Meandering rivers are a ubiquitous feature worldwide, exhibiting an extraordinary variety of planform patterns. These patterns, from widely observed point bars to alternating bend widening and narrowing, provide compelling evidence pulsed lateral migration meandering rivers. While these rhythmic migrations have recently been tied intermittent bank collapses, their morphological impacts over large temporal spatial scales remains largely unexplored. Here we investigate globally distributed set...
Abstract We set up a laboratory experiment to reproduce flow‐induced bank erosion and collapse study the role of height ( H b ) near‐bank water depth w on stability. Five experiments were conducted in plexiglass‐walled soil tank, using silt collected from natural tidal channel banks D 50 = 75 μm). During each experiment, was subject steady uniform flow. measured variations total stress, pore pressure (when negative, called matric suction), content inside flow velocity suspended‐sediment...
Abstract We develop a process‐based model to simulate the geomorphodynamic evolution of tidal channels, considering hydrodynamics, flow‐induced bank erosion, gravity‐induced collapse, and sediment dynamics. A stress‐deformation analysis Mohr‐Coulomb criterion, calibrated through previous laboratory experiments, are included in simulating collapse. Results show that collapsed soil plays primary role dynamics retreat. For collapse with small height, tensile failure middle (Stage I), on top...
Abstract Parallel tidal channel systems, characterized by commonly cross-shore orientation and regular spacing, represent a distinct class of networks in coastal environments worldwide. Intriguingly, these oriented systems can develop dominated alongshore currents, for which the mechanisms remain elusive. Here, we combine remote sensing imagery analysis morphodynamic simulations to demonstrate that deflection currents at transitions bed elevation determines characteristic parallel channels....
Coastal tidal flats provide valuable ecosystems, but are highly sensitive to dynamics, sea-level rise, and human activities. Tidal inundation depth frequency known affect flat morphodynamics. However, the causes, processes extent remain uncertain, particularly given associated changes in sediment availability. In this study, we monitored hydrodynamics, transport, morphological on two northern southern parts of Yellow River Delta, with contrasting regimes. The data showed that longer periods...
Abstract The radial sand ridges (denoted as “RSRs” hereafter) in the Southern Yellow Sea, China, are morphologically striking because of remarkable size and planar orientation, standing out a unique coastal geomorphology among worldwide ridge systems. formation this giant fan‐shaped geomorphic feature requires delicate conditions awaits in‐depth investigation. Using an idealized morphodynamic model, study unravels governing factors for large‐scale RSRs, comparison with other types systems...
Abstract Reclamation of low‐lying tidal flats and floodplains adjacent to present shorelines has been implemented worldwide for both coastal defense development. While it is technically feasible monitor the short‐term impact flat embankments, challenging identify long‐term cumulative morphodynamic impact, particularly considering centennial sea‐level rise (SLR). In this study, we construct a process‐based hydro‐morphodynamic model schematized basin examine its evolution under combined...
We set up a two‐dimensional modeling framework to explore the development and equilibrium configuration of tidal channel. consider two types morphodynamic systems coupling different flow sedimentation models, study feedback mechanisms controlling morphodynamics channels. The simulations indicate that channel first experiences pseudo state, then diverges from it, finally approaches dynamic equilibrium. reason for this behavior is demonstrated analytically using linear perturbation analysis....
Abstract The survival of salt marshes, especially facing future sea‐level rise, requires sediment supply. Sediment can be supplied to marshes via two routes: through marsh creeks and over edges. However, the conditions tides waves that facilitate import these routes remain unclear. To understand when how is imported into 2‐month measurements were conducted monitor tides, waves, suspended concentration (SSC) in Paulina Saltmarsh, a meso‐macrotidal system. results show creek tends during neap...
Branching networks are key elements in natural landscapes and have attracted sustained research interest across the geosciences numerous intersecting fields. The prevailing consensus has long held that branching optimized exhibit fractal properties adhering to power-law scaling relationships. However, tidal coastal wetlands mudflats defy conventional descriptions, presenting a longstanding enigma. Here we show observed atypical represents universal deviation from an ideal network capable of...
Abstract The morphodynamic responses of tidal networks to anthropogenic reclamation and de-reclamation projects are investigated through a three-stage numerical simulation. In the first stage, natural development is modelled in an open coast without any interventions. At beginning second parts computational domain enclosed by sea dikes, which represents implementation project. These dikes removed or opened third stage simulate recovery after de-reclamation. Each was set last 100 years. model...
Abstract The description of the geomorphic characteristics in power law forms has been subject research, over past 70 years, and become cornerstone regime theory. However, just why functions should represent such relationships remains poorly understood. Hence, differences values exponents observed for different river systems remain largely unexplained. To address this issue, we derived generic without postulating any discharge. theoretical approach accurately captures systematic variations...
