Hapuku River - measuring sediment transportation

Measuring sediment transport and river changes in the Hapuku River, Kaikoura, post the 2016 earthquake

Te Rūnanga o Kaikōura Research hui

Te Rūnanga o Kaikōura (Ngāti Kurī, Ngai Tahu) hosted a research hui on July 26-27 with participants from NIWA, Cawthron, the Universities of Auckland, Victoria Wellington, and Canterbury, at the Takanga Marae in Kaikoura. The gathering was initiated following Joshu Mountjoy (NIWA) inviting Ngāti Kurī representatives aboard the Tangaroa research vessel to show them the […]

The transformation of a steepland river valley following an earthquake-triggered landslide near Kaikōura, NZ

Tunnicliffe, J., Howarth, J., & Massey, C. 2021, April. The transformation of a steepland river valley following an earthquake-triggered landslide near Kaikōura, NZ. In EGU General Assembly Conference Abstracts (pp. EGU21-10867) In the relatively short and steep catchments of New Zealand’s Alps and Front Range, river systems traverse several process domains, from steep boulder-bed cascades […]

Morphodynamic research challenges for braided river environments: Lessons from the iconic case of New Zealand

Hicks, D. M., Baynes, E., Measures, R., Stecca, G., Tunnicliffe, J., & Friedrich, H. 2021. "Morphodynamic research challenges for braided river environments: Lessons from the iconic case of New Zealand." Earth Surface Processes and Landforms 46.1 (2021): 188-204. Pressures on braided river systems in New Zealand are increasing due to anthropogenic stresses such as demand […]

Sediment Transport Modelling - Hapuku Catchment

This animation shows a model of how the first gravel of a uniform size (16 mm) moves through the Hapuku Catchment. There is still significant amounts of gravel yet to be released and travel through the newtork.

Hapuku landslide dam changes, 2016 to 2019

Surface change models of the Hapuku landslide dam have been generated using Light Detection And Ranging (LiDAR) surveys between 2016-2017, 2017-2018 and 2018-2019. The colours in the two epoch pairs shown below depict areas of erosion (reds to yellows) and deposition (greens to blues). Changes between the surveys can be seen using the slider in […]

Landslide Field Mapping

By Katie Jones, PhD Student in Theme 5: Post-earthquake sediment cascades Together with Chris Massey and Regine Morgenstern, along with fellow PhD students Caleb Gasston and Colin Bloom, we spent 2 weeks in the field during October 2019 and January 2020 visiting a selection of large landslides triggered by the Mw 7.8 Kaikōura earthquake. Unsurprisingly […]
