Figure 15.26. Development of segmented alluvial fan in response to the different uplift rate of the
mountain front. In the upper sketch uplift and aggradation rates are bigger than channel incision. In the
lower sketch channel incision is bigger than uplift. In this case active depositional zone has shifted
downfan as consequence of channel entrenchment an intersection point development giving place to a
telescopic fan (Bull, 1977).
