• Construct sediment budget for the Waipaoa basin for specific time periods as constrained by dated terraces spanning the last 100ka
• Establish differences in mechanism drivers, scale and timing of periods of slope adjustment due to river incision across subcatchments within Waipaoa basin
Reliant on Good Databases
• Improve knowledge of terrace ages through tephra analyses and GPS especially in tributary catchments
• Intensify work on Holocene terraces
• Establish timing of major periods of sedimentation and storage volumes in tributary valley floors
• Improve knowledge of subsurface geometry of tributary streams and the main stem of the Waipaoa
