6 Overview presentation Policy and Program Implementation Issues and Challenges Major floods trigger expertise Delta Commission Water Policy and Program Water Policy and Program and Implementation 1. Risk Assessment and Asset Management 2. Safe Dikes 3. Room for the River 4. European Directives

7 Major floods trigger expertise - Flood events part of our national history - Elizabeth flood (1421) major disaster in southwestern part of the Netherlands dike breaches

8 Major floods trigger expertise Zuiderzeevloed Try out dams/dikes (Amsteldiep, 1920) - First major land reclamations (Andijk, Wieringen, 1927, 1929) - 32 km Closure Dam (Afsluitdijk, 1932) - Three major land reclamation polders ( ) - New science, hydraulic flow, tidal currents, closure methods, pumping stations

9 Major floods trigger expertise Ramp van dike breaches, 1835 people dead - Delta Commission, new approach: shortening coastline risk based approach: frequency analyses, fault trees, economic risks new era of tidal closures: caisson, sand closures, open dams salt and fresh water management growing importance of environmental aspects 1953 Zeeland Flood Delta Projects

10 More recent failures

11 And near misses. Policy adjustment after 1993/ emergency law for speedy dike reinforcement with - adjusted shortened procedures (EIA) - reinforced flood plain management - Room for Rivers philosophy

12 Delta Commission (2nd) 1953 First Delta Commission 2008 Second Delta Commission Veerman Climate change & future challenges Be prepared.pro-active Recommendations on flood management Short term and long term (extreme) scenario's Main focus on water quality and quantity Increased investments Acknowledgement of close interaction with planning, development, environment, social and economic aspects

13 Water Policy & Program National Delta Plan: - Short term measures to meet long term goals - Adaptive Delta Management - By research, monitoring and development of new concepts - National government, Provinces, Local Authorities and Waterboards - Close involvement from private parties, consultants and universities. - Annual update on progress to National Parliament

14 Water Policy & Program National Delta Program - Flood safety (health check, future scenarios and new methodologies) - Fresh water (quantities, preparedness, roles and responsibilities) - Reservoir management (safety and control) - Delta cities (future developments) - Planning and zoning - Policy recommendations in National Water Plan ( )

15 Water Policy & Program Implementation National Water Plan ( ) Roles, responsibilities and future challenges Research program on flood protection and management - Safety standards update - Delta dikes - Floodplain safety - Multi-layer safety approach Working programs on flood protection 1. Risk assessment and Asset Management 2. Safe Dikes (along rivers and coastline) 3. Room for the River 4. European Directives

16 Water Policy & Program Implementation Planning and development, zoning flood risk Understanding probabilities of flooding Quality of flood defence system? Overtopping of defences? Strength? Quality of flood defences? Or probability of flooding, personal flood risk? Ongoing flood protection activities 1.1 Mapping of flood risks 1.2 FLORIS (quantifying risk of flooding) 1.3 Asset management (Operation & Maintenance)

17 1.1 Risk Assessment (Mapping) EU Directive Flood Hazard and Risk maps (

18 1.2 Risk Assessment (to date) Failure modes Afgekeurd Goedgekeurd Geen oordeel 2007 Veiligheid Nederland in Kaart pagina 1

19 1.2 Risk Assessment (Floris) Quantification risks of flooding ( ) Quantifying probabilities and consequences Nationwide FLORIS project Better understanding in actual strength Uncertainties and unknowns Prioritization of means and funding Kans Risico Gevolg Low probability High consequence High probability Small consequence 2007 Veiligheid Nederland in Kaart

20 1.3 Asset Management Six year cycle, check on safety mechanisms Dunes, dikes and flood protection structures Check by waterboards, reporting to Provinces Results of third round ( ) - One third of defences does not meet requirements - 1,200km out of 3,500km not ok - 625km is currently under reconstruction - Remaining part to be done in next 12 years 2001 km % 44% 15% 34% 37% 19% Meets standard Does not meet standard No score 2006

21 1.3 Asset Management

22 Working programs 1 Risk assessments (ongoing) Mapping of (high/low) risk area s Level of protection/acceptable risks Condition assessment of flood defence system 2. Safe Dikes along rivers and coastline (2,3 billion euro's) Upgrading all weak spots by 2017 National program & management organization 3. Room for the River (3 billion euro's) Widening rivers, reducing water levels, be prepared for European Flood Directives Transboundary river management

23 2. Safe Dikes Health checks and condition assessments 2001 and 2006 Major rehabilitation program in place for primary flood defence system Over 100 coastal and river projects identified Coordination by national committee (HWBP) Special project, progress reporting in Dutch Parliament 90% of cost by National funding 2,3 billion euro program Waterboards are leading Strict procedures on methodology Monitoring, program management

24 2. Safe Dikes

25 2. Safe Dikes

26 2. Safe Dikes Landscape, environment, ecology, living, working, recreation, services, infrastructure, future developments

27 2. Safe Dikes

28 3. Room for the River Major goal: Reduction of water levels in te river system 3 billion euro , in 40 projects (out of 200 identified) Providing sustainable short term (50yr) and long term solutions (100yr) SMART targets for delta area - In 2015, capacity of river system 16,000 m3/s - Improvement environmental and ecological footprint floodplains - Flexibility in system to deal with increased discharges due to CC flood level 7 8

30 3. Room for the River (IJsseldelta) IJsseldelta Project: Understand the impacts of climate change upon long term planning scenarios See how major spatial planning conflicts in a complex institutional environment can be handled Provide an insight in the use of process management techniques supported by specific technical expertise

31 3. Room for the River (IJsseldelta)

32 3. Room for the River (IJsseldelta) Short-term solution (2015): creating more room for the river by dredging the river bed

33 3. Room for the River (IJsseldelta) Long-term solution (2050): creating more room for the river by creating a flood bypass Possible Bypass route Reservation for long-term measures

34 3. Room for the River (IJsseldelta) Nature & Recreational + + = Railway Hanzelijn Upgrade to 4 lane highway new houses Spatial conflict Incl bypass Initiative by Regional Partners (Province, water board and municipalities) Ambition of the project(team): Combine future spatial plans plus enhance the environmental quality Integrate plans into one spatial plan, technically and financially feasible Province takes the directors role

35 3. Room for the River (IJsseldelta)

36 4. European Directives - Water Framework Directive - Environmental Directives - Habitats and Birds Directive - Strategic Environmental Directive - Environmental Impact Assessment Directive - Floods Directive

37 4. European Flood Directive Pro-active approach towards flood risk management Catchment based approach, transboundary decisions Nature of flooding varies per country Ambitions, budgets, options and acceptance also vary between countries

38 4. European Flood Directive Predictive flood mapping: Identifying flood hazards and areas at risks Community preparedness and resilience Emergency evacuation planning (e.g. traffic models) Decision support for long-term planning Roadmap Preliminiary Flood Risk Assessment (2011) Flood Hazard and Risk Mapping (2013) Flood Risk Management Plans (2015) Coordination via river basin approach Stakeholder & public involvement and consultation Living documents, review & update
