Lag monitoring model for groundwater table around reservoir
Construction of lag monitoring model will help master the change rule of groundwater table around reservoir and ensure production and life safety.In order to describe the change process of groundwater table accurately,the hysteresis effect must be taken into account in monitoring model because the groundwater table lags behind such environmental parameters as water level and precipitation.The standard normal function was put forward to act as the hysteresis function of reservoir level and precipitation in the paper.A monitoring model for groundwater table is formed based on the the hysteresis function.Lastly,the monitoring model was used to analyze the groundwater table around a reservoir.The case study showed that such monitoring model based on hysteresis function not only have the benefit of obtaining the precise delay parameters,but also have higher computational accuracy.
