Abstract: The authors try to use conceptual model, mathematical model and computer model to reconstruct the formation and evolution of dynamic geomorphic features of tectonic gulches. Meanwhile, they take the gulch on terrace Ⅲ in Hongshanzui power station on the west bank of the Manasi River, Xinjiang, as an example to dynamically visualize the models. The models and visualization system are in accordance with the gulch development rule in the study area, so they can be used for reconstructing ancient and predicting future shapes of different gulches.
