Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Analysis of drawdown data from pump tests in channel aquifers - as for example, buried bedrock channels - can be cumbersome when leakage effects and boundary effects set in simultaneously. Bukhari et al. (1969) have described a method for determining the leakage factor for cases where transmissivity and storativity can be determined from the early part of the drawdown data. Vandenberg (1976) has shown that if the distance measured along the axis of the channel between the pumped well and the observation well is greater than the width of the channel, the time-drawdown curve at the observation well can be closely approximated by assuming linear flow in the aquifer"--Abstract, p. vii.
