Webb29 feb. 2024 · In the strait, the LRC was characterised by a strong asymmetry between (i) a prominent north-eastern pathway with residual currents up to 0.45 ms −1 and (ii) a southward circulation. Both upstream and downstream of the strait, we exhibited furthermore prominent cyclonic and anti-cyclonic recirculations. Webbtensive tidal flats can be ebb-dominated (e.g., FORTUNATO, OLIVEIRA, and BAPTISTA, 1999), whereas the absence of tidal flats leads invariably to flood dominance (LANZONI and SEM-INARA, 2002). The bathymetry of the tidal flats also contrib-utes to tidal asymmetry because convex profiles promote stronger ebb currents (DRONKERS, 1986 …
