PROGRAMA CHAC
COMPLETADO DE DATO
PROGRAMA CHAC
CALCULO HIDROLOGICO DE APORTACIONES Y CRECIDAS
La aplicación CHAC a sido desarrollada por el Centro de Estudio Hidrográficos del CEDEX
(ESPAÑA) con metodología propias con el fin de proporcionar una herramienta útil para el
desarrollo de trabajos hidrológicos. Se trata de una aplicación desarrollad en Visual Basic para
MS WINDOWS, con subrutinas de cálculo en Fortran 77, de fácil manejo a través de una interfaz
gráfica.
Completado de Datos:
Para completar las lagunas en las series de datos, se utiliza el menú Completado de Datos. A
partir de un modelo de regresión bivariado con estacionarización previa mensual las series de
datos (CORMUL) se completan, bajo determinadas condiciones impuestas por el usuario, las
lagunas existentes en las series de datos de un fichero LEMA.
La secuencia de cálculos para la realización de la correlación múltiple queda especificada en el
fichero de resultados intermedios. En primer lugar aparecen las matrices correspondientes a los
datos mensuales de las estaciones seleccionadas para el completado en el periodo de estudio
escogido. Son estaciones seleccionadas aquellas que tienen más de cinco datos en cada uno de
los doce meses en ese periodo seleccionado.
La elección de la pareja de estaciones que va ser utilizada para el completado de cada una de las
lagunas de una estación dada se basa en considerar un umbral mínimo del coeficiente de
correlación multiple ponderado según la expresión de la matriz de priorización.
