Winds Flashcards
1
Q
Wave action
A
The source for coastal erosion and sediment transport
2
Q
How is wave energy generated?
A
It is generated by the frictional drag of winds moving across the ocean surface
3
Q
What are onshore winds?
A
Winds blowing from the sea to land
4
Q
Are onshore winds effective at driving winds to the coast?
A
Yes
5
Q
The impact of winds blowing at an oblique angle
A
Coastal waves will approach obliquely causing LSD
6
Q
What happens if the wind speed and fetch increases?
A
It generates larger waves with more energy
7
Q
Equation for wave height and units
A
Wave height (m)= 0.36 × square rooted fetch (km)
