Abstract

The Tagus River Alluvial banks are in the central area of the Tagus Basin in Portugal. Due to its porous hydrological formations and the hydraulic connection to the Tagus River, the alluvial banks show good water productivity at the national scale, but its strategic geographical location is promoting overexploitation of its sources, for the public water supply, agriculture, and industry. This study aims to characterize the geometry of the Tagus River Alluvial banks estimating its depth. The geometry combined with its hydraulic behaviour give ways to predict its capacity to respond under different scenarios of water exploitation. To build the model we follow three main steps, data mining and processing of 60 drilling logs, spatial exploratory data analysis and geostatistical methods. The proposed model is validated with literature review and shows as previous studies do, that the alluvial banks are deeper in the downstream sector.
