Problems encountered when calculating sediment transport with Delft3D 4. https://dlt-acc.firelay.cloud/c/message_boards/find_thread?p_l_id=3231581&threadId=5425589 2026-05-15T21:45:48Z 2026-05-15T21:45:48Z Anonymous Anonymous https://dlt-acc.firelay.cloud/c/message_boards/find_message?p_l_id=3231581&messageId=5425588 2022-11-03T05:50:16Z 2022-11-03T05:50:16Z

I am currently using Delft3D to solve problems in my research project. It is about calculation of river channel erosion and sedimentation. When I mix two sediment fractions on the bed, the diameter of which, for example, are 1.25 mm and 30 mm, and using Van Rijn's formula (1993), sediment transport is wrongly calculated. I think the problem may be related to the implementation of the software, and explain it in detail in the attachment. Could you give me some suggestions to solve this problem?  I would be very grateful indeed for  any help you could give me.
