Interpolación con funciones de base radial y el método del sistema diferencial para identificación de parámetros en acuíferos

Abstract

La caracterización de acuíferos es un problema fundamental en Geohidrologí­a. El problema consiste en estimar los parámetros fenomenológicos a partir de datos de alturas piezométricas. Los datos de campo son obtenidos en pozos de observación los cuales son pocos y dispersos en el acuífero. En este trabajo proponemos una solución al problema de estimación en dos partes. Primero utilizamos un método de interpolación con funciones de base radial para generar datos suficientes de alturas piezométricas, después aplicamos el método del sistema diferencial para la estimación de parámetros. Mostramos la aplicabilidad del método en una caracterización del acuífero Silao-Romita en Guanajuato México

Aquifer characterization is an important problem in Geohidrology. The problem consits in estimating phenomenological parameters given piezometric data. In general field data is obtained in observation wells, which are few and scattered in the aquifer. In this work we propose a solution to the problem of parameter estimation in two parts. First we use an interpolation technique by means of radial basis functions to generate suffcient piezometric data, then we apply the Differential System method for parameter estimation. To illustrate the method, we show a characterization of the Silao-Romita aquifer located in Guanajuato Mexico.
