Abstract
In this work a method is presented to obtain R-Zε relationships through comparison, in probability, of nonsimultaneous measurements of Zε and R. Range dependent relationships obtained in this way are given for a radar situated at 20°21′30″S, 49°01′38″W. The method is tested by comparing actual river hydrographs from a number of basins with those simulated using data as input to a hydrological model.
