Desarrollo de la metodología y aplicación en hidrología T1 Continuous spatial distribution model of d18O in recent precipitation in Burgos province (Spain). Methodologydevelopment and application in hydrology A1 Rodríguez Arévalo, Javier A1 Castaño Castaño, Silvino A1 Díaz Teijeiro, M. F. A1 Marcos, L. A. A1 Vázquez Marroquín, M. AB The main aim of this paper is to develop a methodology to obtain a continuous spatial distribution ofisotopic composition in precipitation over Spain. The methodololgy applies Geographic Information Systems(GIS) tools to a polynomial model that relates d18O to latitude and elevation. First steps in the developmentof this methodology have been made and tested in a limited part of Spain, the province of Burgos, wherethe resulting map of d18O in precipitation has been compared with isotope data from river water andground-water YR 2007 FD 2007 LK http://hdl.handle.net/10272/8369 UL http://hdl.handle.net/10272/8369 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
