Using Pleiades Satellite Imagery to Monitor Multi-Annual Coastal Dune Morphological Changes

Olivier Burvingt, Bruno Castelle, Vincent Marieu, Bertrand Lubac et autres

In the context of sea levels rising, monitoring spatial and temporal topographic changes along coastal dunes is crucial to understand their dynamics since they represent natural barriers against coastal flooding and large sources of sediment that can mitigate coastal erosion. Different technologies …

Sharp decline in surface water resources for agriculture and fisheries in the Lower Mekong Basin over 2000-2020

Cassandra Normandin, Frédéric Frappart, Luc Bourrel, Fabien Blarel et autres

Water resources play a crucial role in the global water cycle and are affected by human activities and climate change. However, the impacts of hydropower infrastructures on the surface water extent and volume cycle are not well known. We used a multi-satellite …

Monitoring the Temporal Evolution of the Floods in the Lower Mekong Basin using Multisatellite Observations

Frédéric Frappart, Cassandra Normandin, Fabien Blarel, Sylvain Biancamaria et autres

Surface water storage is an essential component of the hydrological cycle. Remote sensing offers valuable tools for monitoring both surface water extent from satellite images and water levels from radar altimetry. Combining both information, we were able to estimate the variations of …

Performance and Uncertainty of Satellite-Derived Bathymetry Empirical Approaches in an Energetic Coastal Environment

Bertrand Lubac, Olivier Burvingt, Alexandre Nicolae Lerma, Nadia Sénéchal

Objectives of this study are to evaluate the performance of different satellite-derived bathymetry (SDB) empirical models developed for multispectral satellite mission applications and to propose an uncertainty model based on inferential statistics. The study site is the Arcachon Bay inlet (France). A …

Classification of Atlantic Coastal Sand Dune Vegetation Using In Situ, UAV, and Airborne Hyperspectral Data

Quentin Laporte-Fauret, Bertrand Lubac, Bruno Castelle, Richard Michalet et autres

Mapping coastal dune vegetation is critical to understand dune mobility and resilience in the context of climate change, sea level rise, and increased anthropogenic pressure. However, the identification of plant species from remotely sensed data is tedious and limited to broad vegetation …

Nature-Based Solution along High-Energy Eroding Sandy Coasts: Preliminary Tests on the Reinstatement of Natural Dynamics in Reprofiled Coastal Dunes

Bruno Castelle, Quentin Laporte-Fauret, Vincent Marieu, Richard Michalet et autres

This paper describes a large-scale experiment designed to examine if reinstating natural processes in the coastal dune systems of Southwest France can be a relevant nature-based adaptation in chronically eroding sectors and a nature-based solution against coastal hazards, by maintaining the coastal …

Analysis of Suspended Sediment Variability in a Large Highly Turbid Estuary Using a 5‐Year‐Long Remotely Sensed Data Archive at High Resolution

Cassandra Normandin, Bertrand Lubac, Aldo Sottolichio, Frédéric Frappart et autres

Abstract Spatial variability of surface suspended particulate matter (SPM) concentration in the Gironde estuary and their relationships with environmental forcing are investigated through high spatial resolution multispectral data collected from July 2013 to August 2018 by the Operational Land Imager (Landsat‐8/OLI) and …

Monitoring Beach Topography and Nearshore Bathymetry Using Spaceborne Remote Sensing: A Review

Edward Salameh, Frédéric Frappart, Rafaël Almar, Paulo Baptista et autres

With high anthropogenic pressure and the effects of climate change (e.g., sea level rise) on coastal regions, there is a greater need for accurate and up-to-date information about the topography of these systems. Reliable topography and bathymetry information are fundamental parameters for …

Potential of High-Resolution Pléiades Imagery to Monitor Salt Marsh Evolution After Spartina Invasion

Bárbara Proença, Frédéric Frappart, Bertrand Lubac, Vincent Marieu et autres

An early assessment of biological invasions is important for initiating conservation strategies. Instrumental progress in high spatial resolution (HSR) multispectral satellite sensors greatly facilitates ecosystems’ monitoring capability at an increasingly smaller scale. However, species detection is still challenging in environments characterized by …

Evolution of the Performances of Radar Altimetry Missions from ERS-2 to Sentinel-3A over the Inner Niger Delta

Cassandra Normandin, Frédéric Frappart, Adama Telly Diepkilé, Vincent Marieu et autres

Radar altimetry provides unique information on water stages of inland hydro-systems. In this study, the performance of seven altimetry missions, among the most commonly used in land hydrology (i.e., European Remote-Sensing Satellite-2 (ERS-2), ENVIronment SATellite (ENVISAT), Satellite with Argos and ALtika (SARAL), …
