• 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 ...

  

• The bounded inverse Weibull distribution: An extreme value alternative for application to environmental maxima? 

  Bardsley, W. Earl; Vetrova, Varvara (Elsevier BV, 2021)

  There has long been interest in making inferences about future low-probability natural events that have magnitudes greater than any in the past record. Given a stationary time series, the unbounded Type 1 and Type 2 ...

  

• 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 ...

  

• Enhancement of the Hooghoudt Drain-Spacing Equation 

  Shokri, Ali; Bardsley, W. Earl (ASCE-AMER SOC CIVIL ENGINEERS, 2015-06-01)

  The Hooghoudt equation is widely used as a simple means of specifying drain spacing when designing networks of parallel drains in drainage systems, based on estimating the maximum water table height between two drains. It ...

  

• Studies of source area hydrology under indigenous forest and pastoral agriculture in the Hapuakohe Range, North Island, New Zealand 

  Petch, R.A. (The University of Waikato, 1984)

  This thesis describes a systematic study of hillslope runoff processes and stream flow processes from two forms of land use characteristic of the New Zealand steep land environment: indigenous forest (podocarp-hardwood ...

  

• Surface hydrologic modeling and GIS: a case study of the Kaimai Hydropower project catchment, New Zealand 

  Choudhry, Sohail Afzal (The University of Waikato, 1998)

  The recent trend towards spatial hydrologic modeling is due to advances in the field of geographic information systems (GIS). Spatially distributed models take into account the spatial variability within the catchment and ...

  

• 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 ...
