Soil Water DynamicsOxford University Press, 2003 M02 13 - 416 pages This book presents a rigorous mathematical development of soil water and contaminant flow in variably saturated and saturated soils. Analytical and numerical methods are balanced: computer programs, among them MathCad and Fortran, are presented, and more than 150 practice and discussion questions are included. Students are thus exposed not only to theory but also to an array of solutions techniques. Those using the book as a reference will appreciate the careful development of basic flow equations, the inclusion of solutions and methodology currently available only in journals and proceedings volumes, and the examples and calculations directly applicable to their own work. |

Page 298 - In the every-day affairs of life it is more useful to reason forward, and so the other comes to be neglected. There are fifty who can reason synthetically for one who can reason analytically.
Page 135 - When you follow two separate chains of thought, Watson, you will find some point of intersection which should approximate to the truth.
Page 230 - You have formed a theory, then?" "At least I have got a grip of the essential facts of the case. I shall enumerate them to you, for nothing clears up a case so much as stating it to another person, and I can hardly expect your cooperation if I do not show you the position from which we start.

Page 7 - Or is the residual water content. The residual water content is somewhat arbitrarily defined as the water content at which the corresponding hydraulic conductivity is appreciably zero, but very often it is used as an empirical constant when fitting hydraulic functions. Equation (1-8) is often used with 9r = 0.
Page 56 - ReJ^^- (2-1.) where d is an effective pore diameter. The critical Reynolds number is much lower for porous media than for straight tubes, such as those assumed for flow in pipes. Wide ranges have been observed, but generally, for Re < 1, laminar conditions are expected (Scheidegger, 1957; Hillel, 1980).
