information (e.g., signatures) from any available data
(even poor-quality, non-concomitant data), which in
combination provide a strong constraint on model
inference; and
(4) an objective framework should be applied, such as
presented in this chapter, to combine the pieces of
information for the purpose of model inference.
The model developed is currently working on-line, forced
by real-time SRE rainfall and Meteosat meteorological
information. It provides the water managers downstream
with real-time information on the expected inflows of the
Cahora Bassa reservoir and can be used to warn the popu-
lation against imminent floods. This PUB study has thus
made a valuable contribution to a societal problem.
