Question

What is a constructive wave

Answer 1

constructive waves are the waves that build up the beaches. They have a large 'swash', which means they can carry deposits of sand and other materials far up the beach

Answer 2

Constructive wave is a wave that leads to the build-up of a beach, owing to the swash of the wave being more effective in moving material than the backwash. Usually, constructive waves are associated with low-energy conditions and a gentle offshore gradient.
