ABSTRACT

Ria-type estuaries correspond to complex systems at the transition between the continental and the marine domains, within a context of rocky coastlines. The Belon Estuary, in South Brittanny (France), is described as a typical ria-type estuary characterised by complex morpho-sedimentological facies, strongly influenced by the South Brittany’s geological framework. The characterisation of the morpho-sedimentological patterns is sourced from recent multi-data acquisition with acoustic remote sensors coupled to ground truth data. The Main Map synthesises the main results of this study concerning the hydro-morphological and sedimentological characterisation of the Belon estuary. This study adds up to former studies over ria-type estuaries and lay out the base for future studies on the hydrodynamic of complex rias, as the Belon estuary.

摘要

Ria 型河口对应于大陆和海洋域之间过渡的复杂系统，位于岩石海岸线的背景下。位于南布列塔尼（法国）的贝隆河口被描述为典型的河口型河口，其特征是复杂的地貌沉积相，受到南布列塔尼地质框架的强烈影响。形态沉积模式的表征来源于最近使用声学遥感器与地面实况数据进行的多数据采集。主地图综合了这项研究的主要结果，涉及 Belon 河口的水文形态和沉积学特征。这项研究补充了以前对河口型河口的研究，并为未来对复杂河口（如贝隆河口）的水动力研究奠定了基础。
