Short summary

We choose the large Saryjaz river from South Tian Shan to analyse topographic and fluvial metrics. By quantifying the spatial distribution of major metrics and comparing with modelling patterns, we suggest that the observed transience was triggered by a big capture event during the Plio-Pleistocene and potentially affected by both tectonic and climate factors. This conclusion underlines the importance of local contingent factors in driving drainage development.
