The amount of wrack deposited and retained on a beach may be affected by the beach’s morphology. Conversely, wrack deposits have the potential to modify sediment dynamics on the beach face through accumulation and erosion of sediments around wrack deposits, and the incorporation of organic matter into beach sands. The aims of this chapter were thus to determine whether beach morphology differed...

The present work deals with storm classification, using the Storm Power Index, and beach morphological response to storm events in the Gulf of Cadiz (SW Spain). Over the 1958–2001 period, 377 events divided into five classes ranging from ‘weak’ to ‘extreme’ were characterized. Classes I (weak) and II (moderate) accounted for 60% and 23% of events, respectively. Class III (significant), were 9% ...

The coastal area at Riccione, in the southern Emilia-Romagna littoral region, is exposed to erosive processes, which are expected be enhanced by climate change. beach, mostly composed of fine sand, maintained through various defense strategies, including frequent nourishment interventions for balancing sediment deficit and other experimental solutions reducing erosion. Artificial reshaping beac...

A study of the state coast Puerto Rico was conducted in 10 municipalities for 2017 to 2018 period. The main goal this evaluation is identify beach Post- Hurricane María (September 2017) at municipality level. using integration remote sensing techniques (high resolution images; unmanned aerial vehicles (UAV), Geographic Information Systems (GIS), geospatial database design and field work.

We investigate erosion patterns observed in a horizontal granular bed resulting from seepage of water motivated by observation of beach rills and channel growth in larger scale land forms. Our experimental apparatus consists of a wide rectangular box filled with glass beads with a narrow opening in one of the side walls from which eroded grains can exit. Quantitative data on the shape of the pa...

Increased coastal human intervention and climate change are leading to rapid changes in areas often causing catastrophic damage resident populations. The ShorelineS model was introduced, which can explain drastic beach were simulated. According the modeling results, installation of Gungchon Port caused sedimentation south port. It reviewed that erosion tendency is changed after breakwater front...

Abstract Beach rotation is a widely described process characterized by periodic alternations in sediment transport involving erosion at one end of the beach and accretion other. The 1500-km-long coast Guianas, South America, unique system dominated large migrating mud banks, muddy, mangrove-rich shorelines, rare sandy beaches. Interactions between waves beaches on this are affected banks which ...

Despite the large number of tsunamis that impact Mexico's Pacific coast, stratigraphic studies focusing on geological impacts are scanty, making it difficult to assess the long-term risks for this vulnerable region. Surface samples and six cores were taken from Laguna Mitla near Acapulco to examine sedimentological and geochemical evidence for marine incursion events. Sediment cores collected f...
