Formulas to find Breaker Depth Index

Wave Height at Incipient Breaking

Wave Height at Incipient Breaking refers to the height of the wave at the point where it starts breaking, often referred to as the breaker point.

Symbol: H_b

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Wave Height at Incipient Breaking

Water Depth at Breaking

Water Depth at Breaking is the depth of water where ocean surface waves start to break as they approach the shore which depends on the wave climate and is therefore highly variable.

Symbol: d_b

Measurement: LengthUnit: m

Note: Value can be positive or negative.
