How to measure Beach gradient with a clinometer and rulers?
how would you measure the gradient of a beach with a clinometer and rulers, or even just a clinometer. if you could tell me in detail i would be very greatfull thanks.
The essential parts of a clinometer are a flat side, or base, on which it stands, and a hollow disk just half filled with some heavy liquid. The glass face of the disk is surrounded by a graduated scale that marks the angle at which the surface of the liquid stands, with reference to the flat base. The line 0.—0. being parallel to the base, when the liquid stands on that line, the flat side is horizontal; the line 90.—90. being perpendicular to the base, when the liquid stands on that line, the flat side is perpendicular or plumb. Intervening angles are marked, and, with the aid of simple conversion tables, the instrument indicates the rate of fall per set distance of horizontal measurement, and set distance of the sloping line.
Step
1
Position yourself at the required distance from the object you want to measure. The distance, referred to as the baseline distance, varies by clinometer type. For example, the baseline distance for a metric clinometer might be 15 meters.
Step
2
Hold the clinometer right-side up in one hand. The information printed on the lens in the clinometer only provides accurate information when you hold the clinometer right-side up, and the "up" side is indicated on the clinometer’s case.
Step
3
Look with one eye through the lens at the object you want to measure. The scale on the clinometer’s lens will be visually projected onto the object.
Step
4
Visually position the object against the scale displayed on the clinometer’s lens. Note the values on the scale for the base and top of the object. Using a metric clinometer to measure the height of a pole, you might observe that the base of the pole aligns with the number three on the clinometer lens’s scale and the top of the pole aligns with the number six.
Step
5
Subtract the bottom value from the top value to determine the height of the object in units based on your clinometer’s type. In this example, the top value for the pole is six and the bottom value is three. Subtracting six from three yields the measurement of three meters in height for the pole.
