MODELLING GROUNDWATER SPATIO-TEMPORAL VARIABILITY FROM WATER TABLE MONITORING DATA USING COVARIANCE FUNCTIONS

Abstract

Monitoring data are particularly interesting when analysing processes characteristics because can reveal not only temporal patterns but also spatial distributions and variation over time if collected in a geospatial network. Character and causes of variability can be explored from spatial and temporal correlations and allow to predict values at points from neighbouring observations. Spatio-temporal (ST) interpolation allows making predictions in between observation times and can potentially provide more accurate predictions than spatial interpolation because observations taken at other times can be included. This procedure requires covariance model capable to join spatial, temporal and spatiotemporal dependence structures, for instance represented as variograms. Recent developments in the implementation of these methods allowed that a whole family of theoretical covariance models was available to several natural phenomena applications. The aim of this project is to verify the applicability of ST geostatistics methods based on covariance models to water table depths monitoring data. Data from Bauru Aquifer System collected at 65 locations in the Santa Barbara Ecological Station/SP with a monthly frequency from September 2014 until the present date will be tested for this target. ST variograms can reveal information about spatial and temporal dependence, based on groundwater oscillation process. These results are important information for groundwater management and planning, monitoring strategies and remediation plans. (AU)
