  abstract = {{W}e present a new geomorphological analysis of the {T}inee {R}iver tributaries in the southern {F}rench {A}lps based on numerical inverse and forward modelling of their longitudinal profiles. {W}e model their relative uplift history with respect to the main channel, hence the incision rate history of this channel. {I}nverse models show that all tributaries have consistent incision rate histories with alternating high and low values. {A} comparison with global temperature curves shows that these variations correlate with quaternary climate changes. {W}e suggest that during warm periods, a wave of regressive erosion propagates in the {T}inee {R}iver, while its tributaries deeply incise their substratum to catch up with the falling base level. {W}e also show that the post 140 ka history of this landscape evolution is dominated by fluvial incision. {W}e then perform forward models of river incision and simulate the incision of the {T}inee {R}iver system over a time span of 600 ka. {T}his model allows us to extract time and space incision rate variations of the {T}inee {R}iver. {W}ith a background of a few mm.yr(-1), incision rate can increase up to more than 1 cm yr(-1) during short periods of time due to climatic oscillations. {T}his result is compatible with published cosmogenic nuclide based dating, which evidenced incision rates from 0.2 to 24 mm yr(-1). {T}he part of the channel located between 12 and 20 km downstream from the source has undergone several periods of rapid incision rates, which could explain the steep hillslopes and the triggering of a landslide similar to 10 ka ago.},
