[[de:Funktionelle Abhängigkeiten]]

The parameters for the water level and current variations caused by a moving ship are a function of:
* ship velocity '''vS''' and the passing distance '''L'''
* ship dimensions (length '''l''', width '''b''', draught '''t''', submerged midship cross-section '''AS''')
* total hydrodynamic resistance of the ship (ship form) in the canal '''RT,K'''
* waterway conditions (water level '''B''' and bed width '''BS''', water depth '''d''', cross-section and area '''A''', bank profile and slope '''1 : m''')
* current conditions in the waterway
* other influences such as waterway bend, type of propulsion, water density.
 
The ''essential'' parameters for the ship induced loading for fairways have been shown to be:
* the ship velocity ('''vS''')
* the passing distance ('''L''') to the bank edge which defines the hydraulic partial cross-section ('''AT''')
* the water depth to draught ratio ('''d/t'''), and the cross-section ratio '''AT / 0,5 AS'''.

To illustrate more simply the physical processes occurring when a ship is moving in a waterway of varying non-uniform cross-section, one may think of the waterway cross-section as being divided into two parts '''AT1''' and '''AT2''', through each of which half of the ship's displacement passes. Thus each bank experiences a qualitatively different ship induced loading as is determined by the partial cross-section ratios '''AT1 / 0,5 AS''' and '''AT2 / 0,5 AS'''.
