Closure depth
Uit Kust Wiki
Definition of Closure depth:
The depth beyond which no significant longshore or cross-shore transports take place due to littoral transport processes. The closure depth can thus be defined as the depth at the seaward boundary of the littoral zone[1].
This is the common definition for Closure depth, other definitions can be discussed in the article

Definition of Closure Depth – Further notes
[2]The closure depth can be calculated using the expression[3] which is valid for "normal" sandy coastal profiles:
- d1 = 2.28HS,12h/y - 68.5 (H2s,12h/y) / (gT2s)
- where dl is the closure depth relative to mean low water-level
- HS,12h/y is the nearshore significant wave height exceeded 12 hours per year, and
- Ts is the corresponding significant wave period.
