BEACH CHANGES IN ODAIBA COASTAL PARK AND SHORE PROTECTION

Morphological Shoreline Changes along the Lake Clark National Park - Cook Inlet Coast , 1992 - 2004 . Joel Cusick

Shoreline change was identified as a vital sign for the Southwest Alaska Monitoring Network because land loss or gain at the marine edge has important ecological and jurisdictional implications to resource managers of coastal National Parks. To evaluate the type of shoreline changes occurring along the 82 km coastline of Lake Clark National Park and Preserve, 7 of 10 cross-shore beach profiles ...

An Investigation on Beach Profile Changes in Front of Seawalls

Although there exist advanced models which predict beach profile for natural beaches, the behavior of the beaches in front of seawalls still suffers from the lack of appropriate theoretical models and sufficient measured data. In this paper, following the results obtained from the measurements, a beach profile evolution model is developed, using the measured probability distribution of the nea...

Shore protection by oblique seabed bars

Shore protection by small seabed bars was once considered possible because seafloor undulations strongly reflect surface waves of twice the wavelength by the so-called Bragg resonance mechanism. The idea, however, proved “unreliable” when Yu & Mei (J. Fluid Mech., vol. 404, 2000, pp. 251-268) showed that a patch of longshore seabed bars adjacent to a reflective shore could result in larger wave...

An integrated coastal modeling system for analyzing beach processes and beach restoration projects, SMC

A user-friendly system called coastal modeling system (SMC) has been developed by the Spanish Ministry of Environment and the University of Cantabria. The system includes several numerical models specifically developed for the application of the methodology proposed in the Spanish Beach Nourishment and Protection Manual. According to this methodology, the SMC is structured into five-modules: (1...
