The University of Kentucky Animal Research Center is located in a karst-dominated terrain in Central Kentucky. Continuous monitoring revealed strong diurnal variations in stream water quality constituents at the water shed pour point throughout the year. The time of the day that a stream sample is collected for the determination of stream mass load has been shown to have a significant influence on the estimated stream mass load in a small karst watershed. The mass load estimation bias of the sample time of day is comparable to mass load estimation bias found by other research results using water quality data that is not identified by a sampling time of day.(Download PDF) (Export to EndNotes)
