Rip current statistics l.jpg

Rip Current Statistics

T/F - Around 100 people die in rip currents each year U.S.


Slide3 l.jpg

True


Rip current statistics4 l.jpg

Rip Current Statistics

T/F -Most victims are in the ocean waters of:

a. Florida

b. California

c. Carolinas

d. All of the above


D all of the above l.jpg

D. All of the above


Rip current statistics6 l.jpg

Rip Current Statistics

T/F - Rip currents also kill people in the Great Lakes.


Slide7 l.jpg

True


Rip currents statistics l.jpg

Rip Currents Statistics

T/ F The chance of drowning at a beach protected by lifeguards affiliated with USLA is 1 in 18 million.

True


Rip currents l.jpg

Rip Currents

T/F More people die in rip currents than the deaths from hurricanes, lightning, flooding, and tornadoes.

True


Rip current formation l.jpg

Rip Current Formation

Deceiving, it looks like a nice calm area:


An area of deeper water where waves don t break l.jpg

An area of deeper water where waves don’t break


Rip current formation14 l.jpg

Rip Current Formation

What is 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.


B waves break on sandbars wave travels to the beach water runs off beach through a channel l.jpg

B. Waves break on sandbars, wave travels to the beach, water runs off beach through a channel.


Rip current formation16 l.jpg

Rip Current Formation

The longer the period between waves:

a. The longer the waves.

b. The faster the waves move.

c. The more momentum the waves carry.

d. A and B

e. A,B, and C


E a b and c l.jpg

E. a, b, and c

__________ is proportional to amplitude or height squared


Wave energy l.jpg

Wave energy


Rip current formation20 l.jpg

Rip Current Formation

When do rip currents become 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.


A during high surf conditions as the wave height and wave period increase l.jpg

a. During high surf conditions as the wave height and wave period increase.


Types of rip currents l.jpg

Types 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.


What is a flash rip current l.jpg

What is a Flash Rip Current?


Types of rip currents24 l.jpg

Types of Rip Currents

  • This type of rip current develops along jetties, piers, and groins.


What is a permanent rip current l.jpg

What is a Permanent rip current?


Types of rip currents26 l.jpg

Types of Rip Currents

  • This type of rip current is dependent upon shape of coast, bays, points, reefs or sand bars.


What is a fixed rip current l.jpg

What is a Fixed rip current?


Types of rip currents28 l.jpg

Types of Rip Currents

  • This type of rip current occurs with long shore (parallel to beach) current

  • Occurs with long shore (parallel to beach)current

  • Pushes rip away from original location and weakens it.


What is a traveling rip current l.jpg

What is a Traveling rip current?


Types of rip currents30 l.jpg

Types of Rip Currents

A long shore current may push swimmer into:

  • Flash rip current

  • Permanent rip current

  • Fixed rip current

  • All of the above


D all of the above31 l.jpg

D. All of the above


Rip currents safety l.jpg

Rip Currents Safety

T/F Rip currents do not pull people under the water—they pull people away from the shore.


Slide33 l.jpg

True


Rip currents safety34 l.jpg

Rip Currents Safety

T/F Undertow and riptides are the same as rip currents.


False l.jpg

False


Rip currents safety36 l.jpg

Rip Currents Safety

T/F Rip currents only occur on beaches near the ocean.


False they also occur in the great lakes l.jpg

False, they also occur in the Great Lakes.


Rip currents safety38 l.jpg

Rip Currents Safety

T/F Rip Currents can be very narrow or more than 50 yards wide.


Slide39 l.jpg

True
