The method was applied at a project site, yielding hydraulic conductivity values more than an order of magnitude higher than those derived from slug tests, and comparable to values derived from a standard 24-h pumping test. It does this in four main steps : (1) detect screen using. Compared with conventional aquifer testing methods such as short-term pumping and slug tests, the method offers the following advantages: (1) it permits estimation of hydraulic conductivity using fewer data points (2) it is unaffected by the potentially altered, near-well conditions that often affect slug tests and (3) it offers cost and schedule savings by eliminating field work. Figure 1: ColorCrack automatically identifies cracks in arbitrary angled photos of cracked screens. The surrogate pumping test can be analyzed using a simple analytical model to estimate hydraulic conductivity. The data set of a surrogate pumping test contains only a few late-time drawdowns represented by changes in heads at selected monitoring wells in responses to changes in pumping rate at an extraction well. Since 1989 AQTESOLV has been synonymous with excellence in the interpretation of aquifer test data. A hypothesis to estimate hydraulic conductivity from surrogate pumping tests formulated using routinely monitored pumping rates and hydraulic heads is tested. AQTESOLV AQTESOLV (AK-te-solv) is the world's leading software for the design and interpretation of aquifer tests ( pumping tests, slug tests, constant-head tests) in confined, leaky, unconfined and fractured aquifers.
