The following information can be edited on this tab:
Start Time: This is the time for the start of the initial concentration profile, it is usually zero.
Flux into Soil: This is the flux of contaminant into the soil at the top boundary up to the start time (usually zero for a start time of zero).
Flux into Base: This is the flux of contaminant out of the soil into the base up to the start time (usually zero for a start time of zero).
Type of Profile: The initial concentration profile can be specified over depth intervals, or for every sublayer. For example, if there were only two different zones with different initial concentrations, then it would be best to specify the profile over these depth intervals. However, if the deposit had a continuously changing initial concentration profile with depth, then it would be better to specify the concentration for each sublayer (the number of sublayers is specified in the entry of the layer data).
If the profile type is Depth Intervals then the second tab will be for entering the Depth Intervals or if the profile type is Sublayers then the second tab will be for entering the Sublayer values.
In addition if the Print Mass into the base Special Feature is selected, the user will be asked for:
Mass into the Soil: This is the mass of contaminant into the soil at the top boundary up to the start time (usually zero for a start time of zero).
Mass into the Base: This is the mass of contaminant out of the soil into the base up to the start time (usually zero for a start time of zero).
