Two-Fraction Formulation of Critical Shear Stresses for Sand and Silt Mixtures
Publisher: American Society of Civil Engineers
Abstract: The bed sediments in most rivers and estuaries usually consist of mixtures of sand and mud formed by silt and clay particles. Past studies of mud have focused mainly on the cohesive properties of the mud due to the presence ...
Long-Term Equilibrium Beach Profile Based on Maximum Information Entropy Concept
Publisher: American Society of Civil Engineers
Abstract: This paper presents an application of the maximum information entropy concept to formulate an equilibrium beach profile (EBP) associated with the long-term beach evolution. The model assumes the beach profile is monotonic ...
Discussion of “New Failure Load Criterion for Large Diameter Bored Piles in Weathered Geomaterials” by Charles W. W. Ng, Terence L. Y. Yau, Jonathan H. M. Li, and Wilson H. Tang

Frequency-Size Statistics of Coastal Soft-Cliff Erosion
Publisher: American Society of Civil Engineers
Abstract: Predicting the retreat of a coastal soft cliff is a difficult and uncertain operation, which has both theoretical and practical significance. Recession of soft cliffs occurs through a combination of processes, including ...
Wave Chronology Effects on Long-Term Shoreline Erosion Predictions
Publisher: American Society of Civil Engineers
Abstract: This note presents some initial analysis of the chronology effect on critical shoreline erosion statistics using a recently developed numerical model. A 16-year hindcast wave data set from the East Coast of England was ...
Experimental and Numerical Studies on Nondestructive Evaluation of Grout Quality in Tendon Ducts Using Impact-Echo Method
Publisher: American Society of Civil Engineers
Abstract: The impact-echo method is applied to evaluate the grout quality in tendon ducts of posttensioned structures nondestructively in the present study. As the main evaluation index, the dominant frequency (DFQ) is obtained from ...
Experimental Investigation of Aerodynamic Performance of a Turbine Cascade with Trailing-Edge Injection
Publisher: American Society of Civil Engineers
Abstract: Trailing-edge mixing flows associated with coolant injection are complex and result in significant aerodynamics losses. A series of tests on a high-pressure turbine vane cascade with trailing-edge injection were conducted ...
