Levelling and surveying methods are also used for measurements of river channel and lake configurations Often, less accurate methods can be used for this work than for waterlevel recording stations, although the techniques are common 32 Definitions Differential levelling is the term applied to any method of measuring directly with a graduatedAnd return is the motion of the follower toward the cam center There are many follower motions that can be used for the rises and the returns In this chapter, we describe a number of basic curves Figure 611 Motion eventsRise and Fall Method In this method, the difference between consecutive points is calculated by comparing each point after the first with that immediately preceding it The difference of their staff reading indicates rise or fall according as any staff reading is smaller or greater than that at the preceding point
Look at the table below Column 1 is the angle in degrees Column 2 is the rise over run percentage for that angle (The trigonometric definition for column 2 is the tangent of that angle times 100 It is also the grade for that angle) Column 3 is the rise over slope length (or hypotenuse) percentage for that angle (or sine of that angleCheck = ∑BS∑FS = ∑rise = ∑fall = first RL – last RL =5964=6916=2842=3794= =0952 0952 0952 4 The following consecutive readings were taken with a level and 5 m levelling staff on continuously sloping ground at common intervals of m
