Applicability of Literature Values for Green–Ampt Parameters to Account for Infiltration in Hydrodynamic Rainfall–Runoff Simulations in Ungauged Basins

Tügel, Franziska; Hassan, Aziz; Hou, Jingming; … - In: Environmental Modeling & Assessment 27 (2021) 2, pp. 205-231

This study aimed to evaluate the suitability of literature parameter values for the Green–Ampt infiltration model to be used in hydrodynamic rainfall–runoff simulations. The outcome of this study supports to decide which literature values should be taken if observed data for model...

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...

Watershed Modeling to Assessing Impacts of Potential Climate Change on Water Supply Availability

Bekele, Elias; Knapp, H. - In: Water Resources Management 24 (2010) 13, pp. 3299-3320

Climate change could have impacts on hydrologic systems threatening, availability of water supply resources. In Illinois, regional water supply planning efforts are attempting to better understand potential impacts on low flow and surface water availability through analysis of hydrologic...
