Dutch Expertise

Water Management & Flood Control

Delft, The Netherlands, January 2006

1 Introduction

2 Aim of this document

To provide information on the Dutch flood management system and other related systems. We would like to share our lessons learned and provide an overview of Dutch expertise and policies. We invite you to contact The Netherlands Water Partnership (NWP, www.nwp.nl). The NWP is an independent body set up jointly by the Dutch private and public sector to act as a national coordination and information point in relation to water activities overseas.

3 Dutch History in Water Management and Flood Control

The Netherlands has centuries of experience in water management and flood control.Situated in the largest delta of Europe, one third (1/3) of the country is below sea level. Since 8 million people live below sea level, the Dutch have had to learn to live with the water. Without the protection of our levees and dunes, more than half of the country would be flooded. The first levees were built 1,000 years ago, lakes were drained, polders (tracks of land reclaimed from the sea or lakes) were created, and water levels were placed under control. Water management needed to be organized, thus our first democratic institutes, the public water boards, were founded in 1200 AD.

Water boards are decentralized public authorities with legal tasks and a self-supporting financial system. Water boards are responsible for local and regional flood control and water management. The amount received by each water board depends on the level of taxpayer interest within each water board's jurisdiction. As of 1 January 2005 there were 27 water boards with approximately 10,000 employees.

 To protect The Netherlands from flooding, the best expertise available on innovative flood control and water management was and is still needed today. This was brought to light by the floods of 1953 and in the 1990s. During that period, the worlds largest flood protection works were built: the Deltaworks. Not only has hydraulic engineering expertise been developed by both public and private organizations in the Netherlands, but also expertise on flood control, flood planning, risk-based flood protection standards, institutional and legal embedding of policies, crisis management, integration of urban issues with environmental protection, reconstruction activities and dredging technologies

4 Floods
In recent history, three major floods had a deep impact on how the Dutch manage flood and water issues. These disasters made it clear that we needed to improve our flood control techniques and water management policies and standards.

1953 Zeeland sea flood

67 embankment breaches Approximately 500,000 acres of land flooded 1836 people died Approximately 200,000 livestock drowned 3,000 houses and 300 farmhouses completely destroyed Over 40,000 houses and 3,000 farmhouses damaged After 3 months still 24,000 could not return home

1993 & 1995 Rhine and Meuse river floods

Approximately 100,000 acres of land flooded 240,000 people evacuated A major highway was blocked for several weeks Casualties were limited

Improvement of our water management and flood control after the floods
Deltaworks: closes and controls the Delta of Zeeland in case of a storm: Dams Provides storm surge barriers

Legislation: Law on Flood Defense was introduced: Enacted a powerful tool to safeguard the quality of our flood protection Established clear design standards for a safe level of protection against flooding

6 Lessons Learned: Water requires Space

For centuries, spatial planning in the low-lying Netherlands has been a matter of maintaining the separation between land and water. The Dutch have benefited from this separation, considering that two-thirds of the gross national product is generated domestically. However, changes are brewing. Climate changes are increasing the likelihood of flooding and water-related problems. In addition, population density continues to increase, as does the potential for economic growth, and consequently, the vulnerability to economic and social disaster. Two undesirable developments that, in terms of safety, exacerbate one another a growing risk with even larger consequences. As such, the safety risk is growing at an accelerated pace (safety risk = chance multiplied by consequence).

How do we deal with this ever increasing risk?

The Netherlands is changing its approach to water. This change involves the idea that the Netherlands will have to make more frequent concessions. We will have to relinquish open space to water, and not take back existing open spaces, in order to curb the growing risk of disaster due to flooding, We will also need to limit water-related problems and be able to store water for expected periods of drought. By this, we do not mean space in terms of the height of ever taller levees or depth through continued channel dredging, but space in the sense of flood plains. This approach will require more area, but in return we will increase our safety and limit water related problems. Safety is an aspect that must play a different role in spatial planning. Only by relinquishing our space can we set things right; if this is not done in a timely manner, water will sooner or later reclaim the space on its own, perhaps dramatic manner.

More space in relation to technological measures

Technical expertise and capability, in addition to continuing innovation, are essential to our success. However, we have learned that hard technical measures are not sustainable and are not flexible. Technical measures need to be combined with other strategies to be truly successful. The Dutch have developed several strategies or building blocks with proven reliability to provide flexible long term solutions that fit local circumstances. We would like to introduce these strategies in the following pages.

