event
Publisher: American Society of Civil Engineers
Abstract: Scour-induced reduction in bridge stability can develop vulnerabilities during a probable seismic event. This problem has been typically addressed by researchers as if these two extreme events have no joint probability of ...
Rubble‐Mound Breakwaters With S‐Shape Design
Publisher: American Society of Civil Engineers
Abstract: When a single‐slope, rubble‐mound breakwater is subjected to waves that dislocate the stones but do not cause any overtopping, the damaged section may become stabilized at a certain level of wave attack, generating the “
