Fluctuating Sediments: The Reshaping Influence on the Coastal Environments of Te Tai Rāwhiti and Te Matau-a-Māui

"We're of the opinion now that actually, if we can drive on the roads, then it's a good day."

Utilising sediment transport modelling proves effective in swiftly identifying areas most vulnerable to sedimentation following severe weather events. The model, crafted for the east coast of the North Island, provides an authentic depiction of sediment movement in the region, although refinement is needed through targeted sampling of sediment and water parameters under various conditions. The Seafloor model holds potential for exploring how adjustments in fishing effort across diverse locations could contribute to recovery after extreme weather events. Improvements can be made by gaining a more thorough understanding of the spatial distribution of seafloor substrates and communities, particularly emphasising the Gisborne region.

The potential for sediment impacts on seafloor ecosystems was evaluated by visually observing the seafloor through towed camera transects. The levels of sediment impact likelihood are indicated by colours RED (High), ORANGE (medium), YELLOW (low) and GREEN (none). The RED RECTANGLES indicate areas which would be expected to have kelp (because they are shallow and therefore should receive sufficient light) but no kelp observed (potentially because of the high sediment concentrations in the water blocking the sunlight) (Source: Report)
