(1) Buckingham, 1907: An Appreciation: Buckingham articulated his findings mostly in written prose, without much reliance on mathematics. His foundational ideas are as valid today as when he proposed them. (2) Simplified Method to Estimate [hydraulic conductivity] ... A simple, innovative method is presented to estimate saturated hydraulic conductivity in soil. The only paired data points necessary for this proposed new method are the times when the permeameter is half full and when it reaches empty.
