ESTIMACIÓN DE DATOS FALTANTES DE PRECIPITACIÓN EN LA SUBCUENCA DEL RÍO PATATE

Abstract

Se evaluaron seis métodos de completación de datos faltantes: razón q, razones de distancia, promedios vecinales, regresión lineal, distancia inversa ponderada (IDW) y método del vector regional (MVR); para conocer su aplicabilidad en la Subcuenca del Río Patate (SRP). La escala temporal de análisis fue mensual y comprendió un período entre 1995-2003, en seis estaciones ubicadas dentro del área de estudio. La evaluación de los métodos se realizó mediante diferentes índices que miden el ajuste de los valores observados a los simulados. Los índices utilizados fueron: índice de Nash, coeficiente de correlación de Pearson (R2), coeficiente de determinación (CD) y el error típico. Los resultados demuestran una gran heterogeneidad en los diferentes métodos, siendo el MVR el que mejor resultados presenta para las estaciones: Rumipamba, Querochaca, Cusubamba y Tisaleo. Sin embargo, los resultados para las estaciones Pastocalle y Tisaleo no permitieron seleccionar un método debido al bajo rendimiento de los índices evaluados. Palabras clave: Subcuenca del río Patate, completación de datos, precipitación, vector regional.
