Gravelly Alluvial aquifer of Usora river is developed suitable for water-supply management Of the Usora region. It is a shallow uncon-fined aquifer of high conductivity. Its thickness reaches up to 4.5 meters, unconformably overlying Pliocene clays. The cover above this gravel-dominated layer is thin, partly permeable or completely missing. The aquifer is in fairly good hydraulic continuity with Usora river flow. Capacity of planned wells will lie directly dependent on the well-site positioning to optimal hydrogcoiogical conditions, well-construction modifications to critical flow values for the minimal water level periods, and particularly, on well screen-type selection and construction. Results obtained so far confirm the potential well capacity within range of 5 to 10 l/s (the paper is published in Croatian).
