• 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 ...

  

• Estimating evaporation for low wind speeds at an eddy correlation site: potential for windbreak evaluation 

  Bardsley, W. Earl; Vetrova, Varvara (New Zealand Hydrological Society, 2019)

  Creating new windbreaks may reduce lee evaporation by reducing surface wind speed (u). However, applying theoretical models to anticipate the extent of evaporation reduction may be liable to error because the physical ...

  

• 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” ...

  

• Evaluating the potential of constructed groundwater systems to improve the water supply operations of Auckland City, New Zealand 

  Brown, Edmund (The University of Waikato, 2002)

  A range of constructed groundwater systems are evaluated for augmenting the potable water supply of Auckland City, New Zealand. The term ‘constructed groundwater systems’ encompasses any constructed means of recharging or ...

  

• Fluxes of carbon dioxide and water vapour at a Waikato peat bog 

  Smith, Jeff (The University of Waikato, 2003)

  New Zealand wetlands are threatened entities and the remaining 15% of pre-European freshwater wetlands are important refuges for plant and animal species, while also providing historical information on past environmental ...

  

• Groundwater flow dynamics beneath a wastewater irrigation site, Hautapu, Cambridge 

  Whatnall, Natasha (The University of Waikato, 1999)

  In this study, a qualitative groundwater hydrological model is developed to assist in evaluating the long-term environmental sustainability of a wastewater irrigation system at Hautapu, Cambridge. The model relies on the ...

  

• Lake level forecasting for hydro power operation in the Clutha catchment 

  Waters, Amy (The University of Waikato, 2019)

  The Clutha River is New Zealand’s largest river, located within New Zealand’s largest catchment. The river runs through two hydro-power stations, the Clyde Dam and downstream the Roxburgh Dam, together providing around 10% ...

  

• 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 ...
