Question 3: Shoreline Processes - Waves and Coastlines

The ocean surface is influenced by three types of motion (waves, tides, and surface currents). Shorelines dominated by wave action compromise approximately of the global coastlines. Tidal actions dominate , and surface ocean currents (example Gulf Stream) dominate only of global coastlines. The following questions deal with coastlines dominated by wave action.

Remember:

Wave base wavelength

Shallow water waves occur when the circular motion moving waves forward is interrupted by the ocean floor and the wave slows down and builds in height as a transitional wave…

The ratio of wave height to wavelength is a measurement of the steepness of a wave. deep water wave will break when it reaches a steepness value of .
note: meter

Answer the following question in reference to the information provided.

3-1: For a fair-weather wave, with a deep water wavelength of 3 meters, the wave becomes a transitional wave at an approximate water depth of
50 cm or 0.5 m
2.75 meters
1.5 meters
8.00 meters

1. The given deep water wavelength is $$ \lambda = 3 $$ meters.

2. The wave base is defined as half of the wavelength, so
   $$
   \text{Wave base} = \frac{1}{2} \lambda = \frac{1}{2} \times 3 = 1.5 \text{ meters}.
   $$

3. Thus, the fair-weather wave becomes transitional when the water depth is approximately $$ 1.5 $$ meters.

Final Answer: $$ \boxed{1.5 \text{ meters}} $$.
The wave becomes transitional at approximately 1.5 meters of water depth.
