Abstract Wave‐supported gravity flows (WSGFs) generate rates of sediment flux far exceeding other cross‐shelf transport processes, contributing disproportionately to shelf morphology and net fluxes in many regions worldwide. However, the conditions deemed necessary for formation WSGF limit them a narrow set conditions; they have been observed exclusively where seabed consists very fine‐grained typically co‐occur with nearby river flood events. Here we document occurrence event on...
Abstract We present a new mechanism for cross‐shore transport of fine sediment from the nearshore to inner shelf resulting onshore propagation river plume fronts. Onshore frontal is observed in moorings and radar images, which show that fronts penetrate through surf zone, almost waterline. During passage two‐layer counterrotating velocity field characteristic tidal straining immediately set up, generating net offshore flow beneath plume. The seaward at depth carries with it high suspended...
We present direct measurements of seafloor ripple dimensions, near-bed mean flow Reynolds stresses and turbulent sediment fluxes on a sandy inner shelf subjected to strong wave tidal current forcing. The dimensions (height, wavelength) are used evaluate the performance methodology for incorporation non-equilibrium dynamics into calculations drag exerted by bed overlying (i.e., stress) using boundary layer model wave–current interaction. is based simultaneous use existing models...

Este artigo discute como as transformações sofridas pelas ondas aquáticas ao se aproximarem de águas rasas podem auxiliar o entendimento dos principais fenômenos estudados na óptica. A partir alguns conceitos comuns a todos os ondulatórios, é possível conhecer comportamento das superfície corpos d'água conforme elas encaminham para menores profundidades, que aproximam uma praia. Tornou-se possível, dessa forma, traçar um paralelo entre luminosas e aquáticas. modelagem computacional...
O modelo de geração e propagação ondas SWAN é amplamente utilizado pela comunidade científica para obtenção estimativas do espectro em áreas costeiras, lagos estuários. cálculo da difração não era representado no tornando as simulações regiões próximas a obstáculos ou portos menos precisas. Recentemente, uma aproximação o foi implementada, porém poucos trabalhos publicados até momento abordam esta questão. Seu desempenho então investigado um terminal portuário, região onde reflexão são...

The South-Holland coast of the Netherlands undergoes influence Rhine river plume released from Rotterdam waterways. An experiment, STRAINS, was conducted to study impact fresh water on nearshore hydrodynamics and sand transport.

This thesis examines the effects of stratified tidal flow on morphodynamics Dutch inner shelf. The south portion shelf is strongly influenced by Rhine River ROFI (Region Of Freshwater Influence), which generated discharge from through Rotterdam waterways. Under conditions, three-dimensional structure currents develops a strong cross-shore shear so that bottom and surface become 180deg out phase. sheared created stratification operates in nearshore zones asymmetries imparted are expected to...
