One of the most conspicuous features of a mountain belt is the main drainage divide. Divide location is influenced by a number of parameters, including tectonic uplift and horizontal advection. Thus, the topography of mountain belts can be used as an archive to extract tectonic information. Here we combine numerical landscape evolution modelling and analytical solutions to demonstrate that mountain asymmetry, determined by the location of the main drainage divide, increases with increasing uplift gradient and advection velocity. Then, we provide a conceptual framework to constrain the present or previous tectonic uplift and advection of a mountain belt from the location and migration direction of its main drainage divide. Furthermore, we apply our model to Wula Shan horst, Northeastern Sicily, and Southern Taiwan.
山脉带最显著的特征之一是主要分水岭。分水岭的位置受多种参数影响，包括构造隆升和水平平流。因此，山脉带的地形可作为提取构造信息的档案。在此，我们结合数值地貌演化建模和解析解来证明，由主要分水岭位置决定的山脉不对称性会随着隆升梯度和平流速度的增加而增大。然后，我们提供一个概念框架，以便根据山脉带主要分水岭的位置和迁移方向来约束其当前或先前的构造隆升和平流。此外，我们将我们的模型应用于乌拉山地垒、西西里岛东北部和台湾南部。
