“…tides, storms, sea-level rise). Studies focusing on tectonics in overbank sediments of alluvial valley floodplains (such as the New Madrid Seismic Zone (NMSZ) in the Mississippi valley; Guccione et al, 2002) or deltaic floodbasins (such as this study) are still rare. Yet, deltaic systems have low-gradient reaches, and low-gradient channels are believed to be most sensitive to subtle neotectonic deformation (Holbrook & Schumm, 1999), and their Holocene records, particularly in the floodbasins, are relatively continuous and complete.…”

“…For example, in the New Madrid Seismic Zone a crevasse splay has been documented that preferentially developed in the down-warped area directly north-east of the Lake County Uplift (Guccione et al, 2002), and within the Okavango Fan panhandle-region, the transition from meandering to avulsive anastomozing reaches has been related to the activity of the upstream fault-zone of a subsurface graben (Smith et al, 1997). The present study shows that across active normal faults, rivers in their deltaic reaches experience similar tectonic controls to those identified in alluvial Differential subsidence in fluvio-deltaic floodbasin deposits 317…”

In the central Netherlands, the Rhine follows a course imposed by Late Quaternary glaciation, forcing it to cross several tectonic blocks of the Roer Valley Graben system before entering the south-eastern North Sea Basin. Holocene sealevel rise resulted in the formation of a coastal prism (Holocene Rhine-Meuse delta). Across the Peel Boundary Fault-zone (PBF) in the central delta, differences in subsidence between the downstream Roer Valley Graben and its upstream shoulder influenced fluvial deposition. This study examines the sedimentary response upstream and downstream of the PBF and uses that to quantify differential subsidence rates. The local identification and quantification of the subsidence component within deltaic relative base-level rise may serve to determine to what extent coastal prism aggradation and resulting architecture are controlled by downstream sea-level rise, local tectonics and discharge coming from upstream.A floodbasin-section shows both syn-depositional and post-depositional tectonic effects in the Late-glacial to Holocene (marine oxygen isotope stages 2 and 1) sedimentary record, and reveals an active fault of the Peel Boundary Fault-zone. Differential subsidence across the PBF is quantified for the Last Glacial Maximum subsurface (averaged rate c. 0.06 m kyr −1 over the past 15 kyr). The offset in Holocene basal peat yields a similar value (0.03-0.07 m kyr −1 , averaged over the past 7 kyr). Groundwater-level rise in the study area (as reconstructed from series of radiocarbon-dated basal peats) is used to quantify subsidence by comparison with relative sea-level rise at the river mouth. High rates of subsidence between 7000 and 5500 cal. yr BP together with syn-depositional sedimentary evidence suggest that the last major activity (palaeo-earthquakes) along this fault occurred in the middle Holocene. The timing of this and earlier fault activity may be related to the deglaciation and sea-level rise history. The results imply that early-middle Holocene deltaic back-filling should not be attributed solely to downstream relative sea-level rise dominating upstream controls, but that local differential subsidence is another independent control. Similar effects of differential subsidence in coastal prism sedimentary architecture can be expected in other coastal prisms.

“…A prime example includes subsidence and neotectonic controls, which slowly induce shallow warping of floodplain surfaces. Such influences result in small amounts of incremental change over short (e.g., annual) time-scales, but result in significant changes to the floodplain topography and drainage (e.g., Guccione et al 2002) over long time-scales. The importance of this is appreciated along the Red River of Manitoba (see chapter "Flooding, Structural Flood Control Measures, and Recent Geomorphic Research Along the Red River, Manitoba, Canada"), where subsidence of Pleistocene deposits influences the modern river valley gradient associated with the high flood frequency.…”

Geomorphic Approaches to Integrated Floodplain Management of Lowland Fluvial Systems in North America and Europe

Embanked floodplains are the status-quo where humans are a major component of the environment, especially across Europe and North America. Effective management of embanked rivers requires a comprehensive knowledge of past and present-day geomorphic processes, including sediment transport and channel and floodplain dynamics. Many approaches to management include activities and modifications which take into account past natural and human impacts and management decisions, resulting in a palimpsest of river and floodplain management. A synthesis of 12 diverse case studies provides evidence of the palimpsest in river-floodplain management, and illustrates four key roles for geomorphology in the design of effective management strategies, including (1) regional and longerterm context, (2) system evolution and past human impacts, (3) engineering design and management options, and (4), environmental and geomorphic restoration as an end-product. A review and comparison of heavily managed embanked rivers spanning a range of climatic and geomorphic provinces across North America and Europe illustrate the role of geomorphology in this palimpsest and its value to integrated management.
