Efficient accommodation of local minima in watershed model calibration
Skahill, B. E.; Doherty, J. E. - 2006
The Gauss-Marquardt-Levenberg (GML) method of computer-based parameter estimation, in common with other gradient-based approaches, suffers from the drawback that it may become trapped in local objective function minima, and thus report optimized parameter values that are not, in fact, optimized...

Influence of Scale on SWAT Model Calibration for Streamflow in a River Basin in the Humid Tropics
Thampi, Santosh; Raneesh, Kolladi; Surya, T. - In: Water Resources Management 24 (2010) 15, pp. 4567-4578
The Soil Water Assessment Tool (SWAT) was applied to the 2,530 km<Superscript>2</Superscript> Chaliyar river basin in … the SWAT model could simulate streamflow at both scales reasonably well with very little difference between the observed … and computed values. However, the results also indicate that there may be greater uncertainty in SWAT streamflow estimates …
