摘要

冲积水系的形态计量学分析有助于了解冲积水系的动力学、侵蚀能力、对洪水的易感性以及可能与构造断裂的成因关系。在这项研究中,我们分析了位于爱琴海北部的萨摩斯岛的排水系统。结果表明,该流域易受侵蚀和洪水事件的影响,这些强烈的现象主要集中在三级集水区。显示了两个不同的排水网络系统:一个以北西-东南方向为主的旧排水网络系统,包括四阶和五阶分支;一个以北东-西南方向为主的新排水网络系统,包括较小的新排水网络系统。主要构造断裂方向为NNW-SSE。海道网的分支和断裂呈现不同的方向,表明海道格局不受构造的影响。

Morphometric analysis of the drainage network of Samos Island (northern Aegean Sea): Insights into tectonic control and flood hazards

The morphometric analysis of alluvial drainage provides insights into its dynamics, erosion capacity, susceptibility to floods and possible genetic relations to tectonic faulting. In this study, we analysed the drainage system of Samos Island, located in the northern Aegean Sea. The results indicate a vulnerability to erosion and flooding events, and these intense phenomena concentrate mostly on third-order catchments. Two dissimilar drainage network systems are shown: an older drainage network system with a main NW–SE direction, which includes fourth- and fifth-order branches, and a recent drainage network system, which includes new, smaller order branches with a main NE–SW direction. The major tectonic fault orientations are NNW–SSE. The branches of the hydrographic network and faults present different directions, which indicates that the hydrographic pattern is not affected by tectonics.

期刊介绍: Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
