Vertical Leakage Occurred after an Earthquake: Suggestions for Utilizing the Mixed Flow Model

Abstract Permeability is an important parameter of shallow crust that affects underground water migration. It to calculate the permeability changes caused by earthquakes for engineering safety and pollutant dispersion. The response analysis groundwater in wells, Earth tides, has been widely used permeability. However, calculation results judgment leakage are controversial. In this study, level both M2 O1 tidal waves Zuojiazhuang well was analyzed. An optimization fitting, using mixed flow model, performed hydraulic parameters aquifers aquitards. After Wenchuan earthquake, horizontal transmissivity increased temporarily then slowly recovered. after Tohoku permanently one order magnitude. vertical conductivity three orders magnitude, meaning occurred. As as constraints with study more precise than those previous ones. This article also gives some suggestions utilizing model.
