MODELING THE MOVEMENT OF CHEMICALS IN SOILS BY WATER

MODELS DESCRIBING THE MOVEMENT OF CHEMICALS THROUGH SOIL PROVIDE A GOOD EXAMPLE OF APPLYING MODELING TECHNIQUES TO THE SOIL-WATER SYSTEM. SOME OF THE CLASSICAL MACROSCOPIC CONTINUUM THEORIES WHICH HAVE BEEN DEVELOPED ARE PRESENTED HERE IN TABLE FORM. THE EMPHASIS OF MOST STUDIES OF THE MOVEMENT OF CHEMICALS HAS BEEN ON THE INFLUENCE OF STEADY WATER FLOW. RECENTLY APPROXIMATIONS HAVE BEEN MADE TO GIVE BETTER SOLUTIONS FOR NONSTEADY FLOWS. IN PRINCIPLE, FLOW MODELS CAN BE USED TO DESCRIBE THE PROCESSES OF SOIL FORMATION; HOWEVER, THE COMPLEXITY OF SUCH MATHEMATICAL MODELS MAY BE PROHIBITIVE. /AUTHOR/
