After a close shave with nature 20 years ago, the Netherlands has sought to reinvent defensive flood prevention. "Room for the Waal" is an anti-flood program in Nijmegen, a city which spans the River Waal, Europe’s busiest waterway, where a sharp turn forms a bottleneck as it nears the city. In 1995, heavy rains in upstream France and Germany caused an upsurge in water levels in Nijmegen that threatened to breach the dikes, warranting the evacuation of the city’s 170,000 residents, as well as cattle. Despite a crisis averted, the city is undertaking a flood resilience initiative focused on widening the floodplain rather than hedging its bets with fortified embankments. Through this floodplain, excavators will carve a new channel for the River Waal, leaving an island at its center. For starters, the dikes will recede 1,148 feet inland, and the resulting widened floodplains will be excavated to create room for a new channel. The island that is left behind presents an opportunity to construct a whole new section of city along with a unique urban river park, thus creating a two-fold tool for urban regeneration and flood deterrence. At certain points, the island is at a sufficient elevation for this purpose. The city is building four new bridges to connect the new island to both sides of the river, while a new neighborhood is rising across the river from the city center, balancing urban development on both sides of the waterway. Existing floodplains along the River Waal consist mostly of agricultural land, but 50 families in the village of Lent will need to relocate nevertheless in order to accommodate the receded embankments. Room for the Waal is part of national flood prevention program "Room for the River," into which the Dutch government is investing 2.3 billion euros (nearly $2.6 billion) on more than 30 crucial river locations to protect four million people who live on flood-prone territory. The approach consists of broadening and deepening floodplains and removing groins that obstruct water flow. Room for the Waal is expected to complete at the end of this year with a final cost of $381.6 million.

This solar-power generating bike lane in the Netherlands wows engineers by producing more juice than expected
Performance-wise, the Dutch power-generating bike path, SolaRoad, has overshot expectations, generating upwards of 3,000 kilowatts of power in the six months since its launch. The 230-foot concrete strip is located in Krommenie, a village northwest of Amsterdam, and is undergoing a three-year pilot test for material feasibility. The wattage generated in the first six months, according to SolaRoad, suffices to power a one-person household for a whole year. Based on this track record, the bike path is expected to generate 70 kilowatt hours per square meter per year (approximately 22,189 kilowatt hours per square meter per year), close to the upper limit predicted in lab tests. “We did not expect a yield as high as this so quickly,” Sten De Wit, spokesman for SolaRoad, said in a statement. The surprisingly inconspicuous solar panels are embedded into the concrete paving like ceramic tiling. Each panel is protected by an 0.4-inch layer of transparent, skid-resistant tempered safety glass designed to withstand the weight of passing vehicles. The pilot test itself will gauge the skid resistance of the solar panel path as compared to asphalt, and to ensure that it does not create any distracting reflections. Over 150,000 cyclists have reportedly traversed the solar-generating part of the path. According to SolaRoad, they “hardly notice it is a special path.” However, tests have shown that significant temperature fluctuations cause the glass coating to shrink, so that parts of it peel away in the winter and early spring. The coating has since been repaired, and engineers are in the “advanced stage” of developing an improved top layer. The 3-year pilot project, costing around $3.8 million, is a public-private partnership between the Dutch province of Noord Hoolland and engineering firms TNO, Ooms Civiel, and Imtech. Closer to home, Idaho inventors Scott and Julie Brusaw have their own iteration of power-generating roads, called Solar Roadways. The Brusaws are building a prototype parking lot in their headquarters featuring 108 panels to test their efficacy in the face of vehicle-imposed wear-and-tear. The hexagonal panels are designed for roads, driveways, parking lots, bike trails, and eventually, highways, and have already courted $850,000 in seed funding from the federal government and an additional $2 million from crowdfunding website Indiegogo.
