High-speed water flow conditions can cause erosion of the bedrock in engineering areas. Due to lack accurate evaluation scour and rates, there has been a consumption manpower resources without achieving satisfactory outcomes. Therefore, studying scouring effects on is significant importance for maintaining sustainable development safety projects. Using prototype from Xiaonanhai site upper reaches Yangtze River, model test device was developed conduct anti-scour tests bedrock. The study...
Due to the inherent limitations in remote sensing image quality, seasonal variations, and radiometric inconsistencies, river extraction based on classification often results omissions. These challenges are particularly pronounced detection of narrow complex networks, where fine features frequently underrepresented, leading fragmented discontinuous water body extraction. To address these issues enhance both completeness accuracy identification, this study proposes an advanced optimization...
Abstract: Under the combined operation of upstream cascade reservoirs with Three Gorges Project as core and comprehensive impact climate change, water sediment conditions in middle lower reaches Yangtze River have undergone significant changes, which had a profound on evolution pattern river-lake system. This paper takes confluence reach Mainstream Dongting Lake research object. Through physical model(plane scale 1:400, vertical 1:100) experiments, process flow rule erosion deposition outlet...
The correlations between leaf traits of plants with floating leaves and the responses these to changes in water depth can be used explore ecological adaptation strategies aquatic plants. However, few studies have investigated covariation correlation petiole morphological indices along natural gradients. Three plots were established a gradient: plot I (shallow water, ranging from 0 20 cm), II (medium 40 III (deep level 60 cm). plant Nymphoides peltata (S. G. Gmel.) Kuntze was studied Qionghai...
After the construction of Three Gorges Dam (TGD) in China, downstream has been affected by reduction sediment discharge and regulation flow processes, which have resulted severe scouring changes hydrological regime. Consequently, spawning ground Chinese sturgeon distributed along Yichang reach could be affected. This study examined effects TGD on streamflow, load channel morphology based situ measured data. Results showed that, after impoundment TGD, at station decreased significantly,...
In this article, analysis has been made with regard to current situation of ecological revetment works and requirements river channels in the middle lower reaches Yangtze River, types etc. The development trend its application prospect are also discussed. indicates that, after impoundment Three Gorge Reservoir, erosion River will result severe like local channel adjustment bank collapse continuous weakening system. It is necessary keep on strengthening comprehensive control adopting future.
A prediction–correction solver is presented here for rapid simulation of free-surface flows in dendritic and looped river networks. Rather than solving a large global algebraic system over the entire domain networks, model solves subsystems subdomains branches two steps: prediction correction. With help method (PCM), partial linearization technique, semi-implicit method, Eulerian–Lagrangian (ELM), only needs to solve tridiagonal linear systems free any iteration. The new was tested using...
In order to understand the root morphology distribution and mechanical properties of typical herbaceous plants, evaluate ability soil reinforcement by plant roots, investigation, single tensile test in laboratory cohesion evaluation Wu-Waldron model were carried out on two local representative Kochia scoparia (L.) Schrad Artemisia sacrorum Ledeb. Loess Plateau China. The results showed that morphological indexes (root number, diameter, cross-sectional area, surface volume area ratio) plants...
A semi–implicit numerical model with a linear solver is proposed for the free-surface and pressurized mixed flows in hydraulic systems. It solves two flow regimes within unified formulation, much simpler than existing similar models flows. Using local linearization an Eulerian–Lagrangian method, new only needs to solve tridiagonal system (arising from velocity-pressure coupling) free of iterations. The tested using various types flows, where simulation results agree analytical solutions,...
As influenced by human activities, including high dam construction, soil and water conservation, sand mining in the upper reaches of rivers, amount sediment entering lower river decreases significantly. Human activities disturb natural balance between evolution as well movement induce new characteristics evolution. After construction operation Danjiangkou Reservoir Three Gorges Yangtze River (China), different degrees bend bypassing shoal cutting bends downstream dams are observed. The...
Because of special morphologies and complex runoff–tide interactions, the landward floodtide flows in Yangtze Estuary are observed to spill over from North South Branches, carrying a lot sediment. To quantitatively clarify spillover problem, two-dimensional numerical model using high-resolution channel-refined unstructured grid is developed for entire Datong river mouths (620 km) part East Sea. The ensures good description river-coast-ocean coupling, irregular boundaries, local regimes...
Laboratory experiments were conducted in a flume containing three types of artificial flexible submerged and emergent vegetation. Detailed measurements velocity sediment concentration the channel taken. The results showed that vegetation generates much greater resistance to flow significantly alters vertical distributions velocity, especially vegetated downstream regions. In comparison with non-vegetated case, turbulence kinetic energy Reynolds stresses regions higher, indicating strong...
