Climate change with extreme hydrological conditions, such as drought and flood, bring new challenges to seepage behavior the stability of earthfill dams. Taking a drought-stricken dam China an example, influence drought-flood cycles on is analyzed. This paper includes clay sample laboratory experiment unsteady finite element method simulation mentioned dam. Results show that severe causes cracks surface soil sample. Long-term deeper induces sharp increase suction pressure, indicating would...
Focusing on the sediment in Suyahu Reservoir (a typical plain reservoir Henan Province, China), concentrations of eutrophication-causing substances (TOC, TN and TP) heavy metal contamination (Zn, Pb, Cd, Cu, Cr, Ni, As Hg) were measured. Spatial distribution these contaminants resulting potential ecological risk investigated detail. The results indicated that concentrated sediment, with high south low north due to hydrodynamics. sediments polluted had an eutrophication problem average...
Bisphenol A (BPA) as an important industrial material has attracted substantial interests due to its environmental concerns. Here in dialysis membrane enclosed laccase catalysis (DMELC) strategy was adopted firstly degrade BPA. The feasibility and efficiency of DMELC (81.7% increase) for enhancing BPA degradation were demonstrated experimentally by comparing with the process without membranes. enhanced could be realized varying execution time, initial concentration, pH, temperature, running...
Most dam seepage safety analyses evaluate a stable field, infiltration line, and flow. However, under fluctuating drought-flood conditions, the soil surface becomes cracked, making it too complicated to conduct routine analysis. In this paper, characteristics of an inclined wall conditions were studied using large-scale physical model. The results show that after drought, permeability coefficient clay with low crack development was smaller than saturated permeability, but for cracked areas,...
The availability of massive amount dam safety monitoring data can make it difficult to analyze and characterize behavior. This article describes the use Cloud model transform quantitative into qualitative information. Each point returning is regarded as a cloud drop, parameters such expectation, entropy, hyper-entropy are obtained through backward generator represent operational state dam. points then treated vectors, similarity calculated using cosine value angle between them. coefficient...
Abstract Vulnerability to natural disasters falls into three categories: exposure, resistance, and resilience, where resilience mainly refers the capability of a pressure-bearing system recover by returning its initial state, that is, ability adapt disaster pressure. Resilience is major subject research on prevention mitigation. This focuses hydraulic structure from significant impacts typhoons. According load/unload response ratio theory, degree instability which nonlinear systems can be...
As crucial water conservancy projects, ship locks play a key role in flood control, shipping, resource allocation, and promoting regional economic development, making them an indispensable part of the modern transportation system. Utilizing satellite remote sensing for lock extraction can significantly reduce manual workload costs, assist daily dynamic maintenance hubs, provide more comprehensive data support construction management transport infrastructure. In this context, paper proposes...
Due to the effect of extreme environments, concrete dams face emerging challenges. Effect two typical earthquake and climate fluctuation, on dam was studied. Analysis dam, dealt mainly with seismic damage Shapai Tongkou hydropower stations obtain characteristics damages, thereby, propose measures for project rehabilitation. It is increase our knowledge objective laws enhance capability against risk. Taking low temperature event Xixi reservoir due anomaly example, systematically Through...
Flow data are key information for effective river management. In recent years, the UAV (Unmanned Aerial Vehicle) technology has been experiencing rapid development and exhibited unique advantages in field of ground surveying mapping. A advancement flow measurement involves use as an aerial platform acquiring water surface velocity distributions through Large Scale Particle Image Velocimetry (LSPIV). this paper, a uniform rotation first developed to mimic motion used study influences time...
Hydraulic model test is a very important method for research on large hydraulic structure under complex and extreme environments such as floods. To measure the topography around model, non-contact measurement with laser ultrasonic has been developed. Besides little disturbance to flow river bed, this makes it possible simultaneously quickly land underwater topography. The system composed of plane positioning mechanism, measuring devices ultrasonic, control data acquisition. accuracy ±1 mm,...
Multi-layer and multi-strand energy dissipation by hydraulic jump was adopt to discharge flood one giant hydropower station avoid the atomization effect. The safety of stilling basin structure critical for whole project, therefore, flow-induced vibration characteristics studied combined method including model test, numerical prediction field monitoring in this paper. Pulsation pressure on chute, bottom plate guide wall obtained from test. In frequent condition, main pulsation located at end...
As it's quite difficult to assess the importance of survivability impact factors dam safety information system with traditional methods, a new method is developed based on rough sets theory. Considering superiority theory knowledge mining, this takes useful from results assessment and makes an system. At last, example was given out for application method. It shows that helpful in reducing influence subjective factors. proves approach assessment.
Multimedia technology is widely used in various fields around the world. In recent years, it has also entered teaching classrooms, expounding theories and opinions with its powerful information sensory stimulation, enriching learning resources, affecting old models, bringing new ideas. Due to a strong sense of time, current affairs policy courses require multimedia simplify teaching. Current politics class an important part political education. It integrates at home abroad, such as politics,...
