b. Correction at a regular cell 



Figure 7. Conceptual diagram showing 

 shoreline and transport corrections 

 at minus and regular cells 



that will place the shoreline at the seawall. In a minus cell, the transport 

 rates at both cell faces are directed outward; therefore, both need to be ad- 

 justed. It does not appear that the adjustments can be specified in a unique 

 way. Hanson and Kraus (1985) calculate corrected transport rates as equal 

 proportions of the original rates, as follows (with corrected quantities de- 

 noted by a superscript asterisk):
