| Abstract |
The purpose of the study was to evaluate factors that influence hydraulic conductivity values determined by slug tests in typical monitoring wells. Procedures for conducting tests and methods for analyzing test results are summarized and compared. Sensitivity analyses were conducted to identify and evaluate the factors influencing the calculated hydraulic conductivity values for available slug test solutions. These factors include mathematical approximation of the shape of the screen intake, the presence of a less or more permeable well skin, determination of the radius of influence, formation anisotropies and heterogeneities, partial penetration and boundary conditions, and filter sand pack drainage from wells with screens that span the water table (partially submerged well screens). A method is presented to calculate the filter sand's specific yield from hydraulic head versus time curves for incorporation into existing slug test solutions. |
