Modelo de distribución espacial continua de d18O en la precipitación en la provincia de Burgos. Desarrollo de la metodología y aplicación en hidrología

Abstract

The main aim of this paper is to develop a methodology to obtain a continuous spatial distribution of isotopic 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 development of this methodology have been made and tested in a limited part of Spain, the province of Burgos, where the resulting map of d18O in precipitation has been compared with isotope data from river water and ground-water
