THE QUANTITATIVE EVALUATION OF THE CATCHMENT AVAILABLE GROUNDWATER RESOURCES - THE CASE STUDY

Lech Śmietański

Abstract


Abstract. The paper presents the author's approach to the quantitative assessment of the river catchment available groundwater resources in case of the Łeba River catchment in Poland. A strong emphasis is put on the evaluation of the groundwater flow system renewability which should always precede the resources model simulations. After assessing the catchment recharge using river flow records and a big lysimeter approximation the recharge distribution was calculated using the author's constant volume transformation ((CVT) method. The subsequent construction of the groundwater flow model and application of the CVT method coupled with the virtual wells concept led to the evaluation of the amount and distribution of the available groundwater resources in the catchment.
