An Advection Package (MTADVI) dialog box appears. Enter the values shown in Fig. 22 into the dialog box, select Method 0/ Characteristics (MOC) for the solution scheme and First-order Euler for the partiele-tracking algorithm. Click OK to elose the dialog box. 22. The Advection Package (MTADV1) dialog box ~ 1. 2. 3. 4. 5. 6. To assign the dispersion parameters Choose MT3D > Dispersion ... from the Models menu. A Dispersion Package (MT3D) dialog box appears. Enter the ratios of the transverse dispersivity to longitudinal dispersivity as shown in Fig.

2. 1. 2. 3. 4. 5. To assign the parameters for dispersion and chemie al re action Choose MOC3D > Dispersion & Chemical Reaction... from the Models menu. A Dispersion / Chemical Reaction (MOC3D) dialog box appears. Check Simulate Dispersion and enter the values as shown in Fig. 31. Note that the parameters for dispersion and chemical re action are the same for each layer. Click OK to dose the dialog box. To set Strong/Weak Flag Choose MOC3D > Strong/Weak Flag from the Models menu. Move the grid cursor to the cell [25, 15, 1].

13). If Fill Contours is checked, the contours will be filled with the colors given in the Fill column of the table. Use Label Format button to specify an appropriate format. Note. PMWIN will clear the Visible check box when you leave the Data Editor. 8. In the Environment Options dialog box, click OK. PMWIN will redraw the model and display the contours (Fig. 14). 9.
