The most important depths in the designing of sluice gates are:
{{block indent |left=1.5 |text={{plainlist}}
* <math>Y_U</math>: upstream depth
* <math>Y_G</math>: opening of the sluice gate
* <math>Y_m</math>: the minimum depth of flow after the sluice gate
* <math>Y_{J1}</math>: the initial depth of the hydraulic jump
* <math>Y_{J2}</math>: the secondary depth of the hydraulic jump
* <math>Y_D</math>: downstream depth
