Comparisons with records of historic floods support the interpretation of flood deposits and suggest that most recorded flood events are the result of intense meso-scale precipitation events. As there is no evidence for any major changes in erosion processes in the catchment since the Medieval Warm Period (MWP), we interpret the Allos record in terms of repeated intense precipitation events over the last millennium, with a low flood frequency during the MWP and more frequent and more intense events during the Little Ice Age. This interpretation is consistent with the pattern of increasingly humid conditions in the northwestern Mediterranean region. This long-term trend is superimposed on high frequency oscillations that correlate with solar activity and autumnal North Atlantic Oscillation (NAO). Finally, a comparison of flood records across the northwestern Mediterranean region showed that intense precipitation events in Allos (east of the Rhône Valley) were out of phase with events in the Cévennes (west of the Rhône) but in phase with events in eastern Spain. Supported by meteorological analyses, this suggests an oscillation in atmospheric circulation patterns over the northwestern Mediterranean.","pubRank":"1"}],"site":[{"NOAASiteId":"53133","siteName":"Lake Allos","siteCode":null,"mappable":"Y","locationName":"Continent>Europe>Western Europe>France","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["44.236","6.7092"]},"properties":{"southernmostLatitude":"44.236","northernmostLatitude":"44.236","westernmostLongitude":"6.7092","easternmostLongitude":"6.7092","minElevationMeters":"2230","maxElevationMeters":"2230"}},"paleoData":[{"dataTableName":"ALO09P13","NOAADataTableId":"22509","earliestYear":650,"mostRecentYear":2009,"timeUnit":"CE","earliestYearBP":1300,"mostRecentYearBP":-59,"earliestYearCE":650,"mostRecentYearCE":2009,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleolimnology/europe/france/allos2012.txt","urlDescription":"Data","linkText":"allos2012.txt","variables":[{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"formation property>event layer","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"dimensionless>count","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"flood events","cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"formation property>event layer","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"length unit>millimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"flood events","cvFormat":"Numeric","cvShortName":null}],"NOAAKeywords":["earth science>paleoclimate>paleolimnology>physical properties"]},{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleolimnology/europe/france/allos2012.xls","urlDescription":"Data","linkText":"allos2012.xls","variables":[],"NOAAKeywords":["earth science>paleoclimate>paleolimnology>physical properties"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
