China flood 20131/16/2024 ![]() Gravel pathways, bioswales, and tree planters also increase groundwater recharge. These terraces filter and clean the runoff. When inundations occur, these areas are fertilised by the incoming flow and silt deposits.ĭuring non-flooding periods, stormwater from the upper levels of the park cascades into the river. These landscaping strategies have increased fauna onsite, drawn to new habitats and clean water.įlood-tolerant wetlands along the terraced embankments enable water absorption, and provide a buffer for higher ground. All combined, the total surface area of the park is now 100% permeable, and covered with more than 12 plant species. On higher ground, the park is more formal, with pathways and pavilions set around a pattern of circular bioswales and green pockets. Retaining what was left of the wetlands, YP has enhanced and expanded the riparian edges of the site, using the existing sand quarries to create a micro terrain. In the process, a riparian ecosystem and public attraction were created, the latter thriving on proximity to Nature and the spectacle of seasonal floods. In YP, Yu has used landscape strategies to limit flooding. ![]() ![]() His mantra making friends with the flood ushered out hard-edged embankments, once seen as the only way to contain inundation. This park is exemplary of China’s Sponge City policy, a brainchild of Yu Kongjian, YP’s lead designer. With its wetlands restored, Yanweizhou Park has become a sponge, drawing flood waters into the ground. They bifurcate and swirl down into the landscape, taking visitors to the water’s edge. A little to the east, a new pond was created, and the bridges were put in place to link YP to the city. This area has become a sponge, drawing flood waters into the ground. The wetlands here were restored, while riparian edges and habitats were added. The low-lying part of the site had been degraded over time by sand quarrying and was largely undeveloped. Its form consists of a sprawling network of elevated pedestrian bridges emanating from a triangular patch of green. Completed in 2014, the park is sited on a 26 ha peninsula where the Wuyi and Yiwu Rivers converge to become the Jinhua River. Yanweizhou Park (YP) was designed to address these failings. However, being poorly connected to existing urban networks, it did not live up to the promise of revitalising the centre. The Opera House that was built in 2013, at the confluence of the city’s rivers, offered a new civic space. This aggravates conditions in an already crowded urban centre where social space has become a luxury, after years of intense densification. The annual monsoon often floods the banks of rivers in Jinhua City, located in eastern China. The book traces their rationale and impact, and demonstrates how each project can simultaneously benefit natural and human systems. Yanweizhou Park is one of 16 projects featured that actively repair and regenerate.