7 Water Management
Climate change and increased urbanization demand changes in our approach to water management. The starting point for flood protection is sustainable water management. It is essential to understand a water system in order to decide on the most appropriate measures for flood protection. In this context, we describe the range of river and coastal management sciences and expertise The Netherlands has to offer.

Current issues

Due to our constant battle with the sea and rivers, the Dutch have had to study and intensively manage our rivers and coast. Our river management expertise includes: Policy development from a national to a local level; the complete range of river engineering and river maintenance works; river hydraulics and sediment transport modeling. Large scale flood event modeling in 3D GIS environment. Our coastal management expertise includes: A high level of expertise in the area of waves, currents, sediment transport, coastal morphology, seabed - structure interaction, ship dynamics, navigation and statistics. We apply state of the art and proven numerical models and have access to a wide range of physical model facilities. We have specialized expertise in coastal protection, coastal development and coastal management, which are related to gravel, sand and mud coasts. We offer expertise in the field of: coastal morphodynamics and design conditions for coastal areas; shoreline management, including analysis of coastal erosion problems and the design of coastal protection schemes; stabilization of tidal inlets, lagoons and estuaries; and shallow water wave modeling.

1. The sea level is rising 2. The risk of floods increases

3. The sea level rises, river discharges increase and the soil is subsiding 4. Precipitation in winter increases

Solutions:

Water management and monitoring program with a solid institutional base High-tech monitoring tools and methods Specialized software and tools

8 Flood Control
Providing protection against sea and river water by means of dunes, levees and canals. Protection may require embankment and reinforcement of levees, building water control structures or installing high capacity pump stations. Sometimes protection requires additional space for water in places where this is possible.

The Dutch have been constructing levees and flood control structures for many centuries and may be viewed as some of the best experts in planning, design, construction and maintenance of levees and flood control structures. In addition, through extensive studies and experience, we are specialists in failure-mechanics. By using specialized software and assessment techniques, we can predict potential levee failures. Levee reinforcement can be achieved with regular use of sediment, but the Dutch have also developed innovative techniques to strengthen levees which are located in urban areas were little space exists: sheet piles, mixed in place, expanding columns, nails in levees, automated counterbalance, flood relief drain. The Dutch have built one of the worlds most impressive flood protection structures under very challenging environmental conditions. We offer expertise and highly specialized equipment in the design and construction of such structures. The Dutch coast is unique in the world in using soft measures to prevent the coast line from declining. We offer expertise in this kind of no-regret measures. Dutch companies can also design and provide high capacity pumps.

The Deltaworks: The Deltaworks, established after the 1953 floods to protect Zeeland, the worlds largest flood protection works, include the following: the Eastern Scheldt Barrier, a movable storm surge barrier, was constructed to protect against the sea without damaging the unique ecology of this estuary. The construction of 10250 miles of levees (1500 miles of primary levees and 8750 miles of secondary levees) along with 300 structures in main dikes. In addition, 13 estuaries were closed along with 1 inland estuary having several dams. Approximately 1650 sq km of land were reclaimed from the sea. International: Design and project management of the St Petersburg Storm Surge Barrier in Russia. Dutch engineers and contractors have also been recently involved with the construction of the famous Palm Island in Dubai, United Arab Emirates.

9 Flood Planning
Flood planning is the framework to transform the flood defense philosophy into a sustainable flood management system. The framework reveals the information and measures that need to be taken; as well as where and how it must be implemented.

The Dutch have developed several innovative data systems to gather information continuously on the strength of their levees by using remote sensing, fiber glass optics and GIS modeling. Responsibilities for flood management from different government levels are legally embedded in our policies. Provinces are responsible for authorizing procedures and for safety and spatial planning aspects of flood management. Consequently, they have a lot of experience in flood planning. The Dutch have a long tradition in urban and environmental planning, from national to local levels, which is scientifically praised world wide. Flood management plans are formulated with a scope duration of 50-100 and even up to 200 years.

10 Environmental Aspects of Flood Control

The design, construction and maintenance of flood control systems is not just a technical matter. There are many stakeholders! Environmental aspects include ecology, culture, landscape, archeology, recreation & tourism, water quality and geomorphology.

