Estimation of some geohydrological properties in a set of monitoring wells in Mexicali Valley, B.C., Mexico

Abstract

With the aim of studying the response of the water level related to variations in barometric pressure and the action of theoretical Earth tide, in a set of monitoring wells in the Mexicali Valley; are propose and implement analysis techniques in the time and frequency domain to obtain as result from the calculation of transfer functions and harmonic analysis, values of barometric efficiency and sensitivity to Earth tide, with which under conditions of theoretical static-confined response, was possible to obtain estimates of some geohydrological and geophysical properties as: porosity, specific storage, and compressibility. In five wells considered in this paper were obtained estimates of the properties of the aquifer in a state before and after an earthquake. This work has enabled a better understanding of the parameters that control the processes that occur in the study area.
