Calibration strategies are needed to support the effective use of distributed hydrologic models for operational forecasting. While many distributed models exist (and more are being developed) and new data sources are appearing, comprehensive calibration strategies are proving to be elusive. Most of the current strategies involve the use of scalar factors to uniformly adjust the parameters in all the computational elements. A major limitation of this approach is the emphasis on single basin calibration that does not translate to consistent intra-basin parameter sets. New approaches are needed to perform regional calibration. Potential topics include the use of spatial statistical measures with hard or soft data to infer how to adjust parameters in subsets of computational elements, regularization, effective, and robust search algorithms for automatic calibration and others.