The Netherlands is a very densely populated country, with many stakeholders. With generations of experience in combining functions, the Dutch have developed expertise ensure integrated solutions. Specialized knowledge includes:

Strategic Environmental Assessments for large coastal and floodplain projects Environmental Impact Assessments for levees, coasts and structures

Structured combination of flood control improvements with improvement of environmental quality (quality of local life) A major advantage of these strategies is public support.

SEA for the improvement of the North Netherlands coast Nature compensation for all lost valuable nature due to levee construction/ strengthening EISs for levee and coastal reinforcements, both urban and rural

11 Risk Management Approach

We are developing a new risk management approach that includes determining how far the government can and should go in providing protection against high water levels and how much it can and should spend for that purpose. We will base the approach on factors including the "Safe Netherlands Roadmap". In that project, the Ministry has joined forces with provincial governments and water boards to gauge the likelihood and consequences of flooding in each levee ring (an area that is completely surrounded by levees).

The consequences of flooding are also taken into account in the Dutch risk management approach. Human and economic values also determine risk standards. Which means that not just technical expertise on dealing with flood management is needed, but also socio-economic experience. We support the decision-making process by providing scenarios, alternatives and public relations advise.

The Netherlands is divided into compartments with different risk levels of flooding. High density areas with greater human and economic interest, like Rotterdam and Amsterdam, are surrounded with stronger levees than rural areas and therefore have a lower risk level from flooding than others. One of the most difficult policy decisions for the Dutch in the next decade is to decide what level of protection is necessary, acceptable and cost-effective for each compartment.

12 Crisis Management & Reconstruction

Crisis management is needed to decrease the chance of damage and casualties in the case of a flood. Unnecessary or unsuccessful evacuations can be prevented by applying flood calculations and evacuation scenarios during the planning phase.

Development of contingency plans, evacuation plans and scenarios Public awareness of risks and evacuation routes

Development of decision making models to improve the evacuation process before and during a flood Advanced 3D flood modeling Flood risk mapping 24 hour monitoring and prediction of river levels

Dutch companies can offer comprehensive expertise for reconstruction: pumping, cleaning, building, infrastructure

ESCAPE: development program resulted in a model for contingency plans, a public awareness model, high water level information system model and a decision support system for evacuations Every Dutch municipality has an evacuation plan for its inhabitants Every water board has a contingency plan Automated Manual adresses high-water levels

13 Other relevant expertise

Dredging
We have some of the worlds leading companies in dredging. Dredging is an important corrective measure for our rivers. Dredging is also used to win sand for dune and beach maintenance and restoration. Dutch companies are working all around the world. Well known projects where Dutch engineers and contractors are working, are the palm tree and world islands in Dubai, United Arab Emirates.

Science & Technology

Water related science & technology is at a high level in The Netherlands. Public and private sectors cooperate in the development of new technologies. Universities like the University of Delft and the University of Wageningen have a rich tradition in high level water oriented education from hydraulic engineering to disaster studies and integrated water resource management.

Dura Vermeer is an entrepreneur rather than a contractor The complete handling of a project, sustainable construction methods, public private joint ventures, bearing risks...In effect, all of these terms basically imply that Dura Vermeer is an entrepreneur than a contractor. We have an increasingly broad responsibility in our main disciplines, i.e. infrastructure and construction. The era of

Dura Vermeer

merely executing strictly defined tasks is definitely over. These days, you can expect more from us, a lot more. Where capability is self-evident, know-how is increasingly important The world around us is changing very rapidly, and do is the part that we can and want to play in this world.

Major concerns and developments in technology and environment, spatial development, mobility and infrastructure increasingly appeal to our know-how and creativity. Where capability has become slef-evident due to standardization, know how is increasingly an important added value. A complete project, management and development organization Dura Vermeer has therefore transformed itself into a mulit-disciplinary integrator within a relatively short time. The service package now covers the total spectrum of disciplines required in infrastructure and construction, organized in an efficient and flexible manner. We aspire to become a leader in our markets and to consistently demonstrate our innovative strengths, with a new look on current topics, new forms of service, new products, and new technologies. Knowing that co-operation often leads to the best possible solutions, we continuously look for new forms and set-ups and ideal partners for this purpose. And as the compexity of problems increases, so does the need for simplicity in organization and the need to concentrate responsibilities. Dura Vermeer increasingly assumes the responsibility for the complete development, implementation and operation in one-on-one situations.
