From river valley to estuary : the early-mid Holocene transgression of the Rhine-Meuse valley, The Netherlands
Most present day estuaries formed within incised fluvial valleys, created during the last glacial, that drowned during post-glacial sea-level rise. The sedimentary archive of the associated river-mouth areas contains important information on estuarine evolution under different rates of sea-level ris...

Most present day estuaries formed within incised fluvial valleys, created during the last glacial, that drowned during post-glacial sea-level rise. The sedimentary archive of the associated river-mouth areas contains important information on estuarine evolution under different rates of sea-level rise. This thesis presents a study on the development of the mouth of the Rhine-Meuse system in the Rotterdam area, western Netherlands, between 12000-6000 BP. During the study tens of thousands of core descriptions and cone penetration test results, as well as seismic data, pollen and diatom analyses, tens of OSL-dates and hundreds of radiocarbon dates were used. The objectives were to explain: 1) the early-mid Holocene sedimentary succession of the Rhine-Meuse river-mouth area; 2) the development of the river-mouth area in the early-mid Holocene in response to rapid sea-level rise (SLR) and 3) the interaction of the fluvial and coastal systems during the early-mid Holocene transgression.
