Aquifer diffusivity (transmissivity divided by storage coefficient) was calculated for three sites near Cortland, New York from water-level fluctuations induced by rises in stream stage. Response data were analyzed through use of a one-dimensional floodwave-response model to calculate the theoretical head response in the aquifer generated by a floodwave in the stream, and then matched to the observed head response. This method of calculating aquifer diffusivity is relatively inexpensive compared to standard aquifer tests and is effective in glacial-valley fill aquifers that are hydraulically connected to a major stream or river.-from Author
