Seabed classification is the important part of current coastal research because it characterizes the seabed and its habitats. Seabed characterization makes the link between the classified area and the physical, geological, chemical or biological properties of seabed. This paper addresses the possibilities of the use of airborne hyperspectral sensing with a CASI-1500 sensor to map the seabed cov...

Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern Barents Sea). Vessel Monitoring System (VMS) records and trawl marks (TM) on the seabed were used as indicators of pressure and impact of bottom trawling, respectively. Estimates ...

Video cameras are currently being employed by scientists in underwater surveys of the seabed, for various marine studies. In some instances, the duration of these surveys are quite long, which results in a mammoth of visual data that scientists have the overwhelming task of manually analyzing. It is often the case that only certain items within these recorded sequences are of scientific interes...

In this paper, the slipping friction is considered in the problem of a progressive wave of real fluids propagating over a permeable bottom.In the interface of soil and fluid, the “no-slip” condition is relaxed and a sliding friction coefficient is introduced. Thus, the slipping effect and the permeability of the bottom on the velocity near the seabed can be studied. The results indicate that th...

My long term goal is to examine how inorganic factors, such as differences in sediment character or packing, contribute to the reflectance, scattering, and fluoresence of incident light at the seabed in coastal environments. Of particular interest is the degree to which the water column light field is sensitive to inorganic changes in bottom type, and whether such changes can be described in si...

Seabed liquefaction and sediment resuspension under wave loading are key issues in marine engineering, but usually regarded as independent processes (instead of coexisting interacting processes). Here, we analyzed random wave-induced seabed its impact on using flume experiments. Results show that a nonliquefaction scenario, excess pore pressure the oscillates with fluctuations, accumulation is ...


 The present study aimed to investigate the seismic behavior of enclosed seawater walls, buried site which lies in liquefaction soil. An experimental specimen was manufactured and tested on table, a numerical also modeled ABAQUS software based outcomes. In both studies, susceptible layer around root wall considered due lean soil leakage large lateral pressure, behind caused failure sectio...

a frequency-wavenumber-domain formulation is presented in this paper for calculation of the green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. the green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. the solution is in the frequency ...
