1 Programme Room for the River Peter Jesse Rijkswaterstaat, Ministry of Watermanagement, Transport en Public Works, Programmadirectie Ruimte voor de Rivier

2 Content ~ What is the problem? ~ Different measures ~ Implementation ~ Planning ~ Dilemma nature conservation?

3 More than 50% of Dutch people live below sea level or in flood prone areas along the rivers The Netherlands under water

4 Dike breaches in the past

5 Catchment area of the Rhine and the Meuse Netherlands Discharge at Lobith (Rhine) Average: 2,200 m 3 /s Top: 12,000 m 3 /s Peak: 15,000 m 3 /s > m 3 /s (1/1250 per year) Germany France Switzerland

6 In time less space for the river

7 Urbanization has resulted in less and less space for water Arnhem 1830 Arnhem 2000

8 Serious flood risks in 93 and 95 Damage and evacuations

9 Recent European floods ~Floods in Poland en Slovakia: 2010 (highest level of the Tiber for 40 years) (2008) ~Floods in the United Kingdom, Italy, Switzerland and Germany (2007) ~Floods in Bulgaria, Germany, France, Austria and Romania (2005) ~Danube and Elbe floods (2002): 700 dead, 250,000 homeless, 25 billion euros damage

10 ~ Over 10 mln. people are at risk along the Rhine ~ Potential damage: 165 billion ~ Serious environmental consequences, e.g.: Potential flood damage in the Netherlands if water purification plants or factories / toxic chemical storage centres are flooded: ~ destruction of nature ~ decrease in diversity of flora and fauna Historic documentation on floods near Culemborg

11 Things have gone far enough Time for a new approach to flood protection (2000): ~ Continuing to raise dikes is not an option ~ Rivers must get more room for higher discharges Result: prevent higher water levels

12 Concept Room for the River Present situation Old method, raising dikes Not preferable More space for water

13 Double aim Double of Room aim for of Room the River for the River 1. Safety 2. Quality of the environment

14 Room for the River program project area

15 Room for the River characteristics ~ Max. Discharge of 16,000 m 3 /s at Lobith (Rhine) ~ 39 measures ~ Investment of 2.2 billion ~ Work completed in 2015 ~ Design and implementation by local authorities Role of programme management: ~Facilitating and assessing ~Knowledge management and promotion

16 Facts and figures ~Approx. 125 dwellings have to disappear ~Approx. 50 businesses ~1,280 ha decrease in agricultural land ~1,852 ha increase in nature ~20 million m 3 soil transport

17 Different measures flood plain navigation channel dike groyne embankment

18 Room for the River measures 1) Lowering flood plains 5) Lateral flow channel 2) Removing hydraulic obstacles 6) Lowering of groynes 3) Setting back dikes 7) Deepening low flow channel 4) Detention reservoir 8/9) Dike reinforcement

19 Examples of measures: secondary channels

20 Examples of measures: Bypass Veessen (IJsselIJssel

21 Examples of measures: dike relocation near Nijmegen Dike-relocation

22 Examples of measures: Lowering groynes

23 Implementation ~ planning ~ nature ~ housing / buildings

24 Project phases PKB Planning Preparation Realization Land Land acquisition acquisition Permits Permits Transfer Transfer Market analyses

25 Permits: Synergy between flood safety, nature conservation and nature development

26

27 Challenges ~Dilemma nature conservation nature development! ~Role of nature development goals in licensing (?) ~The same maintenance for flood safety as for nature conservation; does it really work? ~With nature as leading principles is there room for other improvements of spatial quality such as recreation and river-front development? ~Can regulation on nitrogen deposit obstruct maintenance options?

28 Thank you for your attention Questions?

29 Land acquisition ~ All the land needed to reach the safety goals ~ Compensation : Generous but not more than legally allowed ~ Generosity applies especially to new floodplains ~ Owners of real property to be expropriated are well in advance given the opportunity to sell at full compensation. ~ Program RfR actively seeks for alternative locations (exchange companies / grounds therefore be purchased)

30 Policy New floodplain areas ~Agreement between state and owners: Full compensation for damages due to flood (inundation damage control) Buyer Guarantee for inland value (only transferable to their own children) Allowing water
