12Rip Current Formation
Deceiving, it looks like a nice calm area
13An area of deeper water where waves dont break
14Rip Current Formation
- What is the correct sequence of rip current
formation? - Wave travels to the beach, waves break on
sandbars, water runs off beach through a channel. - B. Waves break on sandbars, wave travels to the
beach, water runs off beach through a channel. - C. Water runs off beach through a channel, wave
travels to the beach, waves break on sandbars. - D. None of the above.
15B. Waves break on sandbars, wave travels to the
beach, water runs off beach through a channel.
16Rip Current Formation
- The longer the period between waves
- a. The more energy in the the waves.
- b. The faster the waves move.
- c. The more momentum the waves carry.
- d. A and B
- e. A,B, and C
17E. a, b, and c
18Rip Current Formation
- __________ is proportional to amplitude or height
squared
19Wave energy
20Rip Current Formation
- When do rip currents become most dangerous?
- a. During high surf conditions as the wave height
and wave period increase. - b. During low surf conditions as the wave height
and wave period decrease. - c. During high surf conditions as the wave height
and wave period decrease. - d. During low surf conditions as the wave height
and wave period increase.
21 a. During high surf conditions as the wave
height and wave period increase.
22Types of Rip Currents
- This type of rip current is short in duration
(less than 10 minutes) - Enhanced by large swells with more wave energy
and volume. - Unpredictable temporary conditions and variable
locations.
23What is a Flash Rip Current?
24Types of Rip Currents
- This type of rip current develops along jetties,
piers, and groins.
25What is a Permanent rip current?
26Types of Rip Currents
- This type of rip current is dependent upon shape
of coast, bays, points, reefs or sand bars.
27What is a Fixed rip current?
28Types of Rip Currents
- This type of rip current occurs with long shore
(parallel to beach) current. - Pushes rip away from original location and
weakens it.
29What is a Traveling rip current?
30Types of Rip Currents
- A long shore current may push swimmer into
- Flash rip current
- Permanent rip current
- Fixed rip current
- All of the above
31D. All of the above
32Rip Currents Safety
- T/F Rip currents do not pull people under the
waterthey pull people away from the shore.
33True
34Rip Currents Safety
- T/F Undertow and riptides are the same as rip
currents.
35False
36Rip Currents Safety
- T/F Rip currents only occur on beaches near the
ocean.
37False, they also occur in the Great Lakes.
38Rip Currents Safety
- T/F Rip Currents can be very narrow or more
than 50 yards wide.
39True
40Rip Currents Safety
- T/F Rip currents do not affect strong
swimmers/Olympic swimmers.
41False
42Principal reasons people die in a rip current
43True
44Principal reasons people die in a rip current
- T/F Unaware of hazardous conditions
45Truealways check with the lifeguard on duty and
learn about rip currents at www.ripcurrents.noaa.g
ov before going to the beach or Great Lakes area
46Principal reasons people die in a rip current
47True
48Principle reasons people die in a rip current
49True
50Principal reasons people die in a rip current
- T/F Panic and swim directly toward shore
against the rip current, become exhausted and
drown
51True
