REVETMENT
This concrete lining
is to protect the
banks against erosion.
Note the arch in the
diagram is to celebrate
The Queen opening the

ARTIFICIAL HARBOURS
Artificial Harbours are created through Engineering
processes such as
● Dredging
● Introduction of Coastal Structures (e.g Breakwater)
Artificial Harbours provide a safe haven for Marine Vessels

VAN der MEER FORMULAE
SURGING WAVES CONDITION FORMULA
(HS / Dn 50 ) = 1.0P-0.13 ( S / N )0.2 Cot 0 EmP
P = Notional Permeability Factor
S = Damage Level
N = Number of Waves ( Storm Duration)
Dn50= Normal Stone Diameter
Em= Iribarren Number ( Surf Similarity Parameter )
= Relative Mass Density
HS= Significant Wave Height

CHANNEL WIDTH
The Nominal Width of the Channel is influenced by
numerous factors , e.g
● Ship Maneuverability
● Ship Proportions
● Sea Lanes
● Channel Curvature
● Human Factors
● Currents
● Traffic Volume
● Speed
