| Abstract | ||
| A general computer program listing is developed that can mathematically simulate one, two, and three dimensional non-steady advection-dispersion contaminant transport in a heterogeneous subsurface media. Programming techniques, involving time varying, point, line and/or area sources of contamination but not a pulsing contamination on the media. The discussion of the modeling digital techniques includes the necessary mathematical background documented program listing, and job setup procedure. A finite difference approach is used to derive and formulate the equations of advection dispersion phenomena. A modified alternating direction digital implicit method is used to solve the set of resulting finite difference equations. The program included is written in FORTRAN IV and operates with any set of units. After the model has been run, it is found that the pollutant of concentration 1000mg/liter at the western polluted boundary reaches the river with concentration of 96mg/liter after a period of 905.6days since the model started | ||
