We thank the anonymous referee #1 for the positive and constructive remarks. Just like the referee, we struggled to improve and simplify the presentation of the technical results. In section 2 we tried to illustrate in a simple way the role of coherence by considering the (weak) pseudo-maximal signals. Then, to justify the use of the wavelet transform, we showed how the coherence of phase infor...

One-way recursive wavefield extrapolation and migration has many advantages over other wavefield extrapolation methods. The method can handle complex models and is robust. However, the extrapolation of turning waves is one important omission of one-way wavefield extrapolation In this paper a new hybrid approach for the imaging of steep salt flanks is presented: CFP redatuming is used to redatum...

The role of various long-wave approximations in the description wave field and bottom pressure caused by surface waves, their relation to evolution equations are being considered. In framework linear theory, these tested on well-known exact solution for spectral amplitudes variations. famous Whitham, Korteweg–de Vries (KdV) Benjamin–Bona–Mahony (BBM) have been used as evolutionary equations. It...

Parasitic ripple generation on short gravity waves (5 cm to 10 cm wavelengths) is examined using fully-nonlinear computations and laboratory experiments. Time-marching simulations show sensitivity of the ripple steepness to initial conditions, in particular to the crest asymmetry. This unique unsteady e ect enhances ripple generation at moderate wave steepness, e.g. ka between 0.15 and 0.20, a ...

This paper investigates the wave transmission through artificial reefs utilised as low-crested breakwaters to mitigate coastal erosion and reduce energy. The study utilises DualSPHysics smoothed particle hydrodynamics (SPH) solver evaluate effectiveness of such structures. Wave coefficients were computed for various reef configurations conditions. Results indicate that shifted configuration pro...

circular- crested weirs are employed for flow measurement among their other wide applications in hydraulic engineering. they can also be used to control water level in farm ponds and reservoirs. advantages of the circular crested weirs as compared to other weirs include the stable overflow pattern, the simplicity of design and their associated lower costs. in this study, the curvilinear flow pa...

This paper presents the effects of two-dimensional bathymetry on evolution skewness and kurtosis surface elevation velocity field in long-crested irregular waves propagating over a circular shoal submerged bar with semicircular step. For shoal, we show that has local maximum top shoal. We find horizontal similar behaviour to elevation, but two maxima at different locations lee side step, which ...

We examine the utility of the action potential (AP) duration (APD) restitution curve slope in predicting the onset of electrical alternans when electrotonic and memory effects are considered. We develop and use two ionic cell models without memory that have the same restitution curve with slope >1 but different AP shapes and, therefore, different electrotonic effects. We also study a third cell...
