摘要

Abstract > A multibeach Lagrangian data set was used to determine bathymetric controls on flow variability within the surfzone. Seven microtidal flow regimes were examined, six containing rip channels, under moderate shore normal waves. Three selected zones exemplified varying bathymetric control: (i) a alongshore uniform zone; (ii) a shallow rip channel at an oblique angle to shore normal; and (iii) a deep, shore‐normal rip channel. Bathymetric variables included alongshore nonuniformity ( type="mathematics"> Φ ) and channel angle relative to shore normal ( type="mathematics"> α ). Low‐frequency flow (0.01?Hz) was described by velocity ( type="mathematics"> U ), velocity standard deviation ( type="mathematics"> σ <sub> U </sub> ), angular deviation ( type="mathematics"> σ <sub> θ </sub> ), and bias in direction of eddy rotation ( type="mathematics"> ζ <sub>bias</sub> ). Observations of the exemplar zones indicated the following: (i) near‐zero mean flow with transient eddies within the alongshore uniform zone; (ii) low mean flow with high type="mathematics"> ζ <sub>bias</sub> within the oblique channel; and (iii) strong mean flow with low type="mathematics"> ζ <sub>bias</sub> in the deep channel. Bathymetry and flow variables were spatially averaged and linearly correlated, scaling for wav </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译:</span><Abstract Type =“Main”XML:Lang =“en”> <标题类型=“main”>抽象</ title> >多展拉格朗日数据集用于确定Surfzone内的流动变异性的碱基控制。检查七个含有RIP通道的六个六个脉冲频道,在中等岸上正常波。三个选定的区域示例了不同的碱基对照:(i)沿岸均匀区域; (ii)以斜角到岸正常的浅裂沟道; (iii)深,岸上正常的RIP通道。散系变量包括沿岸不均匀性(类型=“数学”> φ</ i> </ span>)和相对于岸正常的频道角度(<跨度类型=“数学”> α</ i > </ span>)。通过速度描述了低频流量(0.01?Hz)(<跨度类型=“数学”> U </ i> </ span>),速度标准偏差(<跨度类型=“数学”> <i >σ</ i> <sub> </ sum> </ sub> </ sup>)角偏差( type =“数学”> σ</ i> <sub> < i>θ</ i> </ sup>),偏置涡流方向(<跨度类型=“数学”> ζ</ i> <sub>偏置</ sub> < / span>)。示例区域的观察表明以下:(i)与沿岸均匀区域内的瞬态漩涡接近零平均流动; (ii)具有高<跨度型=“数学”> ζ</ i> <sub>偏置频道中的ζ的偏置; (iii)具有低类型=“数学”> ζ</ su> <sub>偏置</ sub> </ span>的强平均流量。沐浴和流量变量在空间平均和线性相关,为WAV缩放 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-34664/'>《Journal of geophysical research.
