Additional Physical Format: Online version: Konikow, Leonard F. Three-dimensional method-of-characteristics solute-transport model (MOC3D). Reston, Va.: U.S. A new three-dimensional model of solute transport in ground water that is based on a widely-used two-dimensional method-of-characteristics model, and that is coupled to a . A three-dimensional method-of-characteristics solute- transport model (MOC3D) / By Leonard F. Konikow, G. Z. Hornberger, D. J. Goode and Geological Survey (U.S.) Abstract. A three‐dimensional groundwater flow and multispecies reactive transport model was used to strategically design placement of bioreactors in the subsurface to achieve maximum removal of nitrate along restored stream reaches.

The discrete-fracture, finite-element model HydroGeoSphere (Therrien et al. ) and a discrete-fracture implementation of MT3DMS (Zheng ) were used to model solute transport . A three-dimensional finite-volume ELLAM method has been developed, tested, and successfully implemented as part of the U.S. Geological Survey (USGS) MODFLOW ground water modeling package. A mathematical model consists of differential equations developed from ana-lyzing groundwater flow (or solute transport in groundwater) and are known to govern the physics of flow (and transport). The reliability of model predic-tions depends on how well the model approximates the actual situation in the. William Bleam, in Soil and Environmental Chemistry (Second Edition), 2.F Solute Transport: Plate-Theory Transport Model. Another solute transport model traces its origins to the chromatography field, where it is known as the plate-theory model (Martin and Synge, ).Plate theory represents the movement of a mobile chemical agent through a .

has been derived by first solving the solute-transport equation for an instantaneous point source and then integrating the solution over time. The three- dimensional solute-transport equation for an instan- taneous point source is given by.6(x-X,)6(y-Y,)6(z-Z,)6(t -tr>.

The numerical methods used to solve the governing equations have . A generalized three-dimensional analytical solute transport model with a unidirectional flow field from time- and space-dependent rectangular sources in a bounded homogeneous medium is presented using the first-type (or Dirichlet) source condition at the inlet location of the by: The accuracy of a method‐of‐characteristics model incorporating these changes is evaluated by comparison with analytical solutions for (1) three‐dimensional advection and dispersion in a spherical flow field, and (2) concentration change in a well during an injection/pumping by:
