英文摘要: Field observations of boundary layer development within a tidally forced estuary revealed evidence of an observable viscous sublayer. Evidence is provided by several independent measures of the flow field, including hydrodynamic smoothness, an immobile bed, and characteristic velocity, constant stress, and higher-order moment structures. This investigation reports what may be the second comprehensive observation of the viscous sublayer in a marine environment, and what could be the first observation of a momentum balance that includes the viscous sublayer within a shallow estuarine environment. Hydrodynamic observations were made in a straight channel within the Great Bay Estuary of New Hampshire over a flat sandy mud with low water depth of 1.5 m at the sampling location. Beyond quantifying the role of the benthic boundary layer in nutrient dynamics, these observations are useful to provide insight into very near boundary stress estimates leading to incipient motion in estuarine and coastal environments. © 2014.
