Applying Data Analysis Techniques to Groundwater Resources Management Modelling: a Case Study of Groundwater Sources “Zelenica” and “Gornje Polje” Near Loznica, Serbia

One of the data science techniques is the data analysis, based primarily on various techniques and methods application in order to acquire, analyze, interpret and eventually visualize the data. The aim of these techniques is the translation of the raw data into the useful information. In this study, a comprehensive data analysis of accessible geological and hydrogeological settings of terrain in zones near “Zelenica” and “Gornje Polje” springs (alluvium of river Drina) near Loznica, has been performed. The lithologic-technical profiles of observation and of water-sampling objects have been analysed, and results, obtained by geophysical methods, subsequently interpreted. Besides, the grain size analysis test, aquifer tests, precipitations monitoring and water-level of Drina river monitoring at specified precipitation-/water-gauge were performed too. Obtained results are used as a starting point for creating the hydrogeological model (and hydrodynamic one afterwards) of the research area. The main tools used were Microsoft Excel software (for data preparation and analyzing) and Modflow code (for hydrogeological and hydrodynamic models creation).
