Simulation system for the prediction of water flow and solute transport in partially saturated soils


, : Simulation system for the prediction of water flow and solute transport in partially saturated soils. 7th International Conference on Computers in Agriculture, Orlando, Florida, USA, 26-30 October, 1998: 225-232

A numerical scheme of Richards' equation in its bidimensional form is presented. The finite difference scheme was obtained using the integral interpolation method. Integrals were evaluated considering weight factors in the extremes, so the resulting scheme was a Crank Nicholson type.

Opaque rings on sectioned otoliths from warsaw grouper, Epinephelus nigritus (N = 124), and black grouper, Mycteroperca bonaci (N = 172), were used to estimate age and growth. The aging structures from warsaw grouper were obtained by dockside samp...
