The real-time flood monitoring models as a service
Revision january 2012Ps1 Discharge computation
Compute the water discharge (Out1.1) for a given observation station. The computation is based on the current water stage (In1.1) and the stage-discharge relation of the observation station (In1.2).
Ps2 Stage n-days prognosis
This processing service predicts water stage (Out2.1) for a given observation station based on:
- current stage (In2.1)
- upstream stations water stages (In2.2)
- historical stage values for given observation station and a set of upstream observation stations (In2.3)
The output is a time series of water stage for following n days (lead time). For each day within lead time, an uncertainty level is provided.
Ps3 Dam water evacuation
Dam water evacuation service proposes an evacuation plan (Out3.1) depending on following inputs:
- discharge prognosis (In3.2)
- planned energy production (3.1)
- dam constraints (volume, minimum and maximum water levels, gates characteristics : width, opening, etc.) – In3.3
- upstream and downstream water stages (In3.4)
- water discharge (In3.5)
- dam water stage (In3.6)
The evacuation plan will propose:
- the gates that have to be open
- the opening of each gate
- the opening time interval
The water is evacuated through evacuation gates and / or hydro-power units (producing electrical power) and is strictly ruled by a joint (Romanian-Serbian) hydro-power plants regulation.
Ps4 Flood alert
Flood alert service evaluates the current water stage and the prognosis (In4.1, In4.2) and depending on stage thresholds (In4.3) in the observation points outputs a flood grade alert. This could be graphically represented on a map.
