| 520 | |a"Five locations on the Bow and South Saskatchewan Rivers, varying from a headwater site to a site below urban and agricultural regions, are compared for differences between concentration and flux of sodium and nitrate plus nitrite for the years 1984 to 1986. The hydrological regime displays marked seasonality and differences between upper and lower locations due to differing sources over the year. Two general methods of statistical analysis, both of which account for seasonality, are used to compare locations"--Abstract. |
