However, their complex morphodynamics, associated with a wide range of physical and biological processes, are still poorly understood and require further field investigation. In addition, mudflats are challenging areas for Structure-from-Motion (SfM) photogrammetric surveys. Indeed, the mudflats generally hold back residual tidal water, which can make stereo restitution particularly difficult because of poor correlations or sun-glint effects. This study aims to show the potential of light UAVs (Unmanned Aerial Vehicles) for monitoring sedimentary hydrodynamics at different spatial scales in a silty estuary. For each UAV mission an orthophotograph and a Digital Elevation Model (DEM) are computed. From repeated surveys the diachronic evolution of the area can be observed via DEM differencing. Considering the ground texture in such a context, the stereo restitution process is made possible because of the high spatial resolution of the UAV photographs. Providing a synoptic view as well as high spatial resolution (less than 4 cm), the UAV dataset enables multi-scale approaches from the study of large areas to the morphodynamics of smaller-scale sedimentary structures and the morphodynamics impact of plant ground cover.<\/jats:p>","DOI":"10.3390\/ijgi5040050","type":"journal-article","created":{"date-parts":[[2016,4,13]],"date-time":"2016-04-13T10:08:06Z","timestamp":1460542086000},"page":"50","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":68,"title":["Potential of UAVs for Monitoring Mudflat Morphodynamics (Application to the Seine Estuary, France)"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7629-9710","authenticated-orcid":false,"given":"Marion","family":"Jaud","sequence":"first","affiliation":[{"name":"Domaines Oc\u00e9aniques - UMR 6538, Universit\u00e9 de Bretagne Occidentale, IUEM, Technop\u00f4le Brest-Iroise, Rue Dumont D\u2019Urville, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florent","family":"Grasso","sequence":"additional","affiliation":[{"name":"Ifremer - Dyneco\/Physed - Centre de Bretagne, BP 70, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Le Dantec","sequence":"additional","affiliation":[{"name":"Domaines Oc\u00e9aniques - UMR 6538, Universit\u00e9 de Bretagne Occidentale, IUEM, Technop\u00f4le Brest-Iroise, Rue Dumont D\u2019Urville, F-29280 Plouzan\u00e9, France"},{"name":"CEREMA - Centre d\u2019Etudes et d\u2019expertise sur les Risques, l\u2019Environnement, la Mobilit\u00e9 et l\u2019Am\u00e9nagement, DTechEMF, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romaric","family":"Verney","sequence":"additional","affiliation":[{"name":"Ifremer - Dyneco\/Physed - Centre de Bretagne, BP 70, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christophe","family":"Delacourt","sequence":"additional","affiliation":[{"name":"Domaines Oc\u00e9aniques - UMR 6538, Universit\u00e9 de Bretagne Occidentale, IUEM, Technop\u00f4le Brest-Iroise, Rue Dumont D\u2019Urville, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00f4me","family":"Ammann","sequence":"additional","affiliation":[{"name":"Domaines Oc\u00e9aniques - UMR 6538, Universit\u00e9 de Bretagne Occidentale, IUEM, Technop\u00f4le Brest-Iroise, Rue Dumont D\u2019Urville, F-29280 Plouzan\u00e9, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien","family":"Deloffre","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Rouen, M2C, UMR 6143, CNRS, Morphodynamique Continentale et C\u00f4ti\u00e8re, F-76821 Mont Saint Aignan Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Grandjean","sequence":"additional","affiliation":[{"name":"Laboratoire de G\u00e9ologie de Lyon - UMR 5276, Universit\u00e9 Claude Bernard Lyon 1, Campus de la Doua, 2 rue Rapha\u00ebl Dubois, F-69622 Villeurbanne Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"710","DOI":"10.1016\/j.ecss.2005.04.004","article-title":"Sedimentary processes on an intertidal mudflat in the upper macrotidal Seine estuary, France","volume":"64","author":"Deloffre","year":"2005","journal-title":"Estuar.
