In this study, Mazandaran province's coasts have been classified by using Relative Tide Range,  and  hydrodynamic models. For this, investigations of waves hydrodynamics, measurement of bed morphology's profiles and sediment characteristics along surfzone, and analyzing of hydrographic maps at 7 stations in east (Neka, Larim and Babolsar), middle (Mahmudabad and Kohnesara) and west pa...

Only limited information is currently available on the evolution of waves generated by wind that varies in time, and in particular on the initial stages of wind–wave growth from rest under a suddenly applied wind forcing. The emerging wind–wave field varies in time as well as in space. Detailed knowledge of wave parameter distributions under those conditions contributes to a better understandin...

Ocean wind and wave parameters can be measured by in-situ sensors such as anemometers and buoys. Since the 1980s, X-band marine radar has evolved as one of the remote sensing instruments for such purposes since its sea surface images contain considerable wind and wave information. The maturity and accuracy of X-band marine radar wind and wave measurements have already enabled relevant commercia...

Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface. While numerous methods to handle simulating oceans and other fluid phenomena have undergone rapid development during the past years in the field of comput...

INTRODUCTION In this paper, X-band COSMO-SkyMed© Synthetic Aperture Radar (SAR) data are first experimented as wind field forcing of coastal wind-wave oceanographic modeling for sea-wave numerical simulation. Experiments consist of numerical wave simulations of the SWAN model accomplished with respect to some relevant wave storms recorded in the test area during the winter season of 2010. The w...

Hanley et al. (2010, hereafter HBS) present a global climatology of wind–wave interaction based on the inverse wave age (U10 cosu)/cp, where U10 is the wind speed at a height of 10 m, cp is the phase speed of the waves at the spectral peak, and u is the angle between the wind and the direction of propagation of the dominant waves. Their paper examines the extent to which the local wave field is...

A reaction-diffusion model for the propagation of an idealized forest fire is revisited to include the effect of wind on the speed of propagation. We study the existence of one-dimensional travelling wave solutions. When the wind velocity is zero or when the wind blows from the burning region, the existence and uniqueness of the travelling wave is proved. In the case when the wind blows into th...

KUMAR, B.P. and STONE G.W., 2007. Numerical simulation of typhoon wind forcing in the Korean seas using a spectral wave model. Journal of Coastal Research, 23(2), 362–373. West Palm Beach (Florida), ISSN 0749-0208. This study investigates the application of the wave model (WAM) to simulate the generation and propagation of typhoon waves in Korean seas. The model solves the energy balance equati...
