Aspects of ground effect modeling
The Journal of the Acoustical Society of America, 2011A recently published one-parameter ground model based on Darcy’s law is here generalized into a two-parameter model which depends on an effective flow resistivity and an effective layer depth. Extensive field measurements of the acoustic impedance of various ground types have been carried out for frequencies in the range from 200 Hz to 2.5 kHz.

Ground Effects in STOL Operation
Journal of Aircraft, 1971The effects of operation near the ground are of primary importance in determining the takeoff and landing characteristics of STOL aircraft. A study is presented which compares the results of theoretical analysis with those of wind-tunnel tests using a fixed ground plane with blowing boundary-layer control as well as the moving belt ground plane.
