Methodology for Combining Coastal Design-Flood Levels and Sea-Level Rise Projections
(American Society of Civil Engineers, 2013)Design-flood levels with associated exceedance probabilities are usually determined for coastal flood protection projects. Rising sea level introduces another design feature that needs to be combined with the design-flood ... -
Exact Solution to the Modified Mild-Slope Equation for Wave Scattering by a Cylinder with an Idealized Scour Pit
(American Society of Civil Engineers, 2013)In this paper, wave scattering by a vertical cylinder with a scour pit governed by the modified mild-slope equation (MMSE) is studied analytically. The scour pit around the cylinder is assumed to be axi-symmetric and ... -
Experimental Study of Local Scour around Twin Piles in Oscillatory Flows
(American Society of Civil Engineers, 2013)Laboratory experiments have been carried out to investigate the scour around single piles and twin-pile groups subject to oscillatory flows. The Keulegan-Carpenter number, which is proportional to the ratio between the ... -
Sea-Level Rise Effects on Storm Surge and Nearshore Waves on the Texas Coast: Influence of Landscape and Storm Characteristics
(American Society of Civil Engineers, 2013)Sea-level rise (SLR) estimates vary broadly, but most estimates predict significant increases in sea levels within the next century. Through the use of validated, coupled wave and hydrodynamic models, this study investigates ... -
Simple Methodology for Deriving Continuous Shorelines from Imagery: Application to Rivers
(American Society of Civil Engineers, 2013)A methodology is developed to extract and process shoreline data, the interface between land and water, identified from imagery. Initially, image pixels containing water (water points) and pixel locations of the land/water ... -
Quay Length Optimization Using a Stochastic Knapsack Model
(American Society of Civil Engineers, 2013)Vessels arriving at a port wait for an available berth at the quay to load/unload. The ability to provide a berthing space for a vessel without delay is a major managerial concern. Thus, there is an optimal resource-allocation ... -
Lower Columbia River Sand Supply and Removal: Estimates of Two Sand Budget Components
(American Society of Civil Engineers, 2013)Long-term changes in the sand balance of a river-estuary system can strongly affect navigation and ecosystems. Here, we examine two sand budget components in the lower Columbia tidal river, fluvial supply and human removal. ... -
Investigation of Single and Multiple Solitary Waves Using Superresolution PIV
(American Society of Civil Engineers, 2013)Measurements of the characteristics of a solitary wave propagating alone or against a current were performed using superresolution particle image velocimetry (PIV). The velocity field was obtained when the solitary wave ... -
Surge Generation Mechanisms in the Lower Mississippi River and Discharge Dependency
(American Society of Civil Engineers, 2013)The Lower Mississippi River protrudes into the Gulf of Mexico, and manmade levees line only the west bank for 55 km of the Lower Plaquemines section. Historically, sustained easterly winds from hurricanes have directed ... -
Influence of Settling Behavior of Soil Particles on the Consolidation Properties of Dredged Clay Sediment
(American Society of Civil Engineers, 2013)Placement of dredged spoils in a slurry form and allowing self-weight consolidation is common in land reclamation works carried out adjacent to water bodies. The influence of the settling behavior of soil particles in ... -
Comparison of Calculation Methods of Cumulative Damage to Breakwater Armor Layer
(American Society of Civil Engineers, 2013)In the probabilistic design of a breakwater armor layer, it is often necessary to calculate the damage accumulated over the breakwater's life cycle. In this paper, a comparison is made between existing methods to calculate ... -
Boat-Wake Statistics at Jensen Beach, Florida
(American Society of Civil Engineers, 2013)Ship/boat wakes are identified in pressure and flow velocity records as chirp signals, which are also known as sweep signals in sonar and radar applications. A chirp is a signal in which the frequency increases or decreases ... -
Deformation of Reef Breakwaters and Wave Transmission
(American Society of Civil Engineers, 2013)The risk-based design of a reef breakwater requires the prediction of the temporal variations of the damage and wave transmission coefficient during storms. The cross-shore numerical model is extended to the landward zone ... -
Rapid Assessment of Wave and Surge Risk during Landfalling Hurricanes: Probabilistic Approach
(American Society of Civil Engineers, 2013)A probabilistic framework is presented for evaluation of hurricane wave and surge risk with particular emphasis on real-time automated estimation for hurricanes approaching landfall. This framework has two fundamental ... -
Influence of Three Levee-Strengthening Systems on Overtopping Hydraulic Parameters and Hydraulic Equivalency Analysis between Steady and Intermittent Overtopping
(American Society of Civil Engineers, 2013)Different types of strengthening systems were introduced to protect the crest and land-side slope of the levees against surge overflow and wave overtopping after Hurricane Katrina. Three levee-strengthening systems, ... -
Validation of a Risk-Based Numerical Model for Predicting Deep-Draft Underkeel Clearance
(American Society of Civil Engineers, 2013)The channel analysis and design evaluation tool ( -
Vortex-Induced Dynamic Response Analysis for the Submerged Floating Tunnel System under the Effect of Currents
(American Society of Civil Engineers, 2013)This paper describes an investigation of vortex-induced vibrations in a submerged floating tunnel (SFT) system. A theoretical model for coupled tube-cable vibration was developed to evaluate the SFT structural dynamic ... -
Sea-Level Rise Impact on a Salt Marsh System of the Lower St. Johns River
(American Society of Civil Engineers, 2013)The impact of sea-level rise on salt marsh sustainability is examined for the lower St. Johns River and associated salt marsh ( -
Stability of Wide-Graded Rubble Mounds
(American Society of Civil Engineers, 2013)The reshaping of temporary rubble mounds such as breakwater cores or reclamation bunds is a concern for maritime contractors. Literature formulas for the prediction of such behavior provide little insight in the influence ... -
