13Direct BoM FTP import of Observed Data
• A great redundancy for observed data.
– Contributes about 10% of the total data count in each 15 minutes time step.
– Great for server maintenance.
Observed Water level Count Observed Rainfall Count
BoM_FTP contributes ~10% data in average BoM_FTP contributes ~12% data in average
14Back up of the back up
• Operational standalone
– Standalone FEWS System
– Including the latest forecast data and observed data in last two weeks.
– Can be used by multiple people at the same time.
– Sharing database over a local network using the Master and Participates
method.
This is a real event
• Working from home.
• Home internet was fine.
• Access to Corporate datacentre was
down.
• Access to Corporate OneDrive was fine.
➢ Download the Operational Standalone
from OneDrive.
➢ Running the system on home network.
➢ Getting the latest observed data from
direct BoM FTP Feed.
15Next Gen Gate Ops
16One step forward • First investigation commenced in 2015. • Adopted in the operational configuration (for testing) in late 2020. • Adopted the Three Nodes approach. – Planning Node: Automatic release plan development (RTC Tools). – Adjusting Node: User to fine tune the gate settings (RTC Tools). – Reviewing Node: Review the potential downstream impacts (URBS).

18Workshops and trainings
• Multiple workshops with the selected engineers
(focus group)
– Useability and underlying assumptions.
– Testing and validation of edge cases.
– Graphical representations.
– Additional scenarios, e.g. gates failure.

20Use of Modifiers
• Save and track engineer’s decisions
through out a flood event.
• Handle the unlikely scenarios. Also
useful for scenario testing.
21Use of plots
• Scatter plot with coloured background
– Visualising historical strategies
– Understand the current strategy
– Tooltip text
22Use of plots
• Customised plot to present additional information
– Customised axis labels 14 timeseries
– Customised plot weights in the plots
– User defined visibilities
4 timeseries

23User of plots
• Customised plot to present additional information
– Consistent colour and line styles.
– Combine different plot types to highlights the information.

26Ongoing projects
27Next Generation Hydraulic Model for Lockyer & Lower Brisbane • Based on the Fast Model from Brisbane River Catchment Flood Study. • Modified input locations to improve run time. • A great collaboration with BMT to develop the post adaptor and additional functions. • Under UAT.
FEWS Calibration dataset
• A Standalone SeqFEWS platform which contains observed data from multiple
sources.
• Observed rainfall data sets are semi-cleaned (up to 90%) using the Spatial
Homogeneity function in Delft-FEWS.
