Subgrid tidally induced residual circulations

The Dutch Continental Shelf Model

“…In areas with strong small-scale topographic features which are of sub-grid scale, the local tidal current registrations will show a large spatial variability, even within one numerical grid cell [Abraham et al, 1987]. A quantitative assessment of this variability is required before a balanced comparison with numerical model output can be made.…”

Topographic enhancement of tidal motion in the western Barents Sea

“…If one tidal component is calculated separately, then residual field is obtained by Sea surface pattern for the M2 tide around Bear Island at the different phases of the tidal cycle.of many tidal constituents requires a different approach. In the case of many tidal components the tidally driven residual circulation is still a persistent feature, but it fluctuates with the strength of the tide over the spring neap cycle[Abraham et al, 1987]. One method is to derive a time series of 30 days and compute the average over this time span.…”

Two‐dimensional shallow flow equations for partially dry areas

“…Moreover, the wet domain is often characterized by sharp changes of water depths which, because of the nonlinearity of the flow equations, strongly affect the dynamics. Typical examples are given by bathymetry unevenness such as small-scale bed forms (ripples and/or dunes) and creeks typical of shallow estuaries and mud flat zones which actually affect the tidal propagation [Gerritsen, 1985;Abraham et al, 1987]; ground microtopography whose impact on overland flow modeling cannot be neglected [Zhang and Cundy, 1989]; and large-scale ground "irregularities" such as small channels, roads, embankments, and ground depressions, which redirect the flooding wave paths and affect the celerity of the inundation front in a flooding event [Braschi and Gallati, 1989;D541paos et al, 1994].…”
