Operational Water Management at Rijkswaterstaat
• Responsible for operational water management in main waterways
• Operating sluices, pumps and weirs
• 24 h/dag, 365 days/year
• Performed by operators
– sub-task next to shipping management
IWP 2
Rijkswaterstaat
10 watersystems
• Twentekanalen
• IJsselmeergebied
• Amsterdam-Rijnk./
Noordzeekanaal
• Maas/Julianakanaal
• Noord-Brabantse en
Midden-Limburgse
kanalen
• Meppelerdiep
• Kanaal Gent-Terneuzen

Purpose of IWP
To help the operator with
• all the information required
• forecasts
• an operating advice
IWP 5
Rijkswaterstaat
Characteristics IWP
• Focus on real-time water management
• Region tailored system
– Each region is unique
– Workshops with operators
• Suited to the operator’s needs
• Nationwide instrument, nationwide maintenance, regional implementation
• Based on Delft-FEWS
• Realised in 2018

Why Delft-FEWS?
• Easy connection with existing FEWS forecasting models
• Maintenance can be the same as for other FEWS models
• Proven reliability
• But… no dedicated screen displays (they will come!)

Current challenges
• Finding time in the agendas for workshops with end-users
• Data extraction from SCADA systems (closed systems)
• Data exchange with water boards (many systems)
• Simple presentation of scenario calculations
IWP 27

Current challenges
• Finding time in the agendas for workshops with operators
• Data extraction from SCADA systems (closed systems)
• Data exchange with water boards (many systems)
• Simple presentation of scenario calculations
Future challenges
• Realising joint water management among regions of Rijkswaterstaat
• Realising joint water management with water boards
• Realising national infrastructure for data-exchange

Summary
• IWP is an information system for the operators on sluices and weirs
• Is used 24 h/day, year around
• Gives information about
– Present situation
– Forecasts
– Operation advices
• Will be realised for all level regulated watersystems of Rijkswaterstaat
• Benefits:
– improves water level management
– secures the implicit knowledge of the operators
– creates opportunities for joint operational water management
