[1] Spur and groove (SAG) formations are found on the fore reefs of many coral reefs worldwide. Although these formations are primarily present in wave-dominated environments, their effect on wave-driven hydrodynamics is not well understood. A twodimensional, depth-averaged, phase-resolving nonlinear Boussinesq model (funwaveC) was used to model hydrodynamics on a simplified SAG system. The mod...

Using the full wave approach, the quasi specular contributors to the scattered fields from the large scale surface roughness as well as the Bragg-like diffusely scattered fields from the small scale surface roughness are accounted for in a unified self-consistent manner. Thus the full wave computer codes for the scattering cross sections contain ground truth data only. It has been shown how the...

To assess the role of arterial wave reflections in the mechanism of systolic hypertension and altered pulsatile arterial dynamics in patients with end-stage renal disease (ESRD), 79 ESRD patients were compared with 73 age-matched control subjects with normal renal function and similar mean blood pressure. Wave reflections were investigated from the carotid pulse contour recorded by applanation ...

We present a statistical analysis of freak waves1 measured during the 203 h of observation on sea surface elevation at a location in the coastal zone of the Baltic Sea (2.7 m depth) during June–July 2008. The dataset contains 97 freak waves occurring in both calm and stormy weather conditions. All of the freak waves are solitary waves, 63% of them having positive shape, 17.5% negative shape and...

The ocean wave distribution in a specific region of space and time is described by its sea state. Knowledge about the states ship encounters on journey can be used to assess various parameters risk wear associated with this journey. Two important characteristics state are significant height mean period. We propose joint spatial model these two quantities north Atlantic ocean. describes logarith...

In this paper, the retrieving significant wave height from X-band marine radar images based on shadow statistics is investigated, since the retrieving accuracy can not be seriously affected by environmental factors and the method has the advantage of without any external reference to calibrate. However, the accuracy of the significant wave height estimated from the radar image acquired at the n...

Prediction of the waves’ specifications that is one of the key factors effective on transformation ofcoasts, production of renewable energies and design of marine structures, has always been importante.Height of the waves is one of the most important and effective parameters of the wave. Differentfactors are effective in variation of the waves’ height. In this research, variation in waves heigh...
