Integrated Consideration of Quality and Quantity to Determine Regional Groundwater Monitoring Site in South Korea

As the purpose of the regional groundwater monitoring station is to observe both quality and the levels of groundwater in South Korea, it is most efficient and economical to establish the monitoring station at a site able to observe these two items simultaneously. A weighting and ranking method using GIS technology was used for the development of a site selection model. This model uses a land-use type of target area with regard to quality and a lineament length density with regard to quantity. It was shown that this weighting and ranking method is appropriate and convenient for selecting a monitoring site because it proposes the relative importance and priority of groundwater monitoring for each site. Additionally, if this method is used together with the other method like an analytical hierarchy process (AHP) method, the optimal and specific monitoring site can be easily selected and the additional field investigation can be reduced.
