Matching Mean Sea Level Rise Projections to Local Elevation Datums

Reinhard E. Flick, Kevin Knuuti, and Stephen K. Gill
A method is presented to consistently tie future mean sea level rise (MSLR) scenario projections to local geodetic and tidal datums. This extends U.S. Army Corps of Engineer (USACE) guidance for incorporating effects of future MSLR into coastal projects. While USACE relies on the National Oceanic an ...

Numerical Modeling of Breaking Waves and Cross-Shore Currents on Barred Beaches

Mustafa Kemal Cambazoglu and Kevin A. Haas
A process-based numerical model has been used to study nearshore hydrodynamics on barred beaches. A laboratory experiment with an offshore bar migration case followed by an onshore bar migration is simulated. A new mechanism is incorporated in the model accounting for the breaking-wave persistence i ... [J.

Scour at Vertical Piles in Sand-Clay Mixtures under Waves

Subhasish Dey, Anders Helkjaer, B. Mutlu Sumer, and Jorgen Fredsoe
Marine sediments often contain sand-clay mixtures in widely varying proportions. This study presents the results of equilibrium scour and time variation of scour depths at circular piles embedded vertically in clay alone and sand-clay mixed beds under waves. Experiments were conducted in a wave flum ... [J. Waterway, Port, Coastal, Ocean Eng. doi:10.1061/(ASCE)WW.1943-5460.0000095] published Fri Dec 16, 2011.

Long-Wave Scattering by a Vertical Cylinder with Idealized Scour Pit

Xiaojing Niu and Xiping Yu
The combined diffraction and refraction of long waves around a vertical cylinder with scour pit is studied analytically on the basis of a newly derived analytic solution of the mild-slope wave equation. The geometry of the scour pit around the cylinder is idealized to be axisymmetrical, and a simple ... [J.

Flood Simulation in an Urban Catchment of Navi Mumbai City with Detention Pond and Tidal Effects Using FEM, GIS, and Remote Sensing

S. S. Shahapure, T. I. Eldho, and E. P. Rao
Urban flooding caused by heavy rainfall and high tides is a major problem in many coastal cities. For example, major cities in India have witnessed loss of life and property, disruption to transport and power, and incidences of epidemic during monsoon, most notable among them Mumbai in 2005, Surat i ...

Experimental Investigation of Cylindrical Floating Breakwater Performance with Various Mooring Configurations

Y. Ozeren, D. G. Wren, M. Altinakar, and P. A. Work
Floating breakwaters are typically used to protect small marinas or for shoreline erosion control on limited-fetch water bodies in which wavelengths are relatively short, such as lakes, reservoirs, and bays. In spite of the large amount of literature on floating breakwaters, there is still a lack of ... [J.

Diffraction of Water Waves by a Semisubmerged Structure in a Channel

Wojciech Sulisz
A theoretical approach is applied to describe the diffraction of water waves by a structure in a channel of arbitrary configuration. The solution was achieved by applying the three-dimensional (3D) boundary element method and is valid for a structure of arbitrary shape. The derived model was applied ... [J.

Onshore Migration of Emerged Ridge and Ponded Runnel

Jens Figlus, Nobuhisa Kobayashi, and Christine Gralher
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 is challenging partly because of the strong interactions between the hydrodynami ...
