About Earl

Journal publications are listed in the orcid link above. I work in a range of fields in theoretical and applied hydrology, including stochastic hydrology and investigating pumped storage possibilities at Onslow (South Island) and Ngaruroro (North Island).

Research Interests

  • Developing hydrological models with optimal simplicity
  • Agent-based groundwater models
  • Pumped storage, hydro power hydrology, and data-based hydroclimatic forecasting
  • Finite mixture models of solute transport in the environment


  • Meridian Energy Senior Research Fellow, 2000-2005
  • Distinguished Visiting Professor, Chinese Academy of Sciences, Beijing, 2011
  • New Zealand Hydrological Society Award For Outstanding Achievement, 2011
