interval in whole meters will help with data analysis later. 16. Stop at the Water. Make a measurement that includes the water line. IN the notes column of the log sheet abbreviate it W.L. and record the TIME it was measured. Because the height of the tide is changing, the time of the reading is important. Estimate the place on the beach where the water level would be without the waves, the still water level. There is no need to measure how far up the beach the swash is going at the time of the measurement. 17. Continue On (Optional). The process can be continued into the water if teams want to. This is optional and not necessary. In cold water there is a risk of hypothermia. In rough seas there is a risk of getting hit by breaking waves. Do not take chances. Always keep your personal safety and that of your team members in mind. A few extra points on a graph are not worth the risk of personal injury. 18. Final Reading. At the last measurement, record the TIME finished on the log sheet. 19. 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. 20. Pack Up. Gather up all the field gear, including notes and any posts back at the control points.

Longshore Current Measurement Longshore currents affect shorelines by redistributing sand and sediment along their path. This redistribution is also known as littoral drift. Longshore currents form because waves are continuous and, in most cases, approach the shore at an angle. When a wave enters shallow water it is slowed by the rising sandy or rocky bottom that is rising upward making a shallow edge. This friction eventually causes breakers (the water you see toppling over at the water’s edge). As one wave meets the shore and breaks, another wave is right behind it, preventing the broken wave from flowing backward. This causes a “build-up” of water at the shoreline. This “build-up” of water is then forced to form a current that flows parallel to the shore close to the water’s edge. Equipment: Tape measure to measure off 10 meters, at least two oranges or pieces of driftwood; a stopwatch or a wristwatch with a second hand. Procedure: 1. Measure and mark off a 10-meter long line parallel to the ocean. 2. Determine which direction the longshore current is flowing by tossing an orange into the water just beyond the breakers. Observe to see which direction the orange drifts. 3. Post one person each at the beginning and end of the 10-meter line and instruct them to look straight ahead towards the water. Supply the person at the beginning of the line (the direction from which the current is coming) with a stopwatch or a wristwatch with a second hand. 4. Go to the water’s edge slightly past the beginning of the line and toss an orange or piece of driftwood into the breakers (just behind the white foam at the top of the wave). When the orange passes the start line the person there should start timing. 5. The person at the other end should signal the timekeeper as soon as the orange passes his or her post. The time is then recorded and the data sheet (page 79) is used to calculate the speed or the velocity of the longshore current.
