Observations along two inner shelf transects of East-Central Florida provide information on the influence of ridge-swale bathymetry on tidal and subtidal hydrodynamics and the applicability of open channel flow theory in an area of complex bathymetry. Results from vessel-based ADCP measurements were compared to two analytical models that yield tidal and subtidal solutions. Of the two transects investigated, the northern transect, which has a relatively smooth bathymetry and a gentle bottom slope (0.002), exhibited tidal hydrodynamics that were more influenced by local acceleration than by frictional effects. Subtidal hydrodynamics at the northern transect were influenced by Coriolis (geostrophy) or by advection (Bernoulli-type dynamics). The south transect crossed a more prominent swale, with a steeper bottom slope (0.006). Frictional effects dominated the south transect as the flow maximum was located over the deepest part of the transect. Results obtained with both the tidal and subtidal analytical model solutions highlight the influence of ridge-swale bathymetry in inner shelves at those temporal scales. Analyses indicate whether open channel concepts are applicable to inner shelf dynamics.

沿佛罗里达州中东部的两个内陆架样断面的观测资料可提供有关脊流测深法对潮汐和潮汐下水动力的影响，以及明渠流理论在复杂测深法领域的适用性的信息。将基于船只的ADCP测量的结果与产生潮汐和潮汐下层溶液的两个分析模型进行比较。在所研究的两个样带中，北部样带的测深比较平稳，底面坡度平缓（0.002），其潮汐流体动力学受局部加速度的影响大于受摩擦作用的影响。北部样带的潮下水动力受到科里奥利（地球动力学）或对流（伯努利型动力）的影响。南面的横断面越过一条突出的底部，底坡越陡（0.006）。摩擦效应在南样带中占主导地位，因为最大流量位于样带的最深部分。使用潮汐和潮汐分析模型解决方案获得的结果都强调了在那些时间尺度上内陆架脊-脊深测深法的影响。分析表明明渠概念是否适用于内部货架动态。
