Abstract Modern fluvial meander plains exhibit complex planform transformations in response to meander‐bend expansion, downstream migration and rotation. These exert a fundamental control on lithology reservoir properties, yet their stratigraphic record has been poorly evaluated ancient examples due the lack of extensive three‐dimensional exposures. Here, unique exhumed plain exposed north Scarborough (Yorkshire, UK ) is analysed terms architecture morphodynamics, with aim developing...
Significance Meandering tidal channel networks play a central role in the ecomorphodynamic evolution of landscapes they cut through. Despite their ubiquitous presence and relevance to sedimentary landscape features, few observations tidal-meander exist, we lack full understanding governing processes. Field analyses show that meanders, traditionally viewed as stable display modes migration rates per unit width quite similar those characterizing fluvial counterparts, with important...
Abstract Salt marshes are crucially important ecosystems at the boundary between land and sea, that experiencing significant losses worldwide mainly dictated by erosion of their margins. Improving our understanding mechanisms controlling marsh edge is a key step to address conservation issues salt‐marsh response changes in environmental forcing. Here we have employed complete, coupled Wind‐Wave Tidal Model (WWTM) analyse temporal evolution wave field, particular mean wave‐power density,...
Stabilization of riverbanks by vegetation has long been considered necessary to sustain single-thread meandering rivers. However, observation active in modern barren landscapes challenges this assumption. Here, we investigate a globally distributed set rivers with varying riparian densities, using satellite imagery and statistical analyses meander-form descriptors migration rates. We show that enhances the coefficient proportionality between channel curvature rates at low curvatures, effect...
Abstract The mode of channel‐bend transformation (i.e. expansion, translation, rotation or a combination thereof) has direct bearing on the dimensions, shape, bedding architecture and connectivity point‐bar sandstone bodies within fluvial meander belt, but is generally difficult to recognize in vertical outcrops. This study demonstrates how bend relative rate channel‐floor aggradation can be deciphered from longitudinal outcrop sections aligned parallel meander‐belt axis, as crucial...
Abstract Gilbert‐type deltas are sensitive recorders of short‐term base‐level changes, but the delta‐front record a rise tends to be erased by fluvial erosion during subsequent fall, which renders bulk changes difficult decipher from deposits. The present detailed study three large Pleistocene uplifted on southern coast Gulf Corinth, Greece, indicates genetic link between morphodynamic responses and delta‐slope sedimentation processes. Sigmoidal delta‐brink architecture signifies is...
Abstract Meandering channels extensively dissect fluvial and tidal landscapes, critically controlling their morphodynamic evolution sedimentary architecture. In spite of an apparently striking dissimilarity the governing processes, planform dimensions meanders consistently scale to local channel width, previous studies were unable identify quantitative planimetric differences between these landforms. Here we use satellite imagery, measurements meandering patterns, different statistical...
Abstract Sinuous channels wandering through coastal wetlands have been thought to lack lateral‐migration features like meander cutoffs and oxbows, spurring the broad interpretation that tidal fluvial meanders differ morphodynamically. Motivated by recent work showing similarities in planform dynamics between meandering channels, we analyzed neck from diverse environments worldwide, show are widespread. Their perceived paucity stems pronounced channel density hydrological connectivity...
Abstract This paper focuses on Holocene deposits of the Firenze alluvial plain (Northern Apennines, Italy) and deals with sedimentary features chute channels draining down‐river edges meander neck formed by 70 to 100 m wide 1 1·5 deep sinuous channels. Two main types have been recognized. Type is represented 3 6 0·5 straight filled mud aggregates overlying a basal gravel lag made reworked caliches. These drained point bar top during floods, are thought initiated as small rills when shallow...
Abstract Results of a detailed sedimentological study the mid-Pleistocene Gilbert-type Ilias delta at southern coast Corinth Rift, Greece, are reported. The indicates that development turbidite-dominated facies assemblage (TFA) foreset deposits is associated with an oblique delta-brink geometry, which signifies deficit delta-front accommodation due to falling or stable base level. A debrite-dominated (DFA) forms when level rising and geometry becomes sigmoidal, signifying increase in...
Proterozoic rivers flowed through barren landscapes, and lacked interactions with macroscopic organisms. It is widely held that, in the absence of vegetation, fluvial systems featured barely entrenched channels that promptly widened over floodplains during floods. This hypothesis has never been tested because an enduring lack Precambrian fluvial-channel morphometric data. Here we show, remote sensing outcrop sedimentology, deep were developed Proterozoic, parameters for large might have...
Abstract The planform evolution of tidal meanders is driven by interactions between channel morphology and periodically reversing flows, which feed back into the development erosional depositional patterns. However, paucity quantitative data has so far undermined detailed analyses about geomorphic effects flows within meanders. Here we aim to bond morphodynamic with structure three‐dimensional flow that shapes them. By means an acoustic Doppler current profiler, have surveyed fields over...
Abstract River meandering controls the age of floodplains through its characteristic paces growth and eventual cutoff channel bends, forming oxbows. Hence, floodplain‐age distributions should reflect a river's size migration rate. This hypothesis has been previously tested in numerical simulations, yet without systematic comparisons with natural systems. Here we analyze oxbow spacing timescales bend evolution abandonment numerically simulated meander belts. In both cases, saturated state is...
Abstract Bend cutoff is a fundamental process shaping meandering rivers. Despite the widely accepted differentiation between neck and chute cutoffs, significant knowledge gap persists regarding factors responsible for occurrence of each regime specific conditions triggering regime. Here, we used field photogrammetric data derived from global set 22 rivers, stretching more than 5500 km in total river length, to disentangle controlling behind We found that whether forms rather meander depends...
Abstract The widespread distribution of tidal creeks and channels that undertake meandering behaviour in modern coasts contrasts with their limited documentation the fossil record, where point‐bar elements arising from interaction between a mix both fluvial currents are mainly documented. sedimentary products channel‐bend evolution relatively poorly known, few studies have focused previously on specific facies models for point bars present settings. This study improves understanding channel...
Abstract Assessments of depositional architecture and paleodrainage in planform are increasingly recognized as critical for the reconstruction ancient fluvial morphodynamics; however, planview exposures ancient, undeformed meandering-fluvial deposits scattered, exceptional occurrences such exhumed meander plain Scalby Formation (Yorkshire, UK) deserve particular attention. Here we specifically focus on style morphodynamics downstream-migrating point bars, providing parallels with modern...
Abstract Tidal channels form the pathways for tidal currents to propagate and distribute clastic sediments nutrients, thus providing a primary control on tidal‐landscape ecomorphodynamics. Most in both estuarine lagoonal environments have tendency meander, yet very few studies exist that investigate full spectrum of processes controlling meander morpho‐sedimentary evolution. The Venice Lagoon (Italy) offers unique opportunity shed light this topic, because long record morphological...
