In particular, the braided channel in the wide valley section in the Source Region of the Yangtze River (SRYR) has undergone drastic adjustments due to recent summer floods and further adjustments are expected in the future as climate change continues. Nonetheless, a lack of a quantitative description of the phenomenon persists. In order to unravel morphodynamic processes of a braided river under different flood flow discharges, a two-dimensional morphodynamic model was established using Delft3D to simulate the local braided channel in the Tuotuo River based on field observations and remote sensing images in the SRYR. The data of 1, 2, 5, and 10-yr flood hydrographs from 1985 to 2020 were obtained, using the hydrological data at the Tuotuohe Gauging Station. Specifically, two groups of actual flood hydrographs were used to simulate the hydrodynamic and riverbed adjustment of the braided channel reach. The following findings were revealed: (i) increases in discharge cause increases of the water level, and thus the flood flow erode and submerge the sandbars. During a flood, the previous branches are replaced by new branches and the braided channel shows a significantly different configuration after the flood. (ii) With the increase of the flood discharge, the amount of sediment erosion and deposition in the braided channels escalates. Specifically, the sediment erosion and deposition of the 10-yr flood will increase by 3.1 times and 4.7 times, respectively, in comparison with the 1-yr flood. (iii) When the discharge is greater than 180 m³/s, the braiding intensity in the wide valley section (&gt;1.2 km) has a significant decreasing trend with the increase in the flood flow. When the discharge is less than 180 m³/s, the correlation between the braiding intensity and flood flow is not significant in the wide reach. (iv) The braiding intensity of the wide reach as flood frequency increases from the 1- to 2-yr events increases by 14.3%, 11.6%, respectively, and decreases for the 5- to 10-yr events by 3.2% and 10.8%, respectively. In the narrow reach, the increases are 25.5% and 11.2%, for the 1- and 2-yr events, respectively, and the decreases are 25.0% and 53.3% for the 5- and 10-yr events, respectively. The parabolic shape of the correlation between the braided intensity and flood discharge increases first, reaches a peak, and then decreases. Overall, the current study contributes to the understanding of the impact of gradually increasing flood discharge on the morphodynamics of braided rivers in the QTP.</div></div>","PeriodicalId":50290,"journal":{"name":"International Journal of Sediment Research","volume":"40 3","pages":"Pages 439-453"},"PeriodicalIF":3.5,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a series of specially designed flume tests are performed to simulate the self-cleaning process. The flow rate, relative opening, bed-slope angle, and number of openings are considered. The erosion process, topographic characteristics, and relative erosion depth are analyzed to gain insight into the self-cleaning details. The current results reveal that when the boulders jamming the openings are removed, erosion occurs in three stages (downcutting, headward erosion, and lateral erosion). Conversely, when the blockage remains stable, only surface armoring occurs. Furthermore, after the self-cleaning process reaches a quasiequilibrium state, the topographic features are summarized, and the differences in the maximum erosion depth at the opening are analyzed for different experimental conditions. This paper proposes a critical criterion (<em>F</em>) for the self-cleaning of slit dams on the basis of dimensional analysis. The critical criterion takes into account the interactions of three parameters (Froude number, relative opening, and opening rate) and can be conveniently applied to existing slit dams. When <em>F</em> is less than 0.25, the opening remains blocked, and only surface armoring occurs; when <em>F</em> is between 0.25 and 0.38, the blockage may be removed; and when <em>F</em> is greater than 0.38, self-cleaning leads to massive erosion, and the blockage is removed. Therefore, the proposed critical criterion can help design the opening dimensions of a slit dam, restoring its storage capacity. Finally, the positive effect of self-cleaning on restoring the storage capacity of slit dams is discussed.</div></div>","PeriodicalId":50290,"journal":{"name":"International Journal of Sediment Research","volume":"40 3","pages":"Pages 454-465"},"PeriodicalIF":3.5,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trigonal diagram shows that most of the lagoon sub-bottom deposits lie in the fine-grained tail. Silt is dominant within the Holocene fluvial-estuarine, estuarine-transitional, and shallow marine deposits. Sand fractions (&gt; 76%) are distributed in the coastal barrier and in a few fluvial-estuarine intervals.

Diatom species recovered from sediment cores have distinctive capacities for living under high marine, freshwater, and terrestrial conditions. Each quadrant of the PCA reflects the adaptation of species to particular depositional conditions during the Late Pleistocene and Holocene. Allochthonous taxa provide valuable ecological information about adjacent environments in the coastal area, offering insight into the paleogeography of the study area.

Bedload motion on a movable flatbed causes additional energy loss and increases hydraulic roughness. Several theoretical and empirical predictors for characterizing this phenomenon have been proposed, but the accuracy and physical basis of these models should be improved. In this study, the total energy dissipation rate is separated into two components: the energy dissipation rate due to grain drag and the additional energy dissipation rate due to bedload motion. Following the energy dissipation rate balance equation, a new predictor was proposed for movable flatbed flows. The water temperature was empirically coupled with the fluid viscosity and its associated physical variables. A new empirical relation between two dimensionless flow‒sediment combination variables was established to demarcate the various bedform transitions induced by the water temperature. The new predictor was compared with other predictors, and the prediction results were compared to the measured data. The error metric showed that the new predictor provided the highest accuracy, with ∼88.5% of the 826 data points falling within the ±30% error band. The new predictor suggested that the additional drag is nonlinearly proportional to the grain drag, and the scale factor between these two parameters is related to five flow‒sediment variables. In addition, the ability of the new predictor to quantify water temperature effects was examined. The predicted resistance exhibited three change modes with increasing water temperature, and the results suitably agreed with the measurements. The effect of the water temperature on the resistance of a movable flatbed is jointly controlled by the suspension number and roughness Reynolds number.

However, the fundamental mechanisms behind the formation and development of bedforms under varying flow conditions, the interconnection between sediment particle movement and bed morphology development, as well as the influence of bedforms on flow and sediment transport, are still not well understood. In the current study, the moveable bed load transport flume experiments under different flow conditions were done, and the development processes of two-dimensional and three-dimensional dunes formed under different flow intensities were simulated. The detailed structure of the bedforms was measured by laser scanning technology, the characteristics of the bedforms were analyzed in detail, and the relations between the formation of the bedforms and the movement of sediment particles are discussed. The results found that the correlation coefficients of the longitudinal profile curve can serve as a quick reference for distinguishing two-dimensional and three-dimensional dunes. When the crestline ratio is used as the criterion for two-dimensional and three-dimensional dunes, the relative amplitude of the dune crestline and the included angle with the flow direction should also be comprehensively considered. The lee side angles of dunes calculated using the triangle generalization method and local section tangent method are compared and show that the values obtained by the former method are only about half of that of the latter. It is also found that the lee side angles of dunes are related to the dune height. The superimposed dunes generally exist in the downstream area of the stoss side of the dunes. The local bed slopes on the stoss side of the dunes show reverse slopes. The superimposed dunes improve the local bed height and further increase the reverse slope degree of the stoss side. A streamwise ridge is an important form located in the upstream area of the dunes stoss side, and they are symmetrically distributed on both sides. Multiple streamwise ridges divide the stoss side of the dunes into relatively independent movement areas, restricting the movement of sediment particles to specific regions.
