The order of magnitude, about 0.05 m.s is similar in both cases. The
highest velocity values can be obscrved near the mouth of the estuary.
Although a two-layered residuai circulation pattern appears in both
cases, the presence of the dock induces a gyre in the middle part of the
estuary. The differences between both patterns gi\’e rise to a different
residence time in the harbour area, calculated at sections I and II (fîg. la,
lb). A considerable increase, about 35%, in residence time can be observed after the building of the dock.
