Reconstructing extreme discharge events A case study applying LOI for core-to-core validation of flood event registration
MetadataShow full item record
In this explorative study, four cores from three closely spaced infilled-channel sites are analyzed to investigate the reproducibility of flood event registration in fluvial-deltaic environments. The influence of channel fill architecture, i.e. the effect of position of the core in a residual channel, is examined. The application of Loss On Ignition (LOI) –applicability, reliability, and optimal methodology – is investigated. The aim is to establish an event layer correlation between the obtained cores within one residual channel in both longitudinal and lateral direction and deliver proof of the concept of cross correlation of flood event records between these sites.
