instability. The steeper part of the slope gets adjustment through slides and thus
retreats backward setting a gentle and graded slope at its base which is suf

ciently

steeper to release kinetic energy suf cient only to transport already eroded mate-

rials. Thus the graded condition gradually moves upslope from the confluence
point. The deposition at the middle part and erosion at the upper reach and again
erosion at the lower section through further down cutting execute the concept of
complex response following Chorley et al. ( 1985 ).
