Relación entre las propiedades biofísicas con parámetros de modelos hidrológicos conceptuales en la micro-cuenca alto-andina del río Zhurucay

Abstract

In thehigh-Andeanecosystemssuch as thewetmoor, monitoring and lack of education are a problem, whichisaggravatedduetotheincreasingneedfor data flowgeneratedbytheseecosystemstoconductstudiesonmeansproblemsenvironmental. Thusmethodologies for obtainingthis information are sought by estimatesthroughrelationshipsbetweenhydrologicalmodeling and watershedproperties. In thisstudy the benefit of the biophysicalproperties to estimate the parameters of twoconceptualmodels, becauseobtainingtheseis an obstacle to the application of rainfall-runoffmodelswasanalyzed(Xu, 2000). The modelswerecalibrated for River basin Zhurucay, on the moors of Quimsacocha, for a set of parametersdescribing the hydrologicalbehavior, which are used to makecorrelationswith the biophysicalproperties and then the regressionequationsobtainedthatwillbeuseful to estimate the parameters in unmonitored basins. For the evaluation of the performance of variousmodels of efficiencycriteria as the index of Nash and Sutcliffe, BIAS and bands of uncertaintygenerated by GLUE used. The results show that the modelsused are a good representation of the system. While in the correlationanalysis, the mostsignificantparametersconcerningreflectseveralbiophysicalproperties, thus setting equationswereobtained for eachparameter.
