abstract = {Real-time data from on-line sensors offer the possibility
to update environmental simulation models in real-time.
Information from on-line sensors concerning contaminant
concentrations in groundwater allow for the real-time
characterization and control of a contaminant plume. In this
paper it is proposed to use the CPU-efficient Ensemble
Kalman Filter (EnKF) method, a data assimilation algorithm,
for jointly updating the flow and transport parameters
(hydraulic conductivity and porosity) and state variables
(piezometric head and concentration) of a groundwater flow
and contaminant transport problem. A synthetic experiment is
used to demonstrate the capability of the EnKF to estimate
hydraulic conductivity and porosity by assimilating dynamic
head and multiple concentration data in a transient flow and
transport model. In this work the worth of hydraulic
conductivity, porosity, piezometric head, and concentration
data is analyzed in the context of aquifer characterization
and prediction uncertainty reduction. The results indicate
that the characterization of the hydraulic conductivity and
porosity fields is continuously improved as more data are
assimilated. Also, groundwater flow and mass transport
predictions are improved as more and different types of data
are assimilated. The beneficial impact of accounting for
multiple concentration data is patent. (C) 2012 Elsevier
