dc.description.abstractIn November 2014, Tampa Harbor Entrance Channel was dredged, and material was placed onto Egmont Key. Although the material contained quantities of fine sediment that were greater than the State of Florida “Sand Rule” criteria, an exception was made to allow placement of the sediment directly onto the beach due to the critically eroding west shoreline of the island. Material was placed in a traditional beach nourishment template at the northern portion of the island and in a cross-shore swash zone placement approximately 0.8 kilometer south of that. Beach profile surveys were collected to document morphology change of the two types of nourishments and to illustrate cross-shore location of each sediment sample. Core borings and surface sediment samples were collected and analyzed to quantify fines loss from sediment source to placement site. Although the core borings taken in the dredging area indicated an average of 20.7% fines, the surface sediment samples on the dry beach only yielded 1.9% fines on average, which is within the Florida “Sand Rule” regulation. The post-construction surface sediment samples had a similar color to the pre-construction samples.en_US
