    The hydrologic cycle

    Hydrology is the science concerned with the occurrence and distribution of water on and under the earth. Meteorology is the science dealing with the atmosphere and the movement of water, both as vapour and as liquid, in the air. Both sciences are concerned with the hydrologic cycle - the...

    Mean annual lake evaporation

    The map represents the mean value (in millimetres) of the annual loss of water through the evaporation process from the surfaces of open water bodies, such as ponds and shallow lakes and reservoirs based on the 10-year period 1957 to 1966. The greatest mean annual lake evaporation (more than 900...

    Moisture Regions

    Moisture regions illustrate moist (water surplus) and dry (water deficient) climate areas. The regions are a general guide to moisture surplus or deficit to be factored with seasonal timing of moisture availability for the hydrological system, including fluxes to runoff and groundwater infiltration.

    1Freeze-up and break-up of rivers and lakes

    The plate contains four maps showing the mean river freeze-over date, the mean lake freeze-over date, the mean river ice-free date and the mean lake ice free date. The four maps depict, in a general way, the average dates on which freshwater bodies in Canada become completely ice-covered in the...

    Annual snowfall

    The map shows the annual snowfall (in centimetres) based on the 30-year period 1941-1970. Snowfall is measured by inserting a ruler into the new snow at several points to obtain its depth and to estimate the degree of drifting or scouring that has occurred. The water equivalent of snowfall for...

    Annual precipitation

    Precipitation is derived from water vapour in the air, and it includes all forms of moisture falling on the earth's surface. Condensed water vapour accumulates in clouds, and precipitation occurs when the constituent ice crystals or water droplets grow too large to resist gravitational attraction...

    Snow cover measurement networks

    The map shows the location of the snow course stations and the agencies that operate them. Most Canadian snow courses are operated by the federal Department of Fisheries and the Environment and the provincial government departments concerned with water resources. Though the principles of snow...
