Hi All,
I have created a few drain coverages, when I map these coverages to MODFLOW, one stress period before that defined in the original coverage becomes active as a drain.
For example, in the screenshot below in the coverage I define the beginning of drainage at timestep 61 (as indicated by a conductance value of 1).
However, when examining sink/sources for cells defined as a drain using that coverage, the timestep prior to the one defined in the coverage becomes active and is given a conductance value ~ half of that given to other stress periods as shown in figure bel
