1. The use of numerical models in hydrology have been an active area of research for at least 60 years. Therefore there is a large number of review articles and technical documents related to this topic such as: Abbott and Refsgaard (2012) Carrera et al. (2005) Doherty and Hunt (2010) Franssen et al. (2009) Linde et al. (2015) McLaughlin and Townley (1996) Pechlivanidis et al. (2011) Poeter and Hill (1999) Vrugt et al. (2005) Zhou et al. (2014) Zimmerman et al. (1998) White et al. (2020)
2. and books for example Anderson et al. (2015) Doherty (2015) and Hill (2006). Saltelli et al. (2008) provides a good general introduction and review of sensitivity analysis methods for mathematical models.
3. A comparison of seven methods for the inverse modelling of groundwater flow. Application to the characterisation of well catchments
4. A Reassessment of the Groundwater Inverse Problem
5. Catchment scale hydrological modelling: A review of model types, calibration approaches and uncertainty analysis methods in the context of recent developments in technology and applications;Pechlivanidis I.;Global NEST Journal,2011
