 If DROP is selected, or if a DRY\_TRACKING\_METHOD is unspecified, a particle in a dry position is passed vertically and instantaneously to the water table (if the cell is partially saturated) or to the bottom of the cell (if the cell is dry). This repeats (i.e. the particle may drop through multiple cells) until it reaches the water table. Tracking then proceeds as usual. If the vertical column containing the particle is entirely dry, the particle will terminate upon reaching the bottom of the model grid.
 
-If STOP is selected, particles in dry cells, as well as particles above the water table in partially saturated cells, will be terminated.
+If STOP is selected, dry particles will be terminated.
 
 If STAY is selected, a dry particle will remain stationary until a) the water table rises and tracking can continue or b) the simulation ends.
