Bodge, K.R. and Hodgens, E. . 1997. Recovery of a nearshore borrow area for inlet sand bypassing.. FL (USA), FLORIDA SHORE AND BEACH PRESERVATION ASSOCIATION: 215-229.
Beach profiles along a nearshore borrow area, immediately north of Port Canaveral Entrance, were surveyed at 3- to 6-month intervals during an 18-month period subsequent to dredging. The borrow area extends 8000-ft alongshore, between the -4 ft and - 16 ft mlw depth contours. In early 1995, about 1 mcy of sand were transferred from the borrow area to the shoreline immediately south of Port Canaveral Entrance, as part of the inaugural Canaveral Harbor Federal Sand Bypass Project. Thus far, the borrow area's net rate of recovery (200,000 to 250,000 cy/yr) matches the pre-project rate of shoreline accretion. Recovery appears to have occurred progressively from north-to-south, in the direction of the shoreline's almost unidirectional longshore drift. The sand entering the borrow area appears to vertically sort, by grain size, in a manner identical to the pre-project (undisturbed) beach. Pre-project predictions of the beach profiles' equilibration - using both EDUNE and GENESIS methods - match the measured profiles' response exceedingly well. The average, alongshore rates of volumetric accretion within the borrow area and updrift of the borrow area are nearly identical - suggesting that the recovery of the borrow area is not necessarily due to exaggerated transport (diffusion) of sand from the uncut, updrift shoreline. Estimates of the cross-shore distribution of the longshore transport are developed for the first 3 months of the survey data, and correlated with the hindcast distribution of the wave break point and runup limit.
