RISDelineating Infrastructure Failure Interdependencies and Associated Stakeholders through News Mining: The Case of Hong Kong’s Water Pipe Bursts
Publisher: ASCE
Abstract: The failure of one infrastructure system could trigger cascading impacts on other interdependent infrastructures. In order to improve the management of diverse infrastructure systems, decision makers should be mindful of ...
Method for Estimating Clear-Water Local Scour Rate at Complex Piers
Publisher: ASCE
Abstract: When estimating design local scour depths at structures where the design flows have short durations, equilibrium scour depths can be too conservative. Attempts to develop methods to accurately estimate scour rates and times ...
Flow Redistribution at Bridge Contractions in Compound Channel for Extreme Hydrological Events and Implications for Sediment Scour
Publisher: ASCE
Abstract: This study investigates the flood flow characteristics in a compound channel subject to both lateral contraction (caused by bridge abutment/embankment) and vertical contraction (caused by bridge deck submergence) at bridge ...
Effects of Streamwise Abutment Length on Scour at Riprap Apron-Protected Setback Abutments in Compound Channels
Publisher: ASCE
Abstract: Scour at bridge abutments usually consists of local and contraction scour that correlate because of the flow field that develops both scours. Flume experiments were conducted using simulated compound channels to investigate ...
Delineating Flood-Induced Sediment Scour in Bridge-Contracted Channels: Processes, Patterns, and Scour Depth under Various Scour Regimes
Publisher: American Society of Civil Engineers
Abstract: Flooding water in extreme hydrometeorological events may be significantly contracted by bridge abutments and superstructures, leading to severe sediment scour and threatening structure stability. A series of large-scale ...
Revelation and Enhancement for Pedestrian Evacuation at Metro Station: Metamodeling-Based Simulation Optimization Approach
Publisher: American Society of Civil Engineers
Abstract: As urban populations continue to grow rapidly, the demand for efficient public transportation systems has increased. Consequently, metro stations have become indispensable components of urban infrastructure. Despite their ...
Hydrodynamic Uplift Forces on Submerged Bridge Decks during Bedform Migration
Publisher: ASCE
Abstract: Hydrodynamic forces, especially uplift forces, during a flood event are critical to the stability of bridge superstructures. This study focuses on the interaction between the migrating dunes, the scour depth beneath the ...
Temporal Evolution of Clear-Water Local Scour at Aligned and Skewed Complex Bridge Piers
Publisher: ASCE
Abstract: Scour at bridge piers is time-dependent. In this paper, temporal evolution of clear-water scour at complex bridge piers is studied experimentally. The pier model has a typical form comprising three components, namely a ...
Live-Bed Scour at Wide and Long-Skewed Bridge Piers in Comparatively Shallow Water
Publisher: American Society of Civil Engineers
Abstract: An investigation of the characteristics of live-bed scour at circular and skewed rectangular (slab) piers in comparatively shallow flows is presented. The 110 experiments were undertaken in a 2.4-m flume using two circular ...
