Of the three forms of hard stabilization illustrated here, which one is the groin? Nevertheless, in the CWS case, the growth of wave height stimulates nonlinearities, so the merging of bars is much stronger for waves of 1.25 m than for waves of 1 m and this leads to The step-like ridge on the beach, which is developed by waves, is termed the: The overall flow of water parallel to the coast and just below the wave breaking zone is termed: That area along the coast where waves break and water laps up and down on the beach is termed: The process of moving sediment along the beach in a zigzag fashion is known as: The net movement of sediment on the beach is: Most of the sediment drift along the coast occurs: For beach drift to occur, this has to be present: If one were to construct a concrete wall perpendicular to the coastline (a groin) what would happen to beach drift: If the beach consisted of very large boulders, beach drift would: If waves temporarily switch directions along the coast, as they do with changing storm locations, what would happen? b. b.

A longer period wave is able to sometimes wrap 180 around a barrier, when a short period wind wave will travel right past it. d. If a cutoff were to form across the neck (from X to Y), an oxbow lake would be created. However, most waves still reach the shore at a small angle, and as each one arrives, it pushes water along the shore, creating what is known as a longshore current within the surf zone (the areas where waves are breaking) (Figure 13.2.1).

When waves approach a beach at an oblique angle, resulting in a lateral movement of water along the shoreline a ___________ may develop. B. This makes the large waves of a point break ideal for surfing, while water is calmer in a bay, which is where people would launch a boat. Water flows through the pipe CCC at 4m/s4 \mathrm{~m} / \mathrm{s}4m/s. Unit 5 Quiz 2: Earth Science - GEL111_1000, When ocean waves grow so tall they topple over, they form ocean, The center of each of Earth's five major gyres is found at about ________, A ________ is characterized by two high tides and two low tides each, tidal day, with both the high and low tides having approximately the same. c.

One disadvantage of beach nourishment as compared to hard stabilization is _____. b. If you dropped a pebble in the water at one end of the beach, it could zigzag all the way along to the other end. Remember that in deep water, a waves speed depends on its wavelength, but in shallow water wave speed depends on the depth (section 10.1). The wave is incident at the Brewster's angle where the TM polarization is completely. c. Diagram A illustrates that there is more infiltration after urbanization, and therefore less water reaches the stream channel. Modelling beach morphological responses near coastal structures under oblique waves driven by sea-breezes. d. Long shore current.

Question 39 2 / 2 pts Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings ________ water to the surface. The movement of sand along the shoreline is known as beach drift. When waves approach the shore they will touch bottom at a depth equal to half of their wavelength; in other words, when the water depth equals the depth of the wave base (Figure 10.3.1). On the slide, a supersonic flow at Mach number M approaches a shock wave which is inclined at angle s . Your email address will not be published. B. transpiration Pretty simple question if you think about it. Deep ocean currents are driven by thermoheline circulation rather then prevailing winds. A. B. phyllite The energy of the breakers has both a perpendicular and a parallel component to the shoreline. Waves begin to "feel bottom" at a depth that is 1/2 of their wave length. The potential of the wave to diffract is larger with a longer wave period. When waves approach the beach at an angle, the part of the wave that reaches shallow water earliest slows down the most, allowing the part of the wave that is farther offshore to catch up. c. when winds blow on-shore 100% (1 rating) Answer: C. longshore current.

Gradient. d. The size of a flood and its recurrence interval are inversely related; the larger the flood, the shorter its recurrence interval. The The prevailing wind (the direction the wind ususally blows from) causes waves to approach the coast at an angle. The backwash (waves moving back down the beach) carries material back down the beach at right angles. It is common for waves to move toward the shoreline at an oblique angle, which causes waves to run up a beach, crossing the swash zone at an angle and flowing back perpendicular to the beach or at a similar oblique angle (Fig. Examine the figure. b.
