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

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 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
