CS&V colors the area, to indicate it has been included in volume computations. CS&V does not draw a solid line (black in example) across the profile, indicating the gap in the data is larger than the user- defined gap distance. No solid profile line means you have a data gap!ġ4 Testing for Gaps Click ‘Graph Options – Data’.ġ 1 Click ‘Graph Options – Data’. 2 2 4 4ġ5 Differing Coverage Before Dredge versus After Dredge Data Only Where Both Surveys Have Data: Computes areas only where ‘before’ and ‘after’ section overlap. HYPACK BEACH VOLUME CROSS SECTIONS FULLįull Length of Before Survey (not recommended): Computes areas based on limits of before survey. ![]() Differences between the volume results in HYPACK and other packages can result based on how the other package handles the problem of unequal coverage.ĬS&V does not care if your lines intersect. CS&V does not care if there are turns in the channel between lines. HYPACK BEACH VOLUME CROSS SECTIONS FULLĬreating lines perpendicular to the channel centerline can exaggerate these errors.
