Cardenas and V.A. Zlotnik (2003) presented a constant-head injection test (CHIT) method for mapping hydraulic conductivity of unconsolidated streambed sediments. There is a typographical error (namely, a misplaced parenthesis) in their equation (11) that could lead to erroneous values for the shape factor P . Equation (11) should read: (11) where A and B are coefficients originally defined by Bouwer and Rice (1976), b is the aquifer saturated thickness below the stream, l is the depth to the top of the screen from the stream-aquifer interface, L is the screen length and rw is the piezometer radius. Note that b in the natural logarithm of the second term in the right-hand side of the equation is also divided by rw. Not doing so not only results in incorrect values for P but may also result in negative arguments for the terms in the brackets leading to complex values after taking the natural logarithm. In general, this error does not change conclusions in the original note or the applicability of the CHIT method. We thank Charles F. Pitz of the Washington State Department of Ecology for bringing this error to our attention. References Bouwer, H., and R.C. Rice. 1976.
