Bank Configurations

Four different types of bank configurations are tested. In every case one bank is a straight quay wall (=wall of the towing tank). The bank on the other side changes.

Bank I

Bank I is a straight quay wall. This is common at the berthing docks in most harbours.

Bank II

Bank II is a sloped bank. The slope is 1/5. This slope is common in the inner harbour of Zeebrugge.

Bank III

Bank III is a sloped bank (slope 1/5 as Bank II) with a submerged horizontal plate. This is an analogue configuration as at Sternenschiereiland in the harbour of Zeebrugge.

Bank IV

This bank is analogue as Bank III. To investigate the influence of a bigger Sternenschiereiland on the bank effect, the slope is the same (1/5) but the horizontal plate is less deep. Two variations on this configuration have been tested. The width of the horizontal plate has been halved (IV3) and quartered (IV4).

Bank V

Bank V is a surface piercing bank with a slope of 1/8. This is a common slope on the river Scheldt.

Bank VI

Bank VI is a bank with the same slope as Bank V (1/8) and with the same horizontal plate as Bank IV. This is analogue as in "Bocht van Bath" on the river Scheldt.

Bank VII

Bank VII has a slope of 1/3. This is the bank as can be found on some canals (Gent-Terneuzen).

Bank VIII

Bank VIII is a vertical wall but the distance between the bank and the centre line of the towing tank changes harmonically.
