Het fenomeen van de Bore, heb je ook op de Hooghly rivier bij Calcutta.
De schepen ankerden daar vroeger (en misschien nu nog wel) met de ankers gekruist als ik me goed herinner. Er heeft hierover, meen ik, eens artikel in de Blauwe Wimpel gestaan.
O.a deze foto's vond ik op internet:

Op Wikipedia staat o.a. dit:
Tidal bore
The tide runs rapidly on the Hugli, and produces a remarkable example of the fluvial phenomenon known as a "tidal bore." This consists of the head-wave of the advancing tide, hemmed in where the estuary narrows suddenly into the river, and often exceeds 7 feet (2.1 m) in height. It is felt as high up as Calcutta, and frequently destroys small boats. The difference from the lowest point of low-water in the dry season to the highest point of high-water in the rains is reported to be 20 feet 10 inches (6.35 m). The greatest mean rise of tide, about 16 feet (4.9 m), takes place in March, April or May - with a declining range during the rainy season to a mean of 10 feet (3.0 m), and a minimum during freshets of 3 feet 6 inches (1.07 m).
