title: Isotopic composition of river water across a continent.
abstract: Isotopic composition of water across United States is available and also baseline data prepared for more than 4800 samples (with depth and width-integrated stream samples) from 391 selected sites within USGS National Stream Quality Accounting Network (NASQAN). Data had been analyzed with respect to arrival at National Meteoric Water Line (NMWL). Large number of NMWL water samples has much lower slopes than 8 and intercepts ranging from +10 to -39. These lower slopes and intercepts need a re-look to ascertain coherent δ(2)H and δ(18)O across USA in precipitation. A method is worked out by plotting slopes versus intercepts on δ(2)H axis to arrive at the isotopic composition of water on GMWL and also to look the regional pattern that reflects the origin of vapour mass.
