SPACE-TIME ANALYSIS OF GROUNDWATER LEVEL VARIATION AROUND A DAM USING GEOSTATISTICS

The predictions of groundwater level around a dam which varies in the both space and time domain is very important for the dam maintenance. Geostatistical space-time models have been applied for modeling such spatiotemporal distributions in several scientific disciplines. In this paper, the new spatiotemporal random model and space-time cokriging are proposed. The model is characterized by the non-stationary as the random model in the temporal domain varies in the space domain. For the purpose of verifying its availability, the proposed method is applied to the data of an actual dam, consequently, it has proved to be very effective tool for estimation of spatio-temporal groundwater behavior through the some examinations.
