Secondary Application Category:none 
Watershed Description:81 km^2 Dietzh√∂lze (state of Hessen, Germany) 
Calibration Summary:1991-93: daily r2 & E = .84 & .70 monthly E = .91 
Validation Summary:1994-96: daily r2 & E = .86 & .73 
General Comments:The Shuffled Complex Evolution (SCE) method was used to perform an automatic calibration. A strategy to minimize the number of required calibration parameters is also described. 18 parameters were explicitly optimized while 143 were simultaneously adjusted in fixed ratios. The optimization required nearly 8,000 simulations to satisfy the objective function (mean square error). Graphical and tabular flow results are presented.
