The interplay of colors in Lin's watercolor painting reflect the diversity of the riverside plants, which were grown carefully by the Ilan County Government based on concepts integrating flood control and ecological conservation.
Along the middle reaches of the 15km-long river, steep concrete embankments are being replaced by gentle slopes covered with riverside plants such as water willow (水柳), Leersia hexandra (李氏禾) and verdant grass. A scenic route along the meandering river in a 2.2km section between Ilan Bridge and Chungshan Bridge is now a haven for hikers, runners and bicycle riders.
"The river reconstruction project demonstrates that engineering within ecological constraints has helped people to live in harmony with nature," said Kuo Ching-chiang (
According to Kuo, the commission has been promoting ecological engineering in public construction since last year to preserve the natural heritage and improve resistance to floods.

The story began in 1997, when Premier Yu Shyi-kun, an Ilan native, served as county commissioner. Yu believed the promotion of tourism based on ecological preservation would greatly benefit the rural county. About 465,000 residents live on a broad plain covering 320km2 of land.
Having persuaded the Water Resources Agency and the Council of Agriculture's Soil and Water Conservation Bureau to adopt innovative, eco-friendly engineering methods based on concepts employed in Germany and Switzerland, the local authority turned the river into one of the finest examples of a symbiosis of ecological engineering and disaster prevention.
Yu returned to his hometown for the annual government-sponsored Ecotechnology Expo, which was held in Ilan last Saturday. The premier joined hundreds of residents, including agile youngsters and energetic senior people, on a bicycle ride along the newly-reconstructed river.
Later that evening, hundreds of Ilan residents and tourists sat on the green slopes of embankments, enjoying music performed by the Ilan Philharmonic Orchestra.
Yu said he was deeply moved by the residents' enthusiastic response, especially that of the younger people.
"It's important to make future generations aware of the advantages of eco-engineering and sustainable development," he said.
Well-designed public projects should be able to simultaneously achieve the goals of environmental protection, landscape preservation, eco-tourism and river reconstruction, he said.
Lee Chien-chuan (李健全), vice chairman of the Council of Agriculture, said the reconstruction of the river entailed 26 sub-contracts costing NT$130 million over the past two years, and has provided the public with safe access to the river.
New types of eco-friendly embankments were designed to suit the area following an investigation of its plant and animal life, as well as the physical and chemical environment.
