Project File:Constituent Transport – Optional

3.11.1 Contaminant Transport - Required

Card	Argument	Description
OV_CON_TRANS	none	Specifies overland contaminant transport.

3.11.2 Contaminant Transport Parameters – Required

Contaminant transport parameters must be specified in the Mapping Table. See description of inputs in Mapping Table Section - Chapter 12

3.11.3 Optional Inputs

Card	Argument	Units	Default	Description
SOIL_CONTAM	none		not simulating constituent in soils;	Specifies active soil contaminant tranport. Requires GREEN_AMPT INF_REDIST or INF_LAYERED_SOIL
MIXING_LAYER_DEPTH ##.##	real	m	TOP_LAYER_DEPTH or depth of the top layer in the multi-layer G&A method	Depth of active mixing layer. Requires GREEN_AMPT INF_REDIST or INF_LAYERED_SOIL.
SOIL_STATIC_CONC	none		surface soil concentration not static	Concentration in the surface soil layer will be static for the duration of the simulation. Requires SOIL_CONTAM.
SOIL_NOFLUX	none		fluxes between soil layers computed	No flux of constituents between soil layers due to water fluxes. Uptake from soil surface still occurs. Requires SOIL_CONTAM.
CONTAM_MAP filename	file name	Kg or mg/Kg		File name that contains map of contaminant loadings (Kg), or soil concentration (mg/Kg) if SOIL_CONTAM card is specified, for simple constituent one. Values for all other constituents will be prescribed with the mapping table. All other values in the mapping table will apply for constituent one.
CHAN_CON_TRANS	none			Specifies active channel contaminant transport.
CHAN_DECAY_COEF ##.##	real	d-1	0.0	First order decay coefficient of constituents in channel
CHAN_DISP_COEF ##.##	real	(m2 s-1)	0.0	Channel dispersion coefficient.
OUT_CON_LOCATION "filename.ocl"	file name	ppb		Output file containing columns, first of time then constiuent concentration (ppb) for each constituent. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. Requires IN_HYD_LOCATION. Outputs concentrations for each contaminant at each link/node pair in the IN_HYD_LOCATION file in the order listed in the IN_HYD_LOCATION file and the contaminant mapping table file.
OUT_MASS_LOCATION "filename.oml"	file name	g s-1		Output file containing columns, first of time then constiuent mass flux (g s-1) for each constituent. Valid only with CHAN_EXPLIC or DIFFUSIVE_WAVE. Requires IN_HYD_LOCATION. Outputs dissolved mass (followed by sorbed mass if doing SED_CONTAM) for each contaminant at each link/node pair in the IN_HYD_LOCATION file in the order listed in the IN_HYD_LOCATION file and the contaminant mapping table file.
ALL_CONTAM_OUTPUT	none			Specifies that all contaminant information is output for every overland cell, every channel node, and every soil cell/layer every MAP_FREQ and HYD_FREQ, respectively. Maps of overland concentration and mass are written for every constituent using the constituent name in the mapping table with the extensions "conc" and "mass", respectively. Tables of concentraion and mass for every channel node are written for every constituent using the constituent name in the mapping table with the extensions "chan.conc" and "chan.mass", respectively. Use of this option can result in an enormous amout of data being written.