The Harvard Graduate School of Design has announced the three potential awardees of the 2015 Wheelwright Prize, a travel-based architectural research grant valued at $100,000. Each year, one architect from approximately 200 applicants bags the prize. Established in 1935 at a time when foreign travel was limited to an elite few and then known as the Arthur C. Wheelwright Traveling Fellowship, the prize used to be awarded solely to GSD alumni. It has now become an international competition welcoming early-career architects (within 15 years of earning an architectural degree) from around the world to bring in new blood, fresh ideas, and cross-cultural exchange. The number of countries represented has grown from 46 the previous year to 51 this year, including Bosnia, Cuba, Egypt, Iran, Kazakhstan, Morocco, Poland, Sri Lanka, Ukraine, Zimbabwe and more. The seven-person jury of architects has selected three finalists to present their research proposals at the Harvard Graduate School of Design on April 16, with the winner to be announced at the end of the month. To inspire the next generation of Wheelwright prizewinners, the winner of the 2013 Wheelwright Prize, Gia Wolff, will present "Floating City: The Community-Based Architecture of Parade Floats," reporting on her research on over the past two years on carnival festivals. "The idea is not just about travel—the act of going and seeing the world—but it is about binding the idea of geography to themes and issues that hold great potential relevance to contemporary practice," said Harvard GSD Dean Mohsen Mostafavi in a statement. The three 2015 finalists are as follows: Erik L’Heureux, Assistant Professor at the National University of Singapore, presenting: “Hot and Wet: The Equatorial City and the Architectures of Atmosphere.” Malkit Shoshan, founder of think tank, FAST (Foundation for Achieving Seamless Territory) Amsterdam, presenting: “Architecture and Conflict: Pre-Cycling the Compound” Quynh Vantu, Award-winning Architect, London, presenting : “On Movement: The Threshold and its Shaping of Culture and Spatial Experience.”
Glimpses of New York and Amsterdam in 2040 at the Center for Architecture (through September 10) is a clarion call for designers to redefine sustainability in architecture. Though it didn’t start with this intention, the visions of 10 young architecture firms imagining future landscapes of New York and Amsterdam raise questions about what changes are imminent for urban development and what part architects can play. The projects suggest both practical and fantastical interventions to improve the prospect of urban growth in the face of ecological, geographic, and demographic shifts. The program comes hot on the heels of the announcements of Vision 2020: New York City Comprehensive Waterfront Plan and the similar strategy-based Structural Vision: Amsterdam 2040. Curators Luc Vrolijks, Rosamond Fletcher, and Marlies Buurman’s collective ambition has been to use design and debate to link the two cities in the context of these new directives. This month, the Center for Architecture hosted a series of talks and presentations of the work by the architects and the exhibit is also at the ARCAM site in Amsterdam until August 13, which will raise new questions about potential futures. The projects responded to one of five headings: Breathing, Eating, Making, Moving, Dwelling. Breathing: Both Delva with Dingeman Deijs and W Architecture and Landscape Architecture take water as their starting point. While Delva takes the IJ estuary as a generator for energy, W Architecture’s Hudson archepelagos, made using dredge from the port, provide habitats as well as landing banks. Eating: Here, WORKac focuses on the ‘food desert’ in the Bed-Stuy and Bushwick neighborhoods of Brooklyn and maps the potentially resourceful ways of re-appropriating the streets to harvest food, from future transportation (gondola-type links) to a hybrid fish farm and greenhouse-grown plants (Aquaponics). Van Bergen Kolpa Architects imagines a Landscape Supermarket, where varieties of food can be grown and sourced in park-like environments run by city dwellers. Making: In The Refinery, Solid Objectives-Idenburg Liu (SO-IL) imagined a floating market place where robotic arms compartmentalise waste materials to mend a broken landscape. Barcode Architects on the other hand has developed a contained mega science park from which to export knowledge - “the most valuable commodity of The Netherlands in 2040” said Caro van der Venne of Barcode. Moving: Dlandstudio responds to the future need for water transportation and how this can be an opportunity to also positively affect public wellbeing as well as environmental health. Fabric’s interpretation considers a new urban fabric based on mixing uses to produce “a more complete urban program, so that our daily needs are always near.” Dwelling: The Newark Visionary Museum by Interboro Partners and Space & Matter’s We is the New I both approached the idea of sustainability as social concerns. Interboro’s projection showed a colourful scene of failed plans and possible future solutions to Broad Street’s transportation, entertainment, sports and communication demands. Similarly practical was Space & Matter’s solution to increasing diversity and social cohesion by harnessing and building around common interests.
