Reply to the Comment on “Wave climate, sediment supply and the depth of the sand–mud transition: A global survey” by D.A. George and P.S. Hill [Marine Geology 254 (2008) 121–128]

An analysis of concepts presented by George and Hill [George, D.A., Hill, P.S., 2008. Wave climate, sediment supply and the depth of the sand–mud transition: A global survey. Marine Geology, 254, 121–128.] regarding the depth of the sand–mud transition (hSMT) was performed by Guillén and Jiménez [Jorge Guillén and José A. Jiménez, Comment on “Wave climate, sediment supply and the depth of the sand–mud transition: A global survey” by D.A. George and P.S. Hill [Marine Geology 254 (2008) 121–128], Marine Geology, in press]. We are pleased that our proposed definition of the hSMT was confirmed to be appropriate. We are encouraged that the authors agree that wave period and wave height should both be used to determine hSMT as we demonstrated in our Eq. (1), which calculates the bed shear stress at hSMT. More in-depth research should focus on characterizing the role of sediment supply in determining hSMT.
