Much work has been done by previous workers concerning the estimationof permeability coefficients of aquifer by utilizing electrical sounding results(resistivity of aquifer or factors of strata). In accordance with interpretationof electrical sounding data and results of hydrogeological survey for the wa-ter source north of the Anyang River in Anyang City, the author has putforward a method for calculating hydrogeological parameters by utilizing ma-ximum value of electrical sounding K type curve, and estabished four sortsof regression mode1 for ρ_smax versus k. Studies show that there exists a lo-garithmic correlation between k and ρ_smax. The maps of outcomes compiledthrough calculation(k, T contour maps)prove to be of very important practi-cal value in evaluating hydrogeological conditions of this area, estimating wa-ter-gushing quantity of single well and selecting localities for wells.
