Site 3: Poverty Bay Coastal Plain3D Model
A LiDAR-derived digital elevation model of the prograding coastal plain of the Waipaoa River, showing a summary of work by Wolinsky et al. (2010; their figs 3 & 4), below.
The elevation colour scale extends from sea level to 10m above. The elevation model is 13.4 km (E-W) by 14.5 km (N-S). Vertical exaggeration is 10x. Key borehole locations show approximate depths. The paleo-shoreline ages (ka = thousands of years before present) are roughly indicative of the progradation timescale - see the paper for more details on their derivation.
