Nonlinear differential equation of drain spacing
Nonlinear partial differential equation governing spacing of horizontal, parallel, subsurface, agricultural drains is solved numerically by finite difference methods; differential equation is based on Dupuit-Forchheimer assumption; solutions are presented in form of dimensionless curve families whose abscissas are time parameter and whose ordinates represent maximum water table height between drains, rate of discharge, and volume of water removed; individual curve parameters establish depth from drains to impermeable barrier which can vary from zero to infinity; example of application is given.
