Resumen
CONSTAIN, Alfredo y CORREDOR, Jorge. Universality of State Functions that Guide the Dynamics of Solutes in Natural Rivers in "Dynamic Equilibrium": A New Method using Tracers to Calculate Slope. Tecnol. cienc. agua [online]. 2016, vol.7, n.1, pp.89-105. ISSN 2007-2422.
Ever since evidence has existed of a state function φ(t) that guides the evolution of solute plumes in natural flows, the nature of this function has been analyzed from diverse perspectives (Constaín, 2012). This article shows that φ(t) is universal for all flows that meet the "dynamic equilibrium" condition. At the same time, the validity of the Elder in function of φ(t) is demonstrated, which describes the relationship between dispersive transport and the geomorphology, making it possible to calculate the slope of a flaw in a "stable state." This methodology is applied to a medium-sized river in Colombia, verifying that the graph of the peak concentration of the tracer is quite consistent with the expected data when applying the principles described herein.
