Closure to 'Classroom Activities to Illustrate Concepts of Darcy's Law and Hydraulic Conductivity' by Roseanna M. Neupauer and Norman D. Dennis

摘要

The discussers would like to express their appreciation to the authors Neupauer and Dennis for writing about classroom activities to illustrate basic concepts of groundwater flow using a simple apparatus called a Darcy bottle. Although the apparatus the authors used is simple and the tests are largely understandable, some points in their technical paper need to be clarified. In the paper, Darcy's law is introduced to students as a way to calculate the rate of change of one variable in relation to another (Carlton and Nicholls 2001).
