Abstract Satellite remote sensing is becoming a widely used monitoring technique in coastal sciences. Yet, no benchmarking studies exist that compare the performance of popular satellite-derived shoreline mapping algorithms against standardized sets inputs and validation data. Here we present new framework to evaluate accuracy change observations extracted from publicly available satellite imagery (Landsat Sentinel-2). Accuracy precision five established are evaluated at four sandy beaches...
This paper evaluates the accuracy of shoreline positions obtained from infrared (IR) bands Landsat 7, 8, and Sentinel-2 imagery on natural beaches. A workflow for sub-pixel extraction, already tested seawalls, is used. The present work analyzes behavior that resultant shorelines a micro-tidal (<20 cm) sandy beach makes comparison with other more accurate sets shorelines. These were using differential GNSS surveys terrestrial photogrammetry techniques through C-Pro monitoring system. 21...
SAET (Shoreline Analysis and Extraction Tool) is a novel open-source tool to enable the completely automatic detection of shoreline position changes using optical imagery acquired by Sentinel-2 Landsat 8 9 satellites. has been developed within ECFAS (European Coastal Flood Awareness System) project, which intended be first European service for coastal flood forecasting, management, recovery analysis. The characterise response associated with punctual events such as storms well any other...

Sandy coastlines are very dynamic spaces affected by a variety of natural and human factors. In Central Chile, changes in oceanographic wave conditions, modes inter-annual climate variability such as El Niño Southern Oscillation (ENSO), extreme events earthquakes tsunamis condition the beach morphology. At same time, direct actions alter arrival sediments to coast their alongshore distribution. Despite relevance beaches for this coastal region interesting relationship morphology has with...
High costs and project-based (short-term) financing mean that coastal engineering projects are often undertaken in the absence of appropriate post-construction monitoring programmes. Consequently, performance shoreline-stabilizing structures or beach nourishments cannot be properly quantified. Given high value beaches increase erosion problems responses, managers require as much accurate data possible to support efficient decision-making. This work presents a methodological approach...
This study explores the potential of repurposing historical aerial photographs to produce high-accuracy digital surface models (DSMs) at regional scales. A novel methodology is introduced, incorporating road points for quality control and refinement enhance precision comparability multitemporal DSMs. The method consists two phases. first photogrammetric phase, where DSMs are generated using structure from motion (SfM) techniques. second which uses a large number (millions) extracted...
Satellite-Derived Waterlines (SDWs) have become highly valuable assets in coastal studies due to their extensive data availability, offering temporal and spatial resolutions of up 5 days 10 m, respectively. Numerous tools for SDW extraction been developed, being widely used microtidal beaches with high reliability. However, macrotidal environments present significant challenges large intertidal extensions. The dynamic nature complex morphology these areas frequently lead inaccuracies...
Dunes and beaches are highly dynamic interrelated spaces of great environmental social interest. The sediment displacement occurs at diverse temporal scales, both alongshore cross-shore, with an important interaction the foredune. Remote sensing techniques beginning to provide approaches for monitoring different spatial scales. While two-dimensional characterisation is possible high accuracy by defining changes in waterline position from optical satellite imagery, a holistic view sedimentary...
The Torreblanca gravel barrier, a 9.4-km-long ridge along the Valencian coast (E Spain), encloses Albufera de Lagoon and is undergoing rapid geomorphological evolution, characterised by significant landward migration in recent decades. tens of metres wide, predominantly composed coarse pebbles (some exceeding 7 cm diameter). It features rising approximately 2.5 m above sea level, steep seaward slope (>40&#186;), numerous washover fans, submerged beach deposits containing peat layers...
Multi-temporal analysis is one of the main applications remote sensing, and Landsat imagery has been resources for many years. However, moderate spatial resolution (30 m) restricts their use high precision applications. In this paper, we simulate scenes to evaluate, by means an exhaustive number tests, a subpixel registration process based on phase correlation upsampling Fourier transform. From image (0.5 m), two sets 121 synthetic images fixed translations are created m). sense, point...
