The relation between tectonic deformation and surface process is a research front in recent years. European geologists study on the relationship between tectonic deformation and surface process and make some new progress, especially a coupling relationship between fold thrust belt deformation and surface processes at the smaller length scale. It has altered the traditional concept that tectonic deformation effects on surface processes with one-way control, and the new idea that the transverse river cutting could influence anticline deformation style is put forward. Deformation is influenced by surface processes and terrain slope (tectonic deformation), and there is a two-way coupling between the transverse river cutting and anticline deformation. The research with a numerical model shows that surface processes (mainly fluvial) effect deformation folding through the distribution change of the overlying material weight. Anticline deformation styles are not strongly influenced by lateral erosion of river incision. In order to study the interplay between structure deformation and transverse river at the piedmont region, it should not only consider the influence of tectonic deformation on the river, but also take the active role of river incised erosion, as well as climate factors into account. Therefore, the results provide a new thinking for basin and mountain coupling dynamics.
