Hi Mr. Tom. B., Thank you very much for your quick reply, it helps me a lot. I sincerely thank you for your help, Have a nice day, Sam,

Hi, I’m working on complex stratigraphy model of the Aquifer AB (Fig. 4). I have many layers in many place with a zero thickness. To constrain the Stratigraphy model in areas where a stratigraphy unit is missing, I add the unit with the same top and base depth (zero thickness) to the boreholes (Fig. 1). But I have a problem in Pebbles and gravel unit which is not zero in Aquifer A. (Fig. 3 and 4). - Features of the model: 1. About 132 boreholes 2a. 2 aquifers in Aquifer A (1-Sand, marl and silts aquifer and 2-sandstone aquifer) 2b. 2 aquifers in Aquifer B (
