Erosion of beach land and villages will be resulted from instability of Yellow River beach strand, even embankment will be burst, so it has important practice to analyze stability of Yellow River beach strand and its sensibility to influencing factors. The main factors that much influence the stability of beach strand are selected as cohesion C, water head and slope angle aand the different analysis...
As an important water resource, groundwater quality is connected with people life and economical sustainable development. Shallow groundwater is subject to the anthropogenic influence because of shallow burial depth. In 19 monitoring indexes 15indexes reach the Chinese standard and the over standard programs are total hardness, nitrate nitrogen, total dissolved solids and nitrite nitrogen. The quality...
Although there are many methods or models widely applied to evaluate water resources carrying capacity, the evaluation result is qualitative not quantitative. In order to quantificationally evaluate groundwater carrying capacity in irrigation district, multi-objective evaluation model of groundwater carrying capacity was established, which includes four objectives, i.e., GDP, grain yield, population...
Introducing chaos theory into the floodwater disaster resources field, the forecasting model for the inundated area of flood disaster was brought forward integrating reconstruction of phase space and neural network. One dimension inundated area series is developed many dimension inundated area series with reconstruction of phase space, and multi- dimension series include the ergodic information, so...
Water resources system is complicated nonlinear systems in Henan plain, that is operated by nature-man duality driving force and divided into 4 subsystems: precipitate water, surface water, shallow groundwater, and deep underground water. The analysis principle of dynamics characteristics and modeling of water resources system is given and the nonlinear dynamics characteristics of water resources...
The mine water system is a nonlinear and dynamic system influenced by such factors as hydrological and geological conditions. Although neural network model can effectively solve the nonlinear problems, it's difficult to obtain the satisfying results by direct prediction for the time series of water yield of mine because of chaotic characteristics in the system. In order to discover the nonlinear structure...
