The Date/Time to Start Sediment Transport allows the user to run the model without erosion and deposition active until the model is stable. After model is stable, the sediment transport is fully activated from the specified time.  The Deposition Limit of water Column Sediments is a value from 0 to 1. This represents the minimum fraction of sediment in the bottom water layer allowed to deposit in a single time step. Setting this to zero would cause 100% of the amount to be deposited in one time step, however, this is also dependent on the settling rate specified.

. The Minimum Water Depth for Shear Stress Updates (m) is the minimum water depth of a grid cell that allows calculating the shear stress.

Erosion Rate Options frame allows user select one of three options with different types of erosion rates matrix data. Details of these options are described in Erosion Rates Option 1Erosion Rates Option 2 and Erosion Rates Option 3 section.

Temporally Varying Erosion Rate Parameters frame is an alternative option that allows user generate a erosion rate matrix from an external file like ASCII or Binary files.
