WebThere are five slope classifications designated by the letters C, M , S, A, and H (critical, mild, steep, adverse, and horizontal) respectively. Mild (M) if y n > y c Steep (S) if y n < y c Critical (C) if y n = y c Adverse (A) if So < 0 (if slope is positive in the downstream direction) Horizontal (H) if So = 0 http://www.its.caltech.edu/~ce112/chapter3text.pdf
