To use this online calculator for Significant Wave Height in terms of rms Surface Elevation, enter RMS Surface Elevation (η rms) and hit the calculate button. Terrain grades that are less than 1 (terrain grade <1) mean that the slope is gentle. An easy-to-remember equation for finding change in elevation as a decimal is “rise over run,” meaning the rise (the change in vertical distance) divided by the run (the change in horizontal distance). HI (Height of the Instrument) = 100 ft + 5 ft = 105 ft. Elevation of middle point = 105 ft – 6 ft = 99 ft. Elevation of new benchmark = 4.5 ft – 7.5 ft + 99 ft = 96 ft. Reciprocal levelling.
