Accurate rainfall forecasting in watersheds is of indispensable importance for predicting streamflow and flash floods. This paper investigates the accuracy several technologies based on Wavelet Packet Decomposition (WPD) monthly forecasting. First, WPD decomposes observed data into subcomponents. Then, three data-based models, namely Back-propagation Neural Network (BPNN) model, group method handing (GMDH) autoregressive integrated moving average (ARIMA) are utilized to complete prediction...
In the past decade, more than 300 people have died per year on average due to mountain torrents in China. Mountain mostly occur ungauged small and medium-sized catchments, so it is difficult maintain high accuracy of flood prediction. order solve problem low simulation areas, this paper studies influence different methods parameter regionalization distributed hydrological model parameters hilly areas Hunan Province. According terrain, landform, soil land use characteristics each catchment,...
Abstract This article proposes a multi-head attention flood forecasting model (MHAFFM) that combines mechanism (MHAM) with multiple linear regression for forecasting. Compared to models based on Long Short-Term Memory (LSTM) neural networks, MHAFFM enables precise and stable multi-hour First, the utilizes characteristics of full-batch input data in solve problem oscillation prediction results existing models. Second, information is connected MHAM improve model's ability process interpret...
This study investigated the crack propagation law of expansive soil slopes under drying–wetting conditions and influence cracks on by conducting a large-scale indoor slope test subjected to cycles. The change in moisture content at different depths during cycles was monitored using sensor, variation drying process measured depth detector. slope’s surface were processed self-made binarization program, evolution mechanism analyzed. rainfall-induced fractured used obtain soils, analyze dry–wet...
Drawing upon the fundamental principles of mixture continuum and thermodynamics, planar S-wave incident model for layered unsaturated soil is formulated. Employing Helmholtz vector decomposition principle, wave field within analyzed using transfer matrix method, accounting influence thermal effects. An analytical solution obtained seismic response in under action effect. The results numerical analyses show that thermo-physical parameters such as relative heat solid, temperature, expansion...
With digital information technology based on limited data, disaster simulation review is an important guideline for analyzing mechanisms, planning post-disaster reconstruction, and improving defense capability. Taking the “7.20” flash flood in Wangzongdian river basin as a research area, hydrological-hydrodynamic model was established using measured data. The results showed that extreme rainstorm caused flooding mountainous areas collapse of subgrade water damming, high-level quickly flowed...
Summary The propagation characteristic of Rayleigh waves in a fluid‐saturated non‐homogeneous poroelastic half‐plane is addressed. Based on Biot's theory for media, which takes the inertia, fluid viscosity, mechanical coupling, compressibility solid grains, and into account, dispersion equations soils/rocks are established. By considering shear modulus skeleton variation with depth exponentially, small parameter, reflects relative change modulus, introduced. asymptotic solution equation...
SUMMARY Based on the propagation theory of elastic waves in three-phase frozen poroelastic media and single-phase media, energy transmission problem a plane harmonic P-wave incident at planar interface between medium is studied. According to boundary conditions interface, analytical expressions reflection coefficients ratios transmitted reflected are derived. The relationship angle, frequency wave, cementation parameters, porosity, saturation contact parameters investigated. results show...
