SYSTEM FOR ESTIMATING COEFFICIENTS OF PERMEABILITY IN REGIONAL GROUND WATER SURVEY

Abstract

In a regional ground water analysis by using a quasi three-dimensional finite-element method or the like, it is important to determine the spatial distribution of transmissivity T. Developed in the present study was a system for estimating the coefficient of permeability based on the density measured in situ with a split-spoon sampler with built-in tube. The water levels determined by numerical analysis based on the permeability coefficients estimated by the system were compared with measured water levels to ascertain the validity of the system.
