Groundwater Resource Management Model Based on Digital Signal Processing (DSP) Technique——Case Study of a Certain Water Source Place in Northwest China
【摘要】 根据地下水资源管理模型响应矩阵法的建模思想,一般的二维承压含水层系统可分解为两个承压含水层子系统,一个为由人工干扰作用下的,另一个为由天然补径排条件作用下的.本文基于数字信号处理技术和方法的基本理论,证明了前者为线性时不变(LTI,LinearTimeIn-variability)系统,并应用LTI系统响应特征的卷积表示法,论述了将地下水流离散系统通过响应矩阵与规划管理模型进行耦合的方法.最后,建立某水源地规划管理模型,计算结果表明数字信号处理技术可应用于地下水资源优化配置和管理.
【Abstract】 Generally, according to the idea of responding matrix method among groundwater resource management models, a two-dimension (2D) confined aquifer system can be divided into two subsystem which are the one formed by artificial activities and the one formed under natural supplying/draining conditions. The former had been theoretically proven a Linear Time Invariability (LTI) system based on the Digital Signal Processing(DSP) technique in this article. Meanwhile, by using the convolution integral expression which can reflect LTI system’s responding characteristics, the method of coupling the discrete groundwater system with the management model through the responding matrix is discussed. A management model of water resources in a certain area has been established. The calculated resuts using the model can be applied in optimal scheme and management.
