EVALUATION OF FLOW RATE IN UNSATURATED ROCK: FIELD TEST WITH INTEGRATED APPROACH

Abstract

The knowledge of the unsaturated flow rate is essentialfor both groundwater protection and management, howeverit is not easy to determine experimentally, especiallyon the rocks and in the field.This study aims to evaluate the flow rate of potentialcontaminants in a porous aquifer using an integrated approachthat combines electrical resistivity measurementswith a large ring infiltrometer test.Specifically, the field tests were carried out on the outcropof sandstone in a quarry, located in Southern Italy,which has recently been affected by mycelium sludge derivedfrom pharmaceutical industry waste. The electricalresistivity tomography was carried out to visualise the infiltrationof water in the subsoil in order to evaluate the unsaturatedwater flow in the sandstone. Simultaneously, thevertical flow into the unsaturated subsoil was investigatedby measuring water levels in a large adjustable ring infiltrometer,sealed directly on the rock. The results of thisstudy confirm the efficacy of the combined methodologiesto monitor the vertical flow through unsaturated porous rock.
