A new shoreline change assessment approach for erosion management strategies
2022
Shoreline evolution studies are fundamental to assess the rate of beach accretion or retreatment. In the last years, researchers developed many methods with several techniques belonging to different disciplines and backgrounds. Nowadays, the Shoreline Change Analysis (SCA) is the most widespread method to assess shoreline evolution. In fact, the SCA is needed to perform management strategies able to respond to current erosion or potential future erosion problems. This paper presents a new approach using an automatic method for SCA with accuracy and speed improvements. Indeed, in the framework of the management of coastal erosion and to develop an adaptation plan to coastal hazards it is nec…
Decadal evolution of coastline armouring along the Mediterranean Andalusia littoral (South of Spain)
2016
Abstract Emplacement of hard coastal defence structures, such as seawalls, revetments, groins and breakwaters, or even ports, harbours and marinas, is commonly known as coastline armouring. This paper deals with coastal armouring evolution along the 546 km Mediterranean coast of Andalusia (Spain). It is based on photo interpretation and GIS tools, which have been employed to map coastal structure emplacement and evolution by analysis of 1956, 1977, 2001 and 2010 aerial photos. Additionally the coefficient of infrastructural impact K , which represented the relation between the total length of maritime structures and the length of the study coastal section, was obtained - i.e. minimal at 0.0…
