The paper presents a simple technique which allows prediction of the behavior of the water table in a low pressure water well which doesn't flow to surface. Contrary to the type-curve method used for interpretation of "slug test" data, the permeability and skin are computed using a straight-line approximation. The slope of the straight line and its intersection with the ordinate axis are used to interpret the test data. The presented method is very simple and yields unique results. If the hydrostatic pressures are assumed oposite the water zone, the presented technique is suitable for interpretation of DST flow-period data. The derivation of the presented equations is available from the author.
