Abstract

Dikes worldwide play a crucial role in mitigating flooding risks. Often, armour rocks are placed within the wave impact zone to protect the dike from wave loading. To ensure a dike is in optimal condition the assessment of the hydraulic stability of armour rocks is necessary. This study presents a Granulometric analysis technique, which is based on UAV photogrammetry and optical digital granulometry to evaluate the spatial distribution and possible variations in time of armour rocks granulometry and hydraulic stability. This is a new non-invasive technique with which spatial, temporal changes can be studied. Our study area is located in Camargue, south of France. This low-laying region, exposed to multiple storms, is among the most endangered zones by sea level rise. We concluded that monitoring of the dike is possible using this technology the optical granulometric analysis could be performed on UAV images. We conducted granulometry distribution calculations for armour rocks, even when they were covered with moss. Our findings show the spatial variation of granulometry along the dike. In specific areas of interest where hydraulic stability was assessed, based on the granulometry results, we have found areas with low hydraulic stability that need to be investigated more thoroughly.
