    A computer simulation model, LINKFLOW, was developed to calculate the movement of water during various water table management practices, namely subsurface drainage, controlled drainage, and subirrigation. The model can ...
  • Regenerative Trait and Cold Hardiness in Highly Productive Cultivars of Alfalfa and Red-Clover 

    Nowak, J., S. L. Matheson, N. L. Mclean, and P. Havard. 1992. "Regenerative Trait and Cold Hardiness in Highly Productive Cultivars of Alfalfa and Red-Clover." Euphytica 59(2-3): 189-196.
    In earlier work on improvement of persistance in forage legumes, we selected genotypes from highly productive cultivars of alfalfa, Algonquin and Apica (Euphytica 45: 105-112, 1990) and cv. Florex red clover (Plant Cell ...
  • Review of biosolids management options and co-incineration of a biosolid-derived fuel 

    Roy, Murari Mohon, Animesh Dutta, Kenny Corscadden, Peter Havard, et al. 2011. "Review of biosolids management options and co-incineration of a biosolid-derived fuel." Waste Management 31(11): 2228-2235.
    This paper reviews current biosolids management options, and identifies incineration as a promising technology. Incineration is attractive both for volume reduction and energy recovery. Reported emissions from the incineration ...
  • LINKFLOW, a water flow computer model for water table management: Part 2. Model verification 

    Havard, P. L., S. O. Prasher, R. B. Bonnell, and A. Madani. 1997. "LINKFLOW, a water flow computer model for water table management: Part 2. Model verification." Transactions of the ASAE 40(6): 1539-1542. Copyright © 1997 American Society of Agricultural and Biological Engineers.
    A computer simulation model, LINKFLOW, was developed (Havard et al., 1995) to simulate the movement of water during various water table management practices. This article described the validation of the linked saturated- ...
  • Effects of Hydraulic Loading Rate and Filter Length on the Performance of Lateral Flow Sand Filters for On-Site Wastewater Treatment 

    Wilson, Janice, Leah Boutilier, Rob Jamieson, Peter Havard, et al. 2011. "Effects of Hydraulic Loading Rate and Filter Length on the Performance of Lateral Flow Sand Filters for On-Site Wastewater Treatment." Journal of Hydrologic Engineering 16(8): 639-649.
    On-site treatment of residential wastewater is important for rural and remote regions where centralized wastewater treatment may not be feasible. Sand filtration is a proven method for secondary treatment of septic tank ...
  • Performance and hydraulics of lateral flow sand filters for on-site wastewater treatment 

    Havard, Peter, Rob Jamieson, Daniel Cudmore, Leah Boutilier, et al. 2008. "Performance and hydraulics of lateral flow sand filters for on-site wastewater treatment." Journal of Hydrologic Engineering 13(8): 720-728.
    This paper describes the performance of six lateral flow sand filters (LFSFs) for their treatment of septic tank effluent in Truro, Nova Scotia, Canada. This report presents LFSF performance data collected during the first ...
  • Effectiveness of hot water, infrared and open flame thermal units for controlling weeds 

    Astatkie, T., M. N. Rifai, P. Havard, J. Adsett, et al. 2007. "Effectiveness of hot water, infrared and open flame thermal units for controlling weeds." Biological Agriculture & Horticulture 25(1): 1-12.
    Thermal weeding in Eastern Canadian agriculture is relatively new and being considered as a viable tool in organic food production. Hot water (HW), infrared (IR) and open flarne (OF) thermal units were compared in terms ...
  • Computer controlled portable frost simulator for field studies of frost effects on wild blueberries
