Project results of Meuse working group
FLOOD-WISE Sustainable flood management strategies for cross border river basins
Fred van den Brink, River Basin Coordinator Meuse
FLOOD-WISE Final Conference 23-10-2012
Contents
• Meuse River Basin • Partners• Actions• Results and lessons learnt• Future cooperation
Meuse River Basin: focus and flood generation
• Province of Limburg (NL)• Directorate General of Region Walloon (W)• Rijkswaterstaat (NL)• Groupe Transversale Inondations (W)• Waterdienst (NL)• Waterboard Roer en Overmaas (NL)• IMC as stakeholder / sound board (NL, Fl, W, F, D, L)
Partners in Meuse wg
Actions• Comparison of methods: flood risk assessment, mapping, management
plans (pilot Gueule)• Confrontation with demands Flood Directive• Identification and exchange of good practices• Recommendations (practical, technical, policy)
• Regional partner meetings: exchange of ideas, inventory reports • Yearly conferences: workshops, political forum
Results: Inventory Reports
1. PFRA-phase: Inventory of water bodies which are at risk
2. FRM-phase: Cross-border flood hazard/risk maps
3. FRMP-phase: Inventory of goals and measures for management plan
1. Assessment: RIVERS WITH SIGNIFICANT FLOOD RISKS
1. Meuse river
2. Inventory of additional tributaries at risk: for cross-border streams applying upstream-downstream rule in province of Limburg. In Wallonia all non-navigational water bodies.

2. Mapping: CROSS BORDER FLOOD HAZARD MAPS
Cross-border mapping involves adjustment of coordinates, and agreement on risk-levels, water depths, models, etc.
Methods:
Hydrological modeling and soil maps
AMICE
3. Planning: building blocks for FRMP

Existing flood management plans are used as a starting point:
• International Flood Action Plan Meuse
• National and regional water policy and water management plans
• Calamity plans
• Plan PLUIES
• Limburg Module for national FRMP
Goals• 1:250 safety level behind primary dikes along river Meuse• Different safety levels along tributaries
Measures:• River widening via the project “Meuse works”: Common Meuse and
Sand Meuse • Dike improvement within Meuse works and further on• Further river widening for
• reducing dike improvement• compensation for the effects of climate change• regional development
• Water storage and river widening along tributaries
FRMP-Protection: examples Limburg
Within FLOOD-WISE, a cross-border Flood Risk Management Plan (FRMP) pilot project on the Gueule sub-basin was carried out.
Main results:• generating a catalogue of measure for implementatiion of
FRMP in Wallonia• establishing of a score system to classify the priority of actions
per river• creating a model for automation of a score system• improvement of data and knowledge exchange with (cross-
border) partners
FRMP “Gueule sub-basin”: pilot implementation of EU Flood Directive in Wallonia
Comparison across the border
Walloon region• Top-down process and
control• Plan Pluies• Many tributaries, high detail
level• Safety standards Meuse,
but no regional safety standards
Province of Limburg• Bottom-up process with
top-down control• Limburg module 2012• Few tributaries, low detail
level• Safety standards Meuse and
regional safety standards
• German (LAWA) upstream-downstream rule • Level of detail: which water bodies, which floods
(causes, return periods)?• Use same definitions: what do we mean with
prevention, protection, calamity management?• Cross-border harmonization of plans: solidarity
principle, better crisis management, better communication: flexibility needed
Lessons learnt
Future cross-border cooperation
• Improvement of online sharing of discharge and water level data
• Examination of cross-border effects of measures• Further harmonization of flood hazard and flood risk maps
and management plans• Dissemination of results in IMC wg hydrology• Interreg: AQUADRA, AMICE, FLOODWISE, …
