Resumen

PIZARRO T, ROBERTO; SOTO B, MANUEL; FARIAS D, CESAR  y  JORDAN D, CRISTIAN. Application of two integral hydrologic simulation models, for the average monthly flow estimation, in two basins of Central Chile. Bosque (Valdivia) [online]. 2005, vol.26, n.2, pp.123-129. ISSN 0717-9200.  http://dx.doi.org/10.4067/S0717-92002005000200015.

Two rainfall-runoff models, Témez Model and T Model, were calibrated for Purapel river basin and Achibueno river basin, at Maule region of Chile. Although T Model uses two parameters and Témez Model uses four parameters, more parameters were used in this research by clustering months from a temporal point of view. On the other hand, 66 % of data were used for calibration and the rest for validation. Results show total data variation is explained in 82 % on Purapel river basin through Témez Model and 61 % is explained for Achibueno river basin through T Model. In addition, U Mann Whitney test is used to fit quality. Both models are considered to be good models. Finally, to use Témez Model for Purapel river basin and T Model for Achibueno river basin is suggested.

Palabras clave : rainfall-runoff Models; simulation Models; Témez Model; T Model.
