ABSTRACT Floods are major natural disasters that present considerable challenges to socioeconomic and ecological systems. Flash floods highly nonlinear exhibit rapid spatiotemporal variability. Existing methods struggle capture these features, leading suboptimal long‐term peak flood prediction accuracy. This study proposes a hierarchical model based on clustering enhance forecasting accuracy in the Heshengxi watershed. We employ STGCN GWN models with attention mechanism. Enhanced loss...
This study evaluated multiple aspects of flood risks and effects on the Cinan Feizuo protection area in Huaihe River basin. Flooding remains a leading problem for infrastructure, especially urban, residential areas region. Effective modeling urbanized floodplains is challenging, but MIKE (ID-2D) paramount analyzing quantifying risk vulnerable The Saint-Venant equation one-dimensional (1D) 11 model were used to understand dynamics River, two-dimensional (2D) 21 was applied assess area. finite...
Abstract Storm floods occur frequently and have complex characteristics in arid mountainous areas, which for a long time has been weak link flood forecasting. The application of an artificial intelligent model physically‐based hydrological some limitations on forecasting areas with scarce data. In this article, the ANN Muskingum‐Cunge method are combined to propose networking (FFIN model) data, BR‐ANN is used forecast catchment sub‐basin runoff while General Regression Neural Network carry...
In this study, the riverbank inundation caused by moderate frequent flooding events (with recurrence periods of less than 20 years), along with increasingly serious hazards backward flows in dike-through drainage ditches Ningxia Reach upper Yellow River (NRYR), were investigated. Then, a comprehensive method for hazard assessment floodplains and NRYR was proposed, which fully integrated geographical information systems (GISs), remote sensing (RS), digital elevation model (DEM), as well river...
Recently, construction of many large-scale water conservancy projects, as well the vegetation protection and restoration projects in upper reaches Yellow River, have led to serious changes inflow processes, sediment scour silting situation Ningxia section River (NSYR). This study explored relationship between scouring law sediment-laden rivers equilibrium fluvial facies NSYR. The double cumulative curves annual amounts incoming Qingtongxia–Shizuishan were then established. It has been...
The identification of the characteristics short time rainstorms in urban areas is a difficult problem. traditional rainfall definition methods, using graph or GIS map, respectively reflect temporal spatial variations process, but do not regard as one complete process including its and dimension. In this paper, we present an approach to define typical modes from dimensions. Firstly, independent processes are divided based on continuous monitoring data multiple stations. Subsequently,...

Abstract. More than 10 high-speed railway routes with top speeds of 300 km h−1 are expected to be operational from Beijing by the year 2020. However, safety these is affected occurrence land subsidence. This paper focuses on Beijing–Tianjin Intercity High-Speed Railway (BTR), first in China, analyze analyzing both regional subsidence and local differential caused groundwater drawing. The construction stratum mainly composed cohesive soil, BTR has a maximum accumulative > 800 mm rate 80...
Abstract The Ningxia reach of the Yellow River (NRYR) is wide and shallow, instability damages are likely to occur at its vulnerable zone. In this study, based on one‐dimensional hydro‐sediment dynamics, two‐dimensional dynamics zone stability analysis model, a coupled model was established analyze scouring risk zones in NRYR during flood season. Considering morphological change bank slope caused by flow erosion, seepage typical spur dyke protection embankment under water level fluctuation...
Abstract Natural streamflow series usually exhibit a power law tail with magnitude–frequency relationship; however, it is not known how the distribution of daily varies under influence climate change and human activities. Based on annual Toudaoguai, Longmen, Sanmenxia, Huayuankou, Gaocun, Lijin stations located in Yellow River China, Mann–Kendall Mann–Whitney–Pettitt methods were used to identify change-points. Thereafter, distributions before after abrupt changes studied based two-parameter...
