Hydromax is a real-time application for riverflow forecasting which is developped by CESAME and is operational at SETHY
(Service d'Ètudes Hydrologiques, Walloon Ministry of Public Works - Belgium) for the management of flood alarms and the
on-line information of the rescue services in the Meuse river basin.

From the telemetering network to
Hydromax
Hydromax is connected with the
telemetering network of SETHY. This
network is essentially made up of water
level chart recorders and rain gauges. All
the remote measurements are stored in a
hydrological data base on the central
computer. The forecasting computer is
connected to it on-line (Fig.1).
The main features of Hydromax
Direct connection with the telemetering data base.
Shor t term r iverf low forecasting only based on hydrological measurements.
Long te r m r i ve r f l ow forecasting based on hydrological measurements and meteorological forecasts.
Data processing and model performance analysis.
The advantages of Hydromax
Data saving : only rainfall and riverflow data are needed. A detailed physical description of the basin is not required.
The identified parameters remain valid from a flood to another : the models are systematically validated on floods which are not used for the model identification.
Friendly user design in order to meet the requirements of an efficient real time forecasting.

Hydromax provides both short term and long term riverflow
forecastings. This is illustreted in Fig.3 where typical windows of
Hydromax are presented.
The short term prediction (blue dot) is computed from on-line field
measurements (rainfall and discharge).
The long term forecasting (red curve) is computed from
meteorological forecasts.
The green curve is the riverflow forecasting without rainfall. It is the
most optimistic hypothesis.
