Analytical Solution for Long-Wave Scattering by a Circular Island Mounted on a General Shoal
(American Society of Civil Engineers, 2012)In this paper, an analytical solution is given in the form of a Taylor series for long-wave scattering by a cylindrical island mounted on a general shoal, where the water depth in the shoal region can be a real constant ... -
Beach Erosion and Recovery
(American Society of Civil Engineers, 2012)Our capability for predicting beach and dune erosion has improved in the last three decades, but the recovery of an eroded beach above the mean sea level (MSL) cannot be predicted at present. The cycle of beach erosion and ... -
Stochastic Model for Damage Accumulation in Rubble-Mound Breakwaters Based on Compatibility Conditions and the Central Limit Theorem
(American Society of Civil Engineers, 2012)Motivated by existing damage accumulation modeling difficulties, some suggestions on how to build consistent stochastic models for damage accumulation in breakwaters are given. The models avoid the selection of easy to use ... -
Seasonal to Decadal Variability of Longshore Sand Transport at the Northwest Coast of Portugal
(American Society of Civil Engineers, 2012)Longshore sediment transport (LST) is a major driver of coastal evolution. However, despite the recognition that it presents an unsteady behavior at the seasonal scale, the variability at longer term scales (interannual ... -
Probabilistic Projection of Mean Sea Level and Coastal Extremes
(American Society of Civil Engineers, 2013)Fundamental uncertainties governing sea level rise projections are associated with the rate of acceleration in global sea level rise and the local factors affecting relative sea level. Recent models and observations of ... -
Study of Scour around Submarine Pipeline with a Rubber Plate or Rigid Spoiler in Wave Conditions
(American Society of Civil Engineers, 2012)This paper presents results from laboratory experimental model studies investigating scour by waves around a pipeline attached to a flexible rubber plate or rigid spoiler. The rubber plate was placed between the submarine ... -
Experimental Study on the Scour around a Monopile in Breaking Waves
(American Society of Civil Engineers, 2012)The scour process around monopiles caused by breaking waves is studied experimentally using regular waves. The use of regular waves is conservative, which made it possible to avoid scour phenomena caused by nonbreaking ... -
Wave Overtopping at Smooth Impermeable Steep Slopes with Low Crest Freeboards
(American Society of Civil Engineers, 2012)Extensive knowledge is available on the overtopping behavior of traditional smooth impermeable sea defense structures, such as mildly sloping dikes and vertical walls, both typically featuring a high crest freeboard to ... -
How the Failure to Account for Flexibility in the Economic Analysis of Flood Risk and Coastal Management Strategies Can Result in Maladaptive Decisions
(American Society of Civil Engineers, 2012)This paper uses two alternative economic analysis approaches, net present value (NPV) and real in options (RIO), to show how the failure to incorporate uncertainty and flexibility in the economic analysis of flood risk and ... -
Fully Nonlinear Model for Water Wave Propagation from Deep to Shallow Waters
(American Society of Civil Engineers, 2012)A set of fully nonlinear Boussinessq-type equations (BTEs) with improved linear and nonlinear dispersive performance is presented. The highest order of the derivatives is three in the equations, and they use the minimum ... -
Hydrodynamic Forces on a Large Pipeline and a Small Pipeline in Piggyback Configuration under Wave Action
(American Society of Civil Engineers, 2012)Experiments on a large pipeline and a small pipeline in a piggyback configuration under regular and irregular waves are carried out. A comparison of the wave forces on the large pipeline and the small pipeline is made. The ... -
Matching Mean Sea Level Rise Projections to Local Elevation Datums
(American Society of Civil Engineers, 2013)A method is presented to consistently tie future mean sea level rise (MSLR) scenario projections to local geodetic and tidal datums. This extends the U.S. Army Corps of Engineer (USACE) guidance for incorporating the effects ... -
Waves Plus Currents Crossing at a Right Angle: Sandpit Case
(American Society of Civil Engineers, 2012)The present paper explores the possibility of exploiting sandpits at intermediate and shallow water depths by analyzing both the hydrodynamic and the morphodynamic response in the proximity of a dredged area. More precisely, ... -
Onshore Migration of Emerged Ridge and Ponded Runnel
(American Society of Civil Engineers, 2012)Ridge-runnel features can comprise large volumes of sand, and their migration can have a significant influence on the coastal sediment budget and beach recovery after a storm. Numerical modeling of ridge-runnel migration ... -
Effect of Climate Change on Performance-Based Design of Caisson Breakwaters
(American Society of Civil Engineers, 2012)This paper presents a method to incorporate the effect of climate change on the performance-based design of a caisson breakwater and its application to the East Breakwater of the Port of Hitachinaka in Honshu, Japan. The ... -
3D Numerical Modeling of Stratified Flows: Case Study of the Bosphorus Strait
(American Society of Civil Engineers, 2012)The Bosphorus Strait is a typical example of a narrow sea strait and, in general, has a two-layer flow structure. Driven by the water level difference between the Black Sea (north) and the Sea of Marmara (south), a lighter ... -
Geometrical Effects on Landslide-Generated Tsunamis
(American Society of Civil Engineers, 2012)Landslide-generated tsunami predictions are commonly based on two-dimensional (2D) wave channel or three-dimensional (3D) wave basin experiments with considerably different outcomes. It is not fully understood which idealized ... -
Optimized Predictive Two-Dimensional Hydrodynamic Model of the Gironde Estuary in France
(American Society of Civil Engineers, 2012)A two-dimensional hydrodynamic model of the macrotidal Gironde estuary (France) is developed and shown to predict the tide propagation with an accuracy of -
Resonances in an Evolving Hole in the Swash Zone
(American Society of Civil Engineers, 2012)Water oscillations observed in a 10-m-diameter, 2-m-deep hole excavated on the foreshore just above the low-tide line on an ocean beach were consistent with theory. When swashes first filled the initially circular hole on ...
