RISLongshore Sediment Flux in Water Column and across Surf Zone
Publisher: American Society of Civil Engineers
Abstract: Streamer sediment traps were used to measure the distribution of longshore sediment flux in the surf zone at 29 locations along the southeast coast of the United States and the Gulf coast of Florida. Measurements were ...
Spall Study in Mild Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of inertial, thermal, and rate-sensitive effects on the void growth at high strain rate in a thermal-viscoplastic solid is investigated by means of a theoretical model proposed ...
Element Analysis of Tunnel Structure with EPS Granule Layers Subjected to Blast Load
Publisher: American Society of Civil Engineers
Two‐Dimensional Branching Salt Intrusion Model
Publisher: American Society of Civil Engineers
Abstract: A two‐dimensional (in a vertical plane) branching model is developed to simulate salinity distribution in complex estuaries. The model is applied to a one‐month salinity study in the Chesapeake Bay during a period of low ...
A Yield Criterion for Porous Ductile Media at High Strain Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approximate yield criterion for porous ductile media at high strain rate is developed adopting energy principles. A new concept that the macroscopic stresses are composed of two parts, ...
Improvement of Regression Simulation in Fluvial Sediment Loads
Publisher: American Society of Civil Engineers
Abstract: In the mid-Atlantic region of the United States, sediment loads from stream runoff generally change more rapidly in the rising limb than in the falling limb of a storm hydrograph. As a result, sediment load reaches its ...
Longshore Sediment Transport Rate Measured by Short-Term Impoundment
Publisher: American Society of Civil Engineers
Abstract: The total longshore sediment transport rate in the surf zone was measured at a temporary groin installed at Indian Rocks Beach, west central Florida. Approximate mass balance between updrift accumulation and downdrift ...
Multivariable Analysis using Isoparametric Finite Elements
Publisher: American Society of Civil Engineers
Abstract: A new technique for multivariable analysis of empirical data, based on the isoparametric formulation commonly used with the finite element method, is described. Traditional two- and three-dimensional isoparametric shape ...
Assessment of Nitrogen and Phosphorus Control Trade-Offs Using a Water Quality Model with a Response Surface Method
Publisher: American Society of Civil Engineers
Abstract: Excessive nutrient loads to the Chesapeake Bay cause violations of the new dissolved oxygen water quality standard established to protect the Bay’s living resources. Reducing nitrogen and phosphorus loads is necessary to ...
Efficient Meshfree Computation with Fast Treatment of Essential Boundary Conditions for Industrial Applications
Publisher: American Society of Civil Engineers
Abstract: This paper presents a fast treatment of essential boundary conditions in three-dimensional (3D) meshfree computation for computational efficiency. Due to the loss of Kronecker delta properties in the meshfree shape functions, ...
