MOC: Method Of Characteristics

DESCRIPTION

MOC is a groundwater flow and quality model based on the Method of Characteristics. It allows the simulation of a non conservative pollutant in the satutated zone of a confined aquifer. The aquifer may be non homogeneous and anisoropic and the program can take into account convective transport, hydrodynamic dispersion, diluition due to external recharge and chemical reactions. It is very flexible and can be adapted to a wide variety of situations. tThe model works on a regular grid of 40 x 40 cells for flow computation and 20 x 20 cells for pollution transport (version 3.0).
