这是第二部分的调查，旨在记录的潮汐动力学的圣劳伦斯河河口（SLFE）。在第一部分中，高分辨率，二维（2D），随时间变化的流体动力学模型的SLFE的校准和验证。在这里，基于过程的（结构）验证程序，用于定量评估的模型再现在现场数据中观察到的空间和时间模式的能力。潮汐和流动的功能，被认为是令人满意的再现在潮内和每两周尺度的横向和纵向的变化。这些属性可以用来描述真实的系统动力学，包括干燥过程，潮汐传播和调制，瞬态动量平衡，提供洞察一般物理过程的SLFE和全球大型潮汐河流。
This is the second part of an investigation aimed at documenting the tidal hydrodynamics of the St. Lawrence fluvial estuary (SLFE). In Part I, the calibration and validation of a high-resolution, two-dimensional (2D), time-dependent hydrodynamic model of the SLFE was presented. Herein, the process-based (structural) validation procedure used to quantitatively assess the ability of the model to reproduce spatial and temporal patterns observed in the field data is presented. Tidal and flow features were found to be reproduced satisfactorily in terms of their lateral and longitudinal variability at both the intratidal and fortnightly scales. These properties can be used to describe the real system dynamics, including flooding–drying processes, tidal propagation and modulation, and transient momentum balance, providing insights into the general physical processes of the SLFE and of large tidal rivers globally.
