Аннотация: Watershed research begun in 1960, with initial emphasis placed upon instrumentation of experimental basins. Marmot Creek Basin was selected to study the hydrology of spruce-fir forest. In late 1962, the first streamgauge was constructed, following installation of five meteorological stations earlier in the year. During 1963, meteorological instrumentation was expanded and additional controls installed on the three main tributary streams. Basin inventory, comprising soil and geophysical survey, habitat-type mapping, timber inventory and improved aerial photography was begun. Groundwater measurements is envisaged.Then a second experimental basin has been chosen. The hydrology of montane trembling aspen forests and associated grasslands will be studied there, through instrumentation emplaced in 1964. Other basins with lodgepole pine cover will be selected in 1964. Meteorological and hydrometric networks are simultaneousley being critically examined and improved. Studies to establish the relationships between various environmental and biological factors have commenced. Land classification methods have been explored. Studies to classify surficial deposits on the basis of relative susceptibility to erosion when disturbed by logging have followed.
