Abstract

Isotopic Composition of Water in Precipitation Falling at Different Altitudes

An attempt has been made to understand the original isotopic composition of water in precipitation at different altitudes i.e., is it the same ?original isotopic composition? contributing to different altitudes and modified in the transit by local climate and topology? This is popularly known as ?altitude effect? of isotopic composition of water in precipitation. This has been done using available data in the studies in Guadiana Menor Basin, Southeast Spain to get plot δ18O versus δ2H and to get LMWL at different altitudes. Further new method is evolved by the plot of slope versus intercept in LMWL at different altitudes to get the variation of isotope of δ18O and δ2H with altitude and suggested that it is better approach than by in individual observations of δ18O and δ2H with altitude.
