最近（25年）的形态动力学的一个冰前到达的里丹纳河，东北意大利，在没有人为的限制，已经调查了密集的现场活动和航空照片的分析。研究河段多呈辫状形态，下游河谷比降、泥沙粒径及主槽内形成条件变化剧烈。这些不连续性与在不同的时间尺度，这已被量化耦合水文与形态信息的通道调整的不同过程。
The recent (25 years) morphodynamics of a proglacial reach of the Ridanna Creek, North‐East Italy, evolving in the absence of human constraints, has been investigated by means of an intensive field activity and of the analysis of aerial photographs. The study reach mostly displays a braided morphology, with sharp downstream variations of valley gradient, sediment size and formative conditions within the main channel. These discontinuities are associated with different processes of channel adjustment at different timescales, which have been quantified by coupling hydrological with morphological information.
