• An association between Waitaki River winter headwater flows and the Interdecadal Pacific Oscillation (IPO) 

  Vetrova, V. V.; Bardsley, W. Earl (New Zealand Hydrological Society, 2015)

  Expressed as 11-year running means (1945- 2008), winter headwater flows in the Waitaki River (New Zealand) and the IPO index show similar patterns in the way they vary over time. However, this effect is not evident in the ...

  

• Cautionary note on multi-component flood distributions for annual maxima 

  Bardsley, W. Earl (Wiley, 2016)

  Multi-component probability distributions such as the two-component Gumbel distribution are sometimes applied to annual flood maxima when individual floods are seen as belonging to different classes, depending on physical ...

  

• Development, testing and application of DrainFlow : A fully distributed integrated surface-subsurface flow model for drainage study 

  Shokri, Ali; Bardsley, W. Earl (Elsevier, 2016)

  Hydrological and hydrogeological investigation of drained land is a complex and integrated procedure. The scale of drainage studies may vary from a high-resolution small scale project through to comprehensive catchment or ...

  

• An expression for land surface water storage monitoring using a two-formation geological weighing lysimeter 

  Bardsley, W. Earl; Campbell, David I. (Elsevier, 2007)

  Field studies have demonstrated that ground surface rainfall accumulation can be detected at depth by synchronous increases in static confined groundwater pore pressures. This opens the way for “geological weighing lysimeters” ...

  

• A general model for temperatures of heterogeneous nucleation of supercooled water droplets 

  Bardsley, W. Earl; Khatep, M.M. (American Meteorological Society, 1984)

  Asymptotic extreme-value theory is used as the basis of a stochastic model which predicts aspects of the freezing behavior of supercooled water droplets. The model gives a general theoretical base to an earlier empirical ...

  

• Evaluating the potential for a multi-use seasonal pumped storage scheme in New Zealand’s South Island 

  Majeed, Mohammed Kadhim (The University of Waikato, 2019)

  A simulation evaluation is presented of the seasonal operation a possible 1,300 MW pumped storage scheme in New Zealand. The simulations are with respect to a site in Central Otago, where the existing Lake Onslow is expanded ...

  

• Selected data exploration methods in hydroclimatology 

  Vetrova, Varvara (University of Waikato, 2016)

  The volumes of climatological data are rapidly growing due to development of new acquisition platforms and advances in data storage technologies. Such advances provide new challenging problems for data analysis methods. ...

  

• Managed aquifer recharge in the Poverty Bay flats? 

  Hampton, George William (University of Waikato, 2015)

  Groundwater use within the Poverty Bay flats has increased over the past 35 years due to land use changes. As a result, groundwater levels within the Makauri and Matokitoki Gravel aquifers are declining at statistically ...

  

• Developing groundwater and surface water interaction methods for complex hydrological systems 

  Shokri, Ali (University of Waikato, 2016)

  Methods and models associated with the interaction of surface-subsurface water flow have been widely employed in many environmental studies over the last decade. However, in spite of considerable effort, understanding the ...

  

• Detecting signals of climatic shifts and land use change from precipitation and river discharge variations: The Whanganui and Waikato catchments 

  Qiao, Ying (University of Waikato, 2012)

  The Whanganui and Waikato river catchments have somewhat different degrees of exposure to the westerly wind systems. It is of interest to determine whether the two regions have similar times of occurrence of any concurrent ...
