Yu Kongjian is the architect making friends with flooding

I had the opportunity to observe U in its natural habitat that evening. He led me and the gang through a set of carved metal doors to the club and across the courtyard, where the traditional stone structure was replaced with thick glass. Inside he led us down to a huge table under that transparent floor. As we sat in ornate, carved chairs drinking the juice of the shiny-green cucumber, I looked up at the moon above. The finance ministers were also visiting the club that evening, so U returned between our tables. Before we left, he gave me a souvenir: a heavy Tom title Designed Ecology: Landscape Architecture of Congenital UniAfter dinner, his driver drove us to my hotel in a brand new Mercedes minivan, where U went for a walk home તેનો his daily routine.

A week later I visited a project of Turenscape: Yongxing River Park, located in Dexing, a remote area of ​​Beijing. “Before” in satellite images from three years ago a river was bounded by straight and straight concrete walls. The “now” paintings were square-a-blocks with buildings surrounding the more generous, winding road for water.

The project was almost complete when I saw it. About two and a half miles long and perhaps two city blocks wide, the park follows the river. To widen the river bed, workers dug concrete and dug soil along the river bank. The dirt was then molded into a large burr running down the center, in which two channels were made. The river flows to one side; The second channel has large holes of different depths that act as filtration bridges. During the dry season, the filtration side is filled with wastewater that is partially cleaned from the wastewater treatment plant. Wetland plants in the pool make it more clean, and allow some water to be filtered underground at a slower pace. During the monsoon season, those channels are reserved for flood waters, and wastewater is treated industrially.

TURENSCAPE

The gang and I walked on a fragile concrete path over central Burma. Many of Turenscape’s designs have walkways like these, which are above the wetlands, so that people can enter the landscape all year round and appreciate the seasonal changes. Newly released huge river banks from concrete, scattered in thousands of small sages planted in closely set rows to hold the earth, like pointillist-render landscapes. We passed the young willow, an original streamside plant that can withstand flooding. Elsewhere, reeds, dwarf greenturf and other native plants stabilize the soil. Turenscape uses native plants mostly in its design as it thrives on available water, weather and nutrients.

In the summer of 2020, during the heavy summer rains, the U.S. sent me photos of Yongxing River Park. The trees and grass had grown significantly since I visited. There was a lot of water in the channel but it was not close to overtopping. Turenscape does not yet have data on Yongxing’s flood capacity, infiltration rate, or water-cleaning services, but the U.A. described its management of the monsoon that year as “excellent performance.”
