Numeryczny model filtracji i transportu masy w wodach podziemnych rejonu składowiska odpadów w Jelczu-Laskowicach

The investigations were conducted to establish an influence of the waste disposal in Jelcz-Laskowice on groundwater. The measurements in the local monitoring network coinciding with other field work let to develop a conceptual model of local groundwater flow system. The next crucial step was to create a numerical model using finite difference MODFLOW solution basing on conceptual model setup in a GMS modelling environment. As a major result after calibration a proper hydrodynamic field in a three-dimensional space was calculated. Afterwards using MODPATH code the pathlines were obtained and the time of advective transport of particles from a waste disposal area to the river was estimated as 90-130 years with average velocity equalling 6,6-8,6 m/a. The final task was creating a transport model in MT3D environment to simulate chlorides plume migration, achieving in the period of 30 years a good fit between observed and calculated concentrations.
