“…The movement of normal faults is usually parallel to a valley and may cause avulsion by lateral tilting of the valley floor. Alternatively, movement of normal listric faults generally cuts across a valley and may cause avulsion by changing the longitudinal gradient downdip of a rollover anticline (Mike, 1975;Bridge and Leeder, 1979;Ouich, 1985;Alexander and Leeder, 1987;Singh et al, 1993;Mackey and Bridge, 1995;Gawthorpe and Leeder, 2000;Peakall et al, 2000;Mack and Madoff, 2005;Maynard, 2006). Since faults maintain the same location for extended periods, the effect on fluvial systems is concentrated and tends to induce nodal avulsions (Southamer and Berendsen, 2000;Maynard, 2006).…”
