| Abstract |
An analysis of the relationship between air and stream water temperature records for 11 rivers located in the central United States was conducted. The reliability of commonly available water temperature records was shown to be of unequal quality. Simple linear relationships between air (T sub a) and water (T sub w) temperatures were developed for daily and weekly average temperatures and showed some level of accuracy, especially for weekly average temperatures and for small streams. The general equations T sub w = 5.0 + 0.75 (T sub a) and (T sub w) = 2.9 + 0.86 (T sub a) simulated the daily and weekly temperatures of the 11 streams studied with a standard deviation between measurements and prediction of 2.7 C and 2.1 C, respectively. Predictions were better for shallow streams than for deep streams. Periods of ice cover were excluded from the analysis. |
