CONSTRUCTIVE WAVES
Long wavelengths and low waves in height. Low energy levels and 'spill' onto the beach.
2 of 11
CONSTRUCTIVE WAVES IMPACT
Deposits material in the swash and this sediment accumulates in ridges or berms. The swash is quickly absorbed by the beach. The backwash has little power to move the sediment back towards the sea so the beach gradually develops.
3 of 11
DESTRUCTIVE WAVES
Short wavelengths and high waves in height. High energy levels cannot be easily absorbed by beach
4 of 11
DESTRUCTIVE WAVES IMPACT
Waves break from a considerable height, creating large amounts of energy which cannot be easily absorbed by the beach. These powerful waves run up the beach. The volume of water creates the opportunity for strong backwash, moving sediment back.

SWASH
Body of water pushing up a beach after a wave has broken
6 of 11
BACKWASH
The movement of water back down a beach after a wave has reached its highest point
7 of 11
TIDE
the alternative rise and fall of the level of the sea
8 of 11
TIDE FORMATION
The moon pulls water towards it, causing a swell which creates a high tide.
9 of 11
SWELL
The formation of long wavelength waves on the surface of the sea
10 of 11
STORM SURGE
High onshore winds and tides combine to give unusually high sea levels
