![]() For example, for the next measurement person A, holding the single meter stick, would stand at 19 m and person B, holding the transit pole, would stand at 18 m. ![]() Continue to collect data every meter along your transect, always keeping the meter sticks one meter apart.Record value on the beach profile data sheet (see example, Table 5.4).You will get negative readings if Person B is lower than Person A (as seen in Fig. If Person B’s finger moves up, the value read is negative (e.g., –5 cm). You will get positive readings if Person B is higher than Person A. If Person B’s finger moves down on the transit pole, the value read is positive (e.g., +5 cm).Person B will move their finger on their transit pole until his or her finger aligns with the horizon and the top of Person A’s meter stick (Fig.If you are using a meter stick, and your stick has a hole on one end, you can use it as your sighting hole for this activity. ![]() Person A will look along the top edge or through the sighting hole of the transit pole or meter stick to the horizon.Use the horizon, where the water meets the sky, to determine the vertical distance the beach slopes between the two transit poles.The measurements on this transit pole should face Person A’s transit pole. If you do not have a commercial transit pole, this person would hold the taped-together meter sticks as a transit pole, with the “positive” side towards the sand. Person B puts the second transit pole one meter away (at 19 m) on the transect.You can use a level to make sure the pole is vertical. Person A stands at the end of the transect (20 m from the waters’ edge) and holds the single meter stick or a transit pole vertically.If the tide is rising, start at the edge of the transect next to the water. Your transect length may be longer or shorter than 20 m. You may use smaller intervals if your beach is narrow. These directions are written starting at the costal edge of the transect and assume a transect length of 20 m and interval of 1 m. Measure the beach profile at regular intervals using a two person method.Draw your study location, including the location and distance of each transect line, the features at the beginning and end of the transect lines, the water conditions, and other coastal features.(Optional) Take GPS points to mark the location of each transect line.Record the distance between each transect line and between each transect line and a reference point, such as a tree or trashcan, so that you can easily find the location of your transect line again.The zero centimeter mark of the transect line should be at the edge of the water.However, you may have to start your transect at a higher water line depending on the tide and water conditions. Your transect should run from the shoreline (mean low tide level) to a pre- determined location, such as a certain number of meters onshore or to the vegetation line. ![]()
