The proposed methodology represents an approach for estimating hydraulic conductivity and porosity values in presence of spatially distributed heterogeneous materials within the aquifer volume by means of local data such as stratigraphic logs. The idea is to store these information in a hydrogeological database designed for further translating percentages of the different textures in parameters values. Each stratigraphic layer is codified by a 8 digit alphanumeric string, made up of two parts: the first one (digits I- IV) describes the primary texture while the second one (digits V- VIII) the texture presents in lower percentage. Each part is composed by a noun (e.g. gravel), a related adjective (e.g. sandy), a qualitative characteristic of the material (e.g. coarse) and a color. The different percentages of the materials composing every layer are obtained by assigning a specific weight to the first two positions of each part of the code (I, II and V, VI). Literature values for hydraulic conductivity and porosity for the main textures (gravel, sand, clay) are taken into account and weighted according to the same scaling approach. The obtained values are not average values for the whole aquifer thickness but can be calculated for different depth intervals as scaled values.
