Constructive waves, as the name suggests, build up a beach. They are flat and low (around one metre in height) and their energy is limited. There are only a few waves per minute. The weaker backwash doesn't return all the material to the sea so the beach builds up.
The swash of a constructive wave pushes material up the beach as far as the berm - a ridge along the back of the beach. The berm marks the highest point of the spring tide.
Constructive waves form gentle beaches - an example of this can be seen at St. Cyrus.
constructive wave :)
A constructive wave is a powerful wave that surges up the beach with a powerful swash. This is the forward movement of the wave up the beach. It has a weak backwash, which is the backward movement of water down a beach when a wave has broken. Characteristics are: .swash is stronger than the backwash. .Has a low gradient. .Has low energy. .Produces gentle beach profile .Other names are: storm, surfing or plunging waves. .Typical off the SW coast of the UK.
Constructive inference.. :)
Constructive waves are waves with low energy, thus have a stronger swash then backwash. Where there are less than 8 waves breaking each minute they tend to be constructive waves. Constructive waves tend to deposit material and build up a beach.
Wave action describes the 'behaviour' of the waves. Waves can either be constructive or descrutive. Constructive waves act to build up the beach, this occures when more sediment( sand) is deposited onto the beach and less( sediment) is removed with the receding waves. Destructive waves are the opposite of constructive waves, this is when more sediment is removed than is deposited onto the beach.
Constructive interference can be a confusing concept when called interference. It is wave interference that is moving in phase with another wave. This causes the waves to for a resultant wave with a greater amplitude. Destructive interference is wave interference that is moving out of phase with another wave. These waves form a resultant wave of lower amplitude.

a constructive wave
When waves of long wave length and low height approach a gently sloping beach, the ellipse becomes horizontal. When the waves break, the swash sweeps up the beach as a sheet of water often reaching the upper beach. Most of the swash soaks into the beach which means that there is very little backwash. Waves of this type are called constructive or spilling waves.
