Confirmation Of The Water Quality Model Ce Qual R1 Using Data From Eau Galle Reservoir Wisconsin

A one-dimensional model (CE-QUAL-R1) of water quality of reservoirs was evaluated using data collected on the Eau Galle Reservoir, in west-central Wisconsin. Data collected on the Eau Galle Reservoir, in west-central Wisconsin. Data collected in 1982 were used for confirmation. Graphical and statistical comparison were made for over 6.500 samples representing 21 variables. The statistical test used for comparing measured versus predicted values was the Reliability Index (RI). The average RI for each variable indicated that precision was always better than a half-order of magnitude, even for variables that ranged over more than three orders of magnitude. Graphs are presented for all variables, including profiles for the date with the poorest predictions (according to the RI). In addition, comparisons of measured and predicted flux values were satisfactory, helping to ensure that reasonable predictions were made for the correct reasons.
