HOUSTON, we’ve got a problem: Introduction program case Houston Galveston Bay Region, Texas (USA)
No full textVarious interesting tools were used and/or developed to stimulate knowledge integration in the Multifunctional Flood Defenses program. This chapter will present a diverse collection of these tools, hopefully stimulating others to consider using some of them in future.Spatial Planning and StrategyRivers, Ports, Waterways and Dredging Engineerin
Everything is bigger in Texas: Reflection program case ‘Houston Galveston Bay, Texas’
No full textThe saying goes that ‘Everything is bigger in Texas.’ This holds true for both the flood risk in the Houston-Galveston Bay Area, and for the complexity of issues that need to be dealt with in order to reduce it – assuming there is agreement that the current risk is unacceptable. There is currently no formal direction, and hence no preferred direction for designing a strategy for flood risk reduction Spatial Planning and StrategyHydraulic Structures and Flood Ris
Rotterdam roof park: A multifunctional structure of shared use: Defining four spatial dimensions of multifunctionality
No full textIn the context of urban planning, concepts of multiple land-use refer to situations were the existing space is more intensively used (Habiforum, cited in Hooimeijer et al, 2001). This can be achieved by morphological integration of functions (stacking of multiple functions in one building or construction), by mixed space use (multiple functions in a certain defined area) and by temporal shared-use of the same space.

A multifunctional answer to multiple questions: EPILOGUE
No full textWhen the MFFD program took off in 2012, its general goal was to gain a deeper understanding of multifunctional flood defenses, in order to provide a solid foundation for their design, assessment and management. As a point of departure, it assumed that a new generation of explicitly multifunctional flood defenses was the product of a need to accommodate competing spatial claims, and, perhaps, contribute financial savings by combining functions. Flagship projects like the Scheveningen Boulevard and Katwijk’s ‘hybrid’ parking garage complement an older generation of multifunctional flood defenses, the traditional example being dikes with sheep grazing or a road on top. The contemporary multifunctional flood defense was viewed as a complex but desirable phenomenon: the answer to multiple needs, and therefore best studied from a multidisciplinary perspective.

A city park on top of shops and a dike
No full textThe Roof Park ('Dakpark’) is an elevated park on a former railway yard in the Delfshaven quarter in Rotterdam. The park is located on top of the roof of a new shopping centre, which includes a parking garage (hence its name, ‘dak’ means ‘roof’). The park is the largest green roof in Rotterdam and one of the largest in the Netherlands. The park offers a playground, communal garden and a Mediterranean garden with an orangery (figure 9). The Roof Park is 1,000 m long and 80 m wide. The park is situated 9 m above street level. There is 25,000 m2 retail spaces under the city park, and the structure includes a car park with space for about 750 cars. The gardens bring more nature to the district, and the project as a whole has provided more employment. The Roof Park is combined with a dike, the ‘Delflandse Dijk’, that is part of dike ring 14, which protects the urban area of the Randstad. OLD Urban CompositionsHydraulic Structures and Flood Ris
Conceptualizing flexibility for multifunctional flood defenses
No full textThe very existence of the Netherlands and its prosperity is tightly linked to the provision of sufficient and reliable flood protection. Flood risk can change, as it is influenced by continually changing environmental and socio-economic factors. In such a dynamic situation, maintaining sufficient safety requires continuous investment in maintenance and reinforcement of the flood defenses. Often, flood defense reinforcement requires more space, which is scarce in densely populated urban areas. While the competing needs of housing, commerce, transportation, and agriculture have to fit in a relatively small surface area in the Netherlands, the safety of the living environment and the quality of the landscape have to be maintained as well. One way that has been suggested to deal with the conflict between flood protection and urbanization is by combining activities in the available space. This can be achieved by integrating urban functions into the flood defenses; these are referred to as multifunctional flood defenses. Hydraulic Structures and Flood Ris
Structural evaluation of multifunctional flood defenses
No full textFlood risk reduction aims to minimize losses in low-lying areas. One of the ways to reduce flood risks is to protect land by means of flood defenses. The Netherlands has a long tradition of flood protection and, therefore, a wide variety of technical reports written and guidelines developed for designing and assessing typical flood defenses. These documents have been prepared by the Dutch Technical Advisory Committee for the Flood Defenses (Technische Adviescommissie voor de Waterkeringen, TAW) and apply to dunes, lower and upper river dikes, lake and sea dikes, water-retaining hydraulic structures, etc. These documents contain methods and criteria to determine the reliability of flood defenses, based on the present state of technology and research.

Levees in a changing environment: Synchronizing and anticipating local challenges
No full textIn recent years, spatial planning and flood risk management (FRM) have been further coupled, thuscreating opportunities to incorporate water management measures in urban construction/reconstructionand landscaping. In addition, it is essential to find more than just technicalsolutions to potential flooding problems, and look for strategies that also addressgovernance, funding and more integrated design processes. Research in recent yearshas identified two dominant strategies - synchronization and anticipation -based on the question whether there is a flood risk issue and/or a spatialdevelopment plan and on the degree to which a flexible approach is available thatwill allow separate developments to be synchronized. These strategies can be usedin both urban and rural areas. Policy Analysi
Case Study: Katwijk aan Zee: Performance analysis of a multifunctional flood defense
No full textKatwijk is a small coastal town located at the old mouth of the River Rhine and along the North Sea. The national flood safety inspection of the coastal area demonstrated the need for the construction of a new sea dike to protect some 4000 people living in the city centre. The dune-covered coastline near the town is a tourist area that lacks sufficient car parking. To make best use of space and funds, the municipality and coastal authorities decided to combine functions and use the dune-area for both flood protection and parking. As this was a first-time project, it was yet unknown how interdepencies of functions would affect the performance of this multifunctional flood defense. In this research project we customized an existing performance analysis method to look into this issue. Hydraulic Structures and Flood Ris
Struggles and joy of multidisciplinary collaboration: program cases in the MFFD research program
No full textDesigning multifunctional flood defenses requires the input of knowledge from multiple disciplines, as has been frequently mentioned in this book. Researchers from multiple disciplines were employed in the MFFD-program, and they almost universally expressed a keen desire to collaborate. Different ways of collaboration were tried, explored, worked out; some were discarded as less useful, while others developed into useful products (see for example the 'MFFD-decisions' LEGO©-game and the 'Wind-turbines-on-dike' Electro©-game; p. 133).Rivers, Ports, Waterways and Dredging Engineerin
