Modelling of the behavior of ground water in clay ground

m MASTER'S THESIS ABSTRACT MODELLING OF THE BEHAVIOR OF GROUND WATER IN CLAY GROUND Şaban YURTÇU Department Of Structure Education Afyon Kocatepe University, Instituty of Science and Technology June 2001 Adviser Assistant: Yrd.Doc. Dr. Yılmaz IÇA?A In this study, it was purposed to determine the behavior of ground water using a statistical model including discharge as dependent, and the rainfall, level of ground water and evaporation as independent variables. The skewness of data was corrected by Box-Cox transformation, and lineer outo- rcgressive models (Markov) were implemented. Analysis of periodogram was used to investigate whether the periodical attitude occured in the available data in year. The relationships among the variables were estimated by the correlogram analysis. The dispersion of data was determined throughout the time, and these data were shown in the graphics.
