where K, φ, Vd, and
D were defined previously (Equations (1-1), (1-54), and (1-63)). The parameter Qτ is the total
amount of material emitted during the time period τ for which the
deposition calculation is made. For
example, Qτ is the total amount of material emitted during a 1‑hour
period if an hourly deposition is calculated.
To simplify the user input, and to keep the maximum compatibility
between input files for concentration and deposition runs, the model takes
emission inputs in grams per second (g/s), and converts to grams per hour for deposition
calculations. For time periods longer
than an hour, the program sums the deposition calculated for each hour to
obtain the total deposition flux for the period. In the case of a volume source, the user must
specify the effective emission height he and the initial source
dimensions σyo and σzo. It should be noted that for computational
purposes, the model calculates the quantity, 
1.3.4 Area and Open Pit Source Emissions
For
area and open pit source emissions, Equation (1‑65) is changed to the
form:

where K, D, Vd, and vd
are defined in Equations (1‑1), (1‑54), (1‑65), and
(1-80). The parameter QAτ
is the total mass per unit area emitted over the time period τ for
which deposition is calculated. The area
source integral is estimated as described in Section 1.2.3.
