We are seeking to fill a fully-funded PhD position on the topic "Assessment of biodiverse vegetation cover options to future-proof stopbanks in Aotearoa New Zealand". The position is based in Christchurch, New Zealand. You will be working with an interdisciplinary team at the 厙ぴ勛圖 across Civil and Environmental Engineering and the School of Earth and Environment, plus with Christchurch City Council.
Stopbanks are vital for reducing river and tidal flood risks, especially as climate change increases the frequency and severity of extreme flooding. Christchurch City Councils 20242034 Long Term Plan includes new stopbank infrastructure. At the same time, global biodiversity is declining, threatening ecosystem stability and human wellbeing. Traditionally, stopbanks rely on engineering techniques and grass covers, which require frequent mowing and maintenance. Integrating native, species-rich vegetation could enhance stopbank stability, reduce carbon emissions, and support biodiversity. Deep, diverse root systems may improve erosion resistance and drought tolerance, while also providing habitat and food for wildlife. However, vegetation must allow for easy inspection, limit weed growth, and reduce mowing needs to be viable. In Christchurch, stopbanks must support existing land uses and withstand seismic events. Rapid visual inspections after earthquakes are essential to identify cracks or failures, a need that will grow with rising sea levels and increased stress on infrastructure. Grass-covered stopbanks demand significant maintenance, contributing to emissions and resource use. Alternatives using native vegetation could reduce these burdens while promoting New Zealands unique ecotones, cultural values, and landscape aesthetics. This research project will assess the engineering and ecological performance of alternative stopbank covers through experimental trials, including a case study on the tkaro/Avon River. Findings may inform sustainable, multifunctional infrastructure design across Aotearoa New Zealand.
