Abstract The world’s largest hydropower dam, the Three Gorges Dam (TGD), spans upper Yangtze River in China, creating a 660-km long and 1.1-km wide reservoir upstream. Several recent studies reported considerable decline sediment load of Lowermost (LmYR) rapid erosion subaqueous delta river mouth after closure TGD 2003. However, it is unknown if construction has also affected channel bed formation LmYR. In this study, we compared bathymetric data last 565 kilometers River’s between 1998...
Abstract Alluvial rivers are shaped by interactions of flow and sediment transport. Their lower reaches to the world's oceans highly dynamic, often presenting engineering management challenges. Here we analyzed over 6,000 single‐beam cross‐sectional measurements surveyed in 1992, 2004, 2013 last 500‐km reach engineered Mississippi River, also known as lowermost River or LmMR, starting from river's Gulf outlet its avulsion into Atchafalaya River. We applied inverse distance weighted...
A recent study reported considerable sediment trapping by three large channel bars downstream 18–28 km of the Mississippi–Atchafalaya River diversion (commonly known as Old Control Structure, ORCS) during 2011 Mississippi flood. In this study, we analyzed 3-decadal morphological changes 10-km river and to elucidate long-term effects engineering including diversion, revetment dike constructions. Satellite images captured between 1985 2015 in approximate 5-year intervals were selected estimate...
Water-land ecotone is a core area of wetlands which play an important role in ecological function. The information vegetation type on the water-land for detecting health wetland, and its protection. Seasonal flooding key factor controlling environment ecotone. Even preventing direct detection flooded with satellites, seasonal has effects distribution plants, may provide potential classification satellites. Therefore, study induces index mapping We applied Sentinel-1 Sentinel-2 images to map...
The formation of channel bars has been recognized as the most significant sediment response to highly trained Mississippi River (MR). However, no quantitative study exists on dynamics emerged and associated accumulation in last 500-kilometer reach MR from Gulf Mexico outlet, also known lowermost River. Such knowledge is especially critical for riverine management impede coastal land loss Delta. In this study, we utilized a series satellite images taken August 2010 January 2012 assess changes...
Background: The first carpometacarpal (CMC) joint is a common site of osteoarthritis, with arthroplasty being procedure to provide pain relief and improve function low complications. However, little known about risk factors that may predispose patient for postoperative Methods: All CMC from 2005 2015 in the prospectively collected American College Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database were identified. Bivariate testing multiple logistic regressions...
River confluences are important nodes for downstream sediment transport and geomorphological development. Previous studies have established the knowledge that under natural conditions, river confluence zones experience channel scour followed with middle bar Less care is however given to intensity of a zone man-controlled such as discharge regulation levee confinement. In general, our about long-term bed evolution large alluvial limited. Here we conducted study focused on 69-km uppermost...
This paper introduces scour physics-informed neural networks (SPINNs), a hybrid physics-data-driven framework for bridge prediction using deep learning. SPINNs are developed based on historical monitoring data and integrate physics-based empirical equations into as supplementary loss components. We incorporated three architectures: LSTM, CNN, NLinear the base data-driven model. Despite varying performance across different models bridges, overall outperformed pure models. In some cases, SPINN...
By changing the alignment angle of spur dike, this study focused on evolution scour hole morphology in three alignments under clear-water conditions, including 3-D structure hole, 2-D profile morphological process and characteristics local bed shear stress. The results show that plane area volume both are power functions over time, which is similar to depth. Local includes stages: initial stage, development stage balance stage. stress presents successively: τb > τc, = τc < τc. Based...
Abstract Bed material transport at river bifurcations is crucial for channel stability and downstream geomorphic dynamics. However, measurements of bed large alluvial rivers are difficult to make, standard estimates based on the assumption proportional partitioning flow bedload may be erroneous. In this study, we employed a combined approach observed topographic change (erosion/deposition) predicted from one‐dimensional model investigate fluxes near engineering‐controlled...
Deltaic channels are significant landforms at the interface of sediment transfer from land to oceanic realms. Understanding dynamics these is urgent because delta processes sensitive climate change and adjustments in human activity. To obtain a better understanding morphological large deltaic channels, this study assessed evolution response mechanism South Channel Passage (SCSP) Yangtze Estuary between 1983 2018 using hydrology, multibeam echo sounding historical bathymetry datasets. Decadal...
Abstract Avulsions change river courses and transport water sediment to new channels impacting infrastructure, floodplain evolution, ecosystems. Abrupt avulsion events (occurring over days weeks) are potentially catastrophic society thus receive more attention than slow avulsions, which develop decades centuries can be challenging identify. Here, we examine gradual channel changes of the Peace‐Athabasca River Delta (PAD), Canada using in situ measurements 37 years Landsat satellite imagery....
In late 2023 the Surface Water and Ocean Topography (SWOT) satellite mission will release unprecedented high-resolution measurements of water surface elevation (WSE) slope (WSS) globally. SWOT's exciting Ka-band near-nadir wide-swath interferometric radar (InSAR) technology could transform studies hydrology, but remains highly experimental. We examine Airborne SWOT (AirSWOT) data acquired twice over Canada's Peace-Athabasca Delta (PAD), a large, low-gradient, ecologically important riverine...
Abstract Past research on fluvial dynamics at the confluence of two alluvial rivers has mainly focused downstream flow structure and bed scoring, often using laboratory experiments numerical modeling. Little is investigated about yearly episodic mouth bars that can affect morphology field measurements. In this study, we analyzed migration a bar free meandering rivers, Amite Comite Rivers in coastal Louisiana, USA from 2002 to 2017. Remote sensing images were utilized investigate decade‐long...

Abstract Artificial river bifurcations have been widely created for different purposes. Yet, long‐term dynamics in the bifurcated channels and natural downstream of artificial bifurcation nodes are not well investigated. Herein, we employed an approach combining three decades (1977–2006) bathymetric survey records, geographic information system (GIS) application, bed material transport modeling to investigate riverbed artificially channel Atchafalaya River, largest distributary Mississippi...
