Beach profiling Ella E,

Materials
  • emery rods (1)
  • Writing utensil(1)
  • Beach profiling sheet (note sheet), (1)            
Methods
  1. Go to a beach.
  2. Find the wrack line. (Tide line)
  3. Take out your emery rods. (Emery rods are two poles with a taut rope tied in between)
  4. Take one pole and put on the slope (or flat land), and aline with the horizon.
  5. Take both poles  and put them on the wrack line, opposite of each other.
  6. Take the pole aligned with the horizon, and look what that mark is on the pole opposite to it.
  7. There will be numbers on the poles, the mark will be one of these numbers.  This is your data.
  8. Do this until all the data needed to find changes in the beach is found.

I. Procedure

    A.Materials
  • Emory rods
  • Recycling bucket
     B.Methods
  1. Go to the beach and find the high water mark.
  2. Then use the emery rods and set them straight having one at the high water mark and the other pointing to the water.
  3. Line up the rod pointing to the water with the horizon, and use your eye to line up the top of the rod with the horizon.
  4. Make an imaginary line from the rod to the emory rod at the high water mark and see what number the imaginary line hits.
  5. Keep doing this till you get to the water.

Materials
  • Wrackline
  • A horizon
  • Surface/ piece of land



Methods

  1. This process is called "Beach Profiling". During this process, you take your wrackline and straighten it out as best as possible.
  2.  BUT REMEMBER- Keep your wrackline STRAIGHT ( Vertically.) 
  3. Have one person hold one stick, while you hold the other.
  4. Match the top of your partners stick to the horizon
  5. Look at the number on your stick that matches with the top of your partners stick and the horizon
Once you find the number you are good to go, and ready to record in your note book. If you are interested in this process, than maybe you should come back to the same surface/ piece of land after a few weeks and see how it eroded.

Procedure
          A. Materials 
  • Emery Pole 
  • A slope 
  • Notebook
          B.Methods
  1. Put one side of the emery pole in the ground and focus on the horizon.
  2. Have your partner put the other pole on the beach.
  3. Then focus on the horizon and your partners pole.
  4. Then see were the horizon lines up with your partners pole and see were the horizon lines up on your partners stick.
  5. Were ever that lines up write the number on your notebook and compare it with the other profiles. 

Beach Profiling Sam H,

Procedure
A. Materials 
  • Slope
  • Emory pole
  • Notebook
B. Methods 
  1. Put one side of the Emory pole on the ground and make sure its straight up.
  2. Have your partner put the pole straight away from you.
  3. Put the other pole as far as you can away from the other so the rope is taunt.
  4. Look at the horizon and line up it with the top of the farthest pole top.
  5. Once there lined up look at the pole closest to you and measure where the horizon and the pole top line up. 
  6. Then write the measurements down in your notebook.

Emery Rods
Line
Sight Marker

Procdure

1. Set a control point.

2. Begin Notes.

3. Record Stake Height

4. Set Rod 1. Stand the end of one profile rod (Rod 1) on the ground
next to the control point with the numbers (scale) up. The person
holding this rod should stand off the profile line for the next step.

5. Set Rod 2. The second person takes Rod 2 toward the ocean.
Looking back toward land and Rod 1, this lead person places Rod 2
(with scale up) on the profile line using the control points as a
guide. Pick a horizontal distance of a meter (or other suitable
distance if obstacles are in the way) as a spacing between the two
poles. Use a graduated chain or pole to do this and be careful to
hold both poles straight up and down while setting Rod 2 in place.

6. Measure and Record. From the landward pole, the first person
sights the horizon and the top of the lower of the two rods. This
line-of-sight will intersect part way up the other rod. Read the
elevation number marked on the other rod that is in line with the pole
top and the horizon. Keep both poles vertical when reading!

7. Move Ahead. After the notes are taken, move Rod 1 to the same
“footprint” occupied by Rod 2. The person at Rod 2 should wait for
Rod 1 to come up alongside Rode 2 in order to be certain of getting
the position correct. After Rod 1 is in the place of Rod 2, the
forward rod can be moved ahead another meter or two and place o n the
ground in line with Rod 1 and the original control point(s). The job
of the lead person is to be sure each forward move stays on the line.
Rod 2 must be set down on the ground keeping the chain (or other tape
measure ) level.



8. Repeat Steps 6 and 7. Measure, Record, & Move. Continue to move
ahead, repeat these steps all the way to the water. As you go,
everyone on the team should look ahead for features to stop on and
measure. If some feature, perhaps the edge of the dune, does not
occur at a horizontal interval of one meter, then make the horizontal
distance smaller. For example, if the dune edge is only 0.6m from the
least measurement, move the forward pole ahead only that far. ON the
next measurement move ahead only 0.4 (or 1.4) m in order to get back
on a spacing of 1 m intervals. Keeping a set interval in whole meters
will help with data analysis later.



9. Stop at the Water.

10. Photograph the Beach. Take three photographs of the beach. It
helps to place the profile rods down on the profile line part way up
the beach, near the high-tide line. Stepping back from the rods, take
a picture looking up to the dune )or seawall) from a spot near the
water line. Move up about halfway on the profile and take two more
pictures: one looking each way along the beach (parallel to the water
line). For these shots try and include the profile rods in the
foreground. Frame the picture to include the beach from dune
(seawall) to the water.

Procedure
A. Materials
  • A Slope
  • Emory rode
  • A Horizon
  • A Notebook

B.Methods
  1. Put one emory rode at the edge of the beach. 
  2. Then stretch the other end of the emory rod as far as it can go down the beach.
  3. Then line up the the one closest to the end of the beach with the other one (make sure its straight).
  4. Then line up the top of the one closest to the end of the beach with the horizon 
  5. Then see were it lands on the one farthest from the end of the beach.
  6. Right down were it is.
  7. Then repeat it until you get to the end of the water.
