Establishing an irrigation management plan of sustainable groundwater based on spatial variability of water quality and quantity

摘要: Summary Conditions of water quality and quantity are two key factors impacting groundwater utilization for irrigation. To obtain pristine reduce pumping impacts on aquifers, this study establishes an irrigation management plan sustainable in the Pingtung Plain Taiwan based spatial variability parameters. According to standard, multivariate indicator kriging (IK) was adopted estimate integration hydrochemical parameters groundwater. IK also used grade transmissivity fields representing capacity aquifers. Six risk categories recommended were spatially delineated combinations five levels determined by estimated probabilities. The analyzed results indicate that 54.4% aquifers extract belonging excellent optimal locations, where can be without dilution. ordinary regions, mixed with surface is appropriate use
