Abundant numbers of sites and studies exist in NW Europe that document the geographically and geomorphologically diverse coastal record from the Last Interglacial (Eemian, Ipswichian, Marine Isotope Stage 5e). This paper summarises a database of 146 known Last Interglacial sea-level data points from in and around the North Sea (35 entries in the Ne...
Article
Full-text available
In the unconstrained, low gradient setting of major delta plains, individual meander belts tend to function for relatively short periods of time due to repeated channel avulsion. Their short lifetime makes ‘deltaic’ channel belts suitable to study the products of steady meander evolution as the deposits and internal architectural elements preserved...
Article
Reconstructing water levels reached during past floods contributes to fluvial system understanding and flood risk assessments. For methodological restrictions, this type of research is usually conducted in confined valley settings. In this study, we expand upon that geomorphological context by reconstructing extreme flood levels in a lowland delta...

Article
Full-text available
Dike failure due to piping – concentrated flow of seepage water underneath the dike during periods of high flood water levels – has been recognized as a major component of flood risk. Simulation models to predict piping in risk assessments require detailed information on subsurface characteristics such as sediment grain size and thickness of overbu...
Article
Full-text available
Connecting geologically mapped data to numerical modelling can help in understanding river landscape evolution. This study focuses on flood-induced breaching of the coversand ridge in the IJssel valley floodplain (Rhine delta, the Netherlands). The development of the breach would explain why this river branch came into existence in early medieval t...

The tectonic andfluvial setting of the Rhine-Meuse river system in the Lower Rhine Embayment rift system is ex-ceptionally well known. The 19th century, pre-regulation river courses of three rivers are used to study a postu-lated sinuosity response to faulting. The fault-perpendicular Meuse River shows patterns of sinuosity changes atdifferent spat...
Article
While recent landscape changes can be usually easily read through accessible morphological features, relatively ancient processes can be difficult to detect as the associated morphologies and deposits are often buried below younger sediments. With the aim of understanding the evolution of the distal Venetian-Friulian Plain (NE Italy) after the Last...
Article
Full-text available
Palaeoflood hydraulic modelling is essential for quantifying ‘millennial flood’ events not covered in the instrumental record. Palaeoflood modelling research has largely focused on one‐dimensional analysis for geomorphologically stable fluvial settings, because two‐dimensional analysis for dynamic alluvial settings is time‐consuming and requires a...
Conference Paper
Full-text available
Coversand ridges are natural elevated areas that formed in the last part of the glacial period due to wind transport. Some coversand ridges created a watershed between the Rhine and IJssel floodplain. Erosion of these cover-sand ridges was of major influence for the formation of the river IJssel as a Rhine delta distributary. A coupled hydrodynamic...
Article
Full-text available
Reconstruction of past topography in palaeo-DEMs serves various geomorphological analyses. Constructing a palaeo-DEM by stripping young elements from a LiDAR DEM can provide results for large study areas at high resolution. However, such a ‘top-down’ approach is more suited to recent periods and geomorphologically static parts of the landscape than...
Article
Full-text available
Geological, geomorphological and soil maps provide important information on the substrate as well as on the past and present physical landscape. For the intensely studied Netherlands coastal plain and Rhine–Meuse delta, many such map datasets have been compiled over the last two centuries.

The dynamic regional history of coeval loss of peat...
Conference Paper
Full-text available
Current models that project sea-level rise beyond 2100 have large uncertainties because recent observation encompass a too limited range of climate variability to provide robust tests against which to simulate future changes. It is crucial to turn to the geological record where there are large-scale changes in climate, but the current interglacial...
