ABSTRACT: Groundwater resources for drinking water supply in mountainous areas are mostly represented by springs, bound to hydrogeological structures with the free water table. Yields represent natural resources which can be estimated using the hydrological balance and base flow separation methods. Proposed groundwater amounts estimation method is based on hydrological balance using long-term precipitation and river discharge data. The inter-relation between the short-term and long-term observation data is based on analogy and mathematical statistic methods. The year wetness evaluation goes out of the ratio between the annual precipitation amount and the long-term precipitation annual average; the standardized precipitation index (SPI) was also used. The base flow value was estimated using the local minimum method, belonging to computerised separation methods in a daily step. The presented way of groundwater natural amounts QPRIR calculation satisfies the requirements of the Annex 3 of the Resolution no. 51/2008 Coll. The value QPRIR is used for calculation of the maximum (natural) usable amount QP, which also considers the global ecological limit value MQEKO. After that sufficiently documented and proved usable groundwater amounts QDOK are calculated. The proposed methods are demonstrated on the case study of usable groundwater amounts estimation in the Trnovec brook catchment.
