Transfer Vehicle Sizing for Missions to Mars
The purpose of this study is to analyze the interactions between mission and vehicle design parameters, and determine how the selection of a particular trajectory and transit time affects...
Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...
Marta North Line Midtown Station
This paper presents a case study of a cast-in-place concrete rapid transit station structure. Attention is focused on the performance of the monolithically connected, three-dimensional...
Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
Validation of the European Yield Model for Nailed Connections
Recent changes in National Design Specification for Wood Construction (NDS) connection design methods make it necessary to validate the European yield model (EYM) for nails. Test values...
Instrumentation and Testing of a Three Hinge Arch for Service Loads Increase
A three hinge arch railroad bridge was instrumented and tested to evaluate its condition and the required modification for increasing the service loads. Initially the structure was designed...
Field Tests of Railway Bridges
A research program focused on the evaluation of railway bridges has been underway for the past five years. The objectives of a research are as follows: (1) determine the loading spectra...
Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...
Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...
Galveston Bay 3D Model Study, Channel Deepening, Circulation, and Salinity Results
Galveston Bay in Texas contains the Houston Ship Channel connecting the port of Houston to the Gulf of Mexico. Due to navigational hazards, the Galveston District Corps of Engineers began...
Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Three Dimensional Modelling of Estuarine Sediment Transport
This paper describes the sediment transport module in the three-dimensional finite element model TELEMAC-3D which uses the operator splitting technique to solve the shallow water and transport...
Comparison of 2D and 3D Models for Computing Shallow Water Tides in a Friction-Dominated Tidal Embayment
The friction related overtide generating mechanisms in 2D and 3D models are compared by investigating shallow water tides in the Bight of Abaco. The 2D and 3D forms of the circulation...
Modeling of Deep Water Outfall Plumes in the East Australian Coastal Ocean
The paper reports on the modeling study of deep water outfall plumes in the east Australian coastal ocean. The primary aims of the modeling were to provide estimates of plume condition...
Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...
A Numerical Study of Hydraulic Jump and Mixing in a Stratified Channel With a Sill
An x-z plane two dimensional primitive equation model is used to study sill effects in a narrow channel. The aim is to examine the generation of internal bores/waves, hydraulic jumps and...
A New LAX-WENDROFF Algorithm to Solve the Bed Continuity Equation With Slope Effect
The numerical simulation of mobile bed evolutions of seas, estuaries and rivers requires a morphological model, including the effects of waves, currents and sediment transport, as well...
Sensitivity of Great Lakes Forecasting System Nowcasts to Meteorological Fields and Model Parameters
The Great Lakes Forecasting System is being developed by the NOAA Great Lakes Environmental Research Laboratory and Ohio State University. It uses meteorological fields as input to a numerical...
Nowcast System Development for the Straits of Florida
As part of the inaugural program for the Ocean Pollution Research Center at the University of Miami, a nowcast system is being developed for the Straits of Florida. The nowcast system...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
