Dinámica fluviométrica y limnológica de un cuerpo superficial de agua asociado a un prado húmedo de los Andes del norte-centro de Chile

Abstract

By using an 18-years database, it was analyzed the behavior of a series of limnological parameters of a surface water body found in a wet-pasture located in the high mountain area of a river basin of north-central Chile. It is documented its stream-flow dynamics and the temporal variation of diverse physical and hydrochemical parameters. The system is characterized by a high temporal variability (both annually and monthly) of the parameters studied. This variability prevented to observe temporal patterns. Unlike the highest stream flow, the lowest flow showed a clear correspondence with the observed precipitation. The hydrochemical characteristics of the water body are consistent with the geological substrate of the study area.
