The longitudinal profile of a river has been regarded as a curve which resembles a hyperbola or exponential curve, tangent to the base level. A continuous profile of a graded river like this will break and tend to make a cusped point, if such kind of deformation as to make the gradient of the lower course from a point in it steeper than that of the iipper one, do occur. There are vertical movements as shown in Table I, 1-5, by Avhich cusped points will necessarily be formed.
