Geomorphology influences habitat distribution on barrier islands by regulating exposure to harsh abiotic conditions. Researchers have identified linkages between habitat and landscape position, such as elevation and distance from shore, yet these linkages have not been fully leveraged to develop predictive models. Our aim was to evaluate the performance of commonly used machine learning algorithms, including K-nearest neighbor, support vector machine, and random forest, for predicting barrier island habitats using landscape position for Dauphin Island, Alabama, USA. Landscape position predictors were extracted from topobathymetric data. Models were developed for three tidal zones: subtidal, intertidal, and supratidal\/upland. We used a contemporary habitat map to identify landscape position linkages for habitats, such as beach, dune, woody vegetation, and marsh. Deterministic accuracy, fuzzy accuracy, and hindcasting were used for validation. The random forest algorithm performed best for intertidal and supratidal\/upland habitats, while the K-nearest neighbor algorithm performed best for subtidal habitats. A posteriori application of expert rules based on theoretical understanding of barrier island habitats enhanced model results. For the contemporary model, deterministic overall accuracy was nearly 70%, and fuzzy overall accuracy was over 80%. For the hindcast model, deterministic overall accuracy was nearly 80%, and fuzzy overall accuracy was over 90%. We found machine learning algorithms were well-suited for predicting barrier island habitats using landscape position. Our model framework could be coupled with hydrodynamic geomorphologic models for forecasting habitats with accelerated sea-level rise, simulated storms, and restoration actions.<\/jats:p>","DOI":"10.3390\/rs11080976","type":"journal-article","created":{"date-parts":[[2019,4,25]],"date-time":"2019-04-25T03:02:59Z","timestamp":1556161379000},"page":"976","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Modeling Barrier Island Habitats Using Landscape Position Information"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7887-3261","authenticated-orcid":false,"given":"Nicholas M.","family":"Enwright","sequence":"first","affiliation":[{"name":"U.S. Geological Survey, Wetland and Aquatic Research Center, Lafayette, LA 70506, USA"},{"name":"Louisiana State University, Department of Geography and Anthropology, Baton Rouge, LA 70803, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1298-4839","authenticated-orcid":false,"given":"Lei","family":"Wang","sequence":"additional","affiliation":[{"name":"Louisiana State University, Department of Geography and Anthropology, Baton Rouge, LA 70803, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2977-7732","authenticated-orcid":false,"given":"Hongqing","family":"Wang","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey, Wetland and Aquatic Research Center, Baton Rouge, LA 70803, USA"}]},{"given":"Michael J.","family":"Osland","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey, Wetland and Aquatic Research Center, Lafayette, LA 70506, USA"}]},{"given":"Laura C.","family":"Feher","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey, Wetland and Aquatic Research Center, Lafayette, LA 70506, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6665-7115","authenticated-orcid":false,"given":"Sin\u00e9ad M.","family":"Borchert","sequence":"additional","affiliation":[{"name":"Borchert Consulting at the U.S. Geological Survey, Wetland and Aquatic Research Center, Lafayette, LA 70506, USA"}]},{"given":"Richard H.","family":"Day","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey, Wetland and Aquatic Research Center, Lafayette, LA 70506, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/0025-3227(85)90077-5","article-title":"The Barrier Island System","volume":"63","author":"Oertel","year":"1985","journal-title":"Mar.
