Flinders University senior researcher Eddie Banks from the College of Science and Engineering and the National Centre for Groundwater Research and Training is part of a recently announced (17th Sept), Ministry of Business, Innovation and Employment, New Zealand, 2019 Endeavour Fund research project. The research collaboration, is being led by Scott Wilson at Lincoln Agritech Ltd, NZ, together with project partners from NIWA, NZ, Technische Universität Dresden, Germany, Aarhus (Denmark), and Lincoln and Canterbury Universities (Leanne Morgan- ex Flinders University researcher), New Zealand.
The $7.97 million dollar research project over 5 years: “Subsurface processes in braided rivers – hyporheic exchange and leakage to groundwater”, will provide new knowledge to improve the long-term management of braided rivers, which provide the majority of groundwater recharge to NZ’s main groundwater systems. The research will develop an understanding of dynamic subsurface saturation processes from field observations made at different scales, using geophysical surveys, environmental tracers, and novel piezometer investigations.
These data will inform detailed hydrological models of river and subsurface river processes, which will enable the correct implementation of braided rivers within the larger-scale groundwater models used to calculate leakage rates. The insights gained will be used to support the various stakeholders for decision making and management for flood control, natural habitat, agriculture and electricity generation. The length of the project will provide some exciting opportunities to capture the temporal dynamics of these braided river systems and how they behave under different flow events.
