Abstract


IDENTIFICATION OF HYDROGEOLOGICAL PARAMETERS BASED ON MODELLING BREAKTHROUGH CURVE IN MATLAB ENVIRONMENT

Abstract. Series of laboratory column tests with three sizes of columns and two kinds of tracers were performed. As the result the breakthrough curves which showed the dependence of tracers’ concentration on time were obtained. The proceses of water filtration and transport of pollutants in columns were described by appropriate mathematical equations. For the given model the parametric studies were done using numerical solutions obtained by finite element method. The identification of hydrogeological parameters was carried out by the proposed new method using build in function of numerical optimization within MATLAB environment. The results of identification of hydrogeological parameters were discussed.
