APPENDIX D: SURVEY DATA FOR DREDGED AREA
AND SAMPLE POINTS
The data in Table D1 were obtained from 30 September to 2 October 1996 as part of the
sampling and evaluation tasks for the dredge project. Water depths are referenced to the
water surface at the time of surveying. Flooding tides (10.1 m max.) occurred from 25 Sep-
tember to 1 October. Surveying was done using a Leitz SET4B electronic total station and a
triple reflective prism mounted on a 1.45-m-tall prism rod.
Table D2 contains survey data for nonperipheral dredged areas. These points were used
to weight the average depth calculations for reporting purposes. They are more representa-
tive of the overall depth of dredging as they are measured away from the edge slumping.
