  • Lapp, Suzan L.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2002Arts and ScienceDepartment of Geography, 2002)
    A wide area assessment of forecast changes in wintertime synoptic conditions over western North America is combined with a meso-scale alpine hydrometeorology model to evaluate the joint impact(s) of forecast climate change ...
  • Pinder, Shawn Douglas; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2000Arts and ScienceDepartment of Geography, 2000)
    Irrigation rates in excess of plant evapotranspiration requirements have been identified as a major contributor to the development of raised water tables in the City of Lethbridge. These high water tables have created ...
  • Booth, Evan L. J (Lethbridge, Alta. : University of Lethbridge, Dept. of Geography, c2011Arts and ScienceDepartment of Geography, 2011)
    This thesis is focused on determining the rate at which the climate of western North America (WNA) has changed in recent history, and looks at the impact that projected future climatic changes will have on a large ...
  • Larson, Robert; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2008Arts and ScienceDepartment of Geography, 2008)
    A modelling approach focused on snow hydrology was developed and applied to project future changes in spring streamflow volumes in the St. Mary River headwaters basin, Montana. A spatially distributed, physically-based, ...
  • MacDonald, Ryan J; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Geography, c2008Arts and ScienceDepartment of Geography, 2008)
    Climate change poses significant threats to mountain ecosystems in North America (Barnett et al., 2005) and will subsequently impact water supply for human and ecosystem use. To assess these threats, we must have an ...
  • Sheppard, Dennis Leslie; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1996Arts and ScienceDepartment of Geography, 1996)
    A characteristic of alpine drainage basins is the very sparse distribution of meteorological recording stations. This study models a contiguous distribution of microclimate and snowpack accumulation in the upper Oldman ...
  • McKechnie, Nicole R.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Geography, 2005)
    Global Circulation Models (GCMs) are used to create projections of possible future climate characteristics under global climate change scenarios. Future local and regional precipitation scenarios can be developed by ...
  • Mori, Julie Y.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2001Arts and ScienceDepartment of Geography, 2001)
    E. coli 0157:H7 were isolated from 0.86% (n=1520) water samples and Salmonella species from 6.04% (n=1456) samples collected within the Oldman River watershed in southern Alberta. Peak prevalence of E. coli0157:H7 in July ...
  • Berg, Aaron Andrew; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1997Arts and ScienceDepartment of Geography, 1997)
    In subhumid to arid climates throughout the world, recharge to groundwater in urban areas is often found to be higher than pre-urbanization rates, despite an increased percentage of impermeable surfaces. Groundwater recharge ...
