RT Journal Article T1 Aplicación del modelo paramétrico de vulnerabilidad Drastic en el tramo terminal del río Torderá T1 Application of the vulnerability Drastic parametric model to the terminal stretch of Torderá river A1 Spandre, R. A1 Gemignani, N. A1 Giacobbe, G. A1 Nicoletti, F. P. A1 Pardini, P. AB The parametric model Drastic (acronym of Deep water; Recharge, net; Aquifer media; Soil media; Topography; Impact of vadose zone; Conductivity, hydraulic) is applied to the terminal stretch of Tordera River (in the Catalan Region, next to Blanes and Malgrat de Mar) to evaluate the risk of pollution of the underground water. The total area examined, which is covered by a principal aquifer composed of gravel and sands, is divided into more than 700 square cells with a side of 125 m long. It is calculated the vulnerability index PP for each cell, and the whole studied area, on the base of the PP value, is subdivided into 2 classes of risk: a big sector of moderate risk and a small sector of elevated risk PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12936 UL http://hdl.handle.net/10272/12936 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
