AbstractIn areas of sub-humid climatic conditions, the moisture received in the form of precipitation is less than the amount that might potentially be used in processes of evaporation and transpiration. Winnipeg's climate is characterized by fairly large and protracted deviations from long-term mean temperature and precipitation conditions. During drought periods, plants draw heavily upon soil moisture in storage in the heavy clay subsoils, and the resulting soil volume change causes serious foundation problems for many engineering structures. The competition of shallow- and deep-rooted vegetation for available soil moisture, the effects of planting or removal of trees on sites, or the covering of large portions of the ground surface with impermeable surfacings on the recharge of subsoil moisture are discussed.
