Bonriki 2016

  • The impact of vegetation cover on recharge and the groundwater storage over time to provide technical advice for future planning
  • The impact to the freshwater lens and the salinity at the trunk main under different abstraction rates and climate scenarios to help identify a sustainable yield for an agreed climate condition
  • The identification of galleries which contribute to increased gallery salinity under different abstraction rates
  • Identifying an improved indicie for rainfall to determine impact and recovery on the freshwater lens in Bonriki using the rainfall decile methodology
