“…Typical time-dependent methods that are frequently used in hydrological DA include the linear KF (Kalman 1960) and its variants, such as the Extended KF (EKF) (Puente and Bras 1987), the Ensemble KF (EnKF) (Evensen 1994b), the Unscented KF (UKF) (Wan and Van Der Merwe 2000), the PF (Pham 2001, Moradkhani et al 2005a, Weerts and El Serafy 2006, and the H-infinity filter (Moradkhani et al 2005a, Wang and Cai 2008, Lü et al 2010), among others. There are also some alternative approaches to solving specific issues in hydrological DA, most notably in the application of a genetic algorithm (GA) in the estimate of pixel-based soil hydraulic parameters for hydroclimatic modelling (Ines and Mohanty 2008) and evolutionary-based assimilation in streamflow simulations in ungauged watersheds (Dumedah and Coulibaly 2012). The spatial variation of the relationship between the background field and observation field of the variable in question is of less concern in time-dependent methods.…”

“…Although it increases the computational cost, the EnKF is one of the most widely used hydrological DA methods. Despite some comparison case studies (Reichle et al 2002b, El Serafy and Mynett 2004, Dumedah and Coulibaly 2012, there is no critical review that specifically focuses on the KF. The objective of this review is to fill this gap by assessing the latest developments and analysing the challenges of Kalman-type hydrological DA, especially the EKF and EnKF.…”

“…The EDA is a fairly new DA methodology that employs an advanced analytical evolutionary strategy to merge and account for uncertainties in model prediction and observation data. Evolutionary algorithms have been applied in several hydrological studies including [Dumedah et al, 2012;Ines and Mohanty, 2009;Chemin and Honda, 2006], and the EDA has been applied in assimilating soil moisture [Dumedah and Coulibaly, 2012a;Dumedah et al, 2011], and streamflow in gauged and ungauged catchments [Dumedah, 2012;Dumedah and Coulibaly, 2012b].…”
