Abstract
The basic elements of groundwater planning, monitoring, and management is groundwater hydro-informatics. A well-planned network of groundwater monitoring stations can provide accurate and reliable, regional characteristics of groundwater information of the establishment of groundwater monitoring networks stations typically include topography, thickness and groundwater aquifer parameters and other factors, many factors will affect to the groundwater monitoring network for the location and density.
In this study, it proposed a geostatistic approach for underground water monitoring well network design. It was applying hydraulic head as the input data to obtain the spatial structure of the study area, Choushui river basin. In order to measure the uncertainty of the candidate wells, Kriging Variance is proposed to be the index in this study. First, deciding which monitoring wells should be removed from the original network due to its bad spatial location by using the Control –area algorithm. A sequential network design approach decides which candidate well should be added into the groundwater monitoring network. The result shows that 10 of 46 wells removed from the second layer,10 of 42 wells removed from the third layer, and 20 wells was suggested to add into the groundwater monitoring well network in the fourth layer.
