Hello, I am Walter Lam Chun Hung, a final-year student pursuing a Bachelor of Arts (Honours) in Landscape Architecture at the Technological and Higher Education Institute of Hong Kong (THEi). My design focus lies in sustainable urban development, blue-green infrastructure, and the integration of ecological restoration with public spaces. Through my graduation project, I am dedicated to exploring how nature-based solutions can revitalize rigid urban infrastructures, transforming them into resilient socio-ecological systems that harmoniously reconnect local communities with their natural water environments.
“Rewilding the Urban River” reimagines the 4-kilometer Tuen Mun River as a continuous socio-ecological corridor from Siu Hong to Castle Peak Bay. Addressing persistent hydrological degradation and social disconnection, this project proposes a holistic, nature-based revitalisation strategy. It features upstream constructed wetlands to filter rural pollution, a mid-reach urban water plaza to reconnect residents with the waterfront, and a formalised, accessible harbour edge for boating and recreation. Ultimately, the design transforms a concretised drainage channel into a vibrant blue-green infrastructure that harmonises flood safety, ecological recovery, and community well-being.
「城市河流野化」旨在將長約4公里的屯門河（由兆康延伸至青山灣）重新塑造成一條連續的社會生態走廊 。面對屯門河長期以來的水文退化與社區空間疏離，本設計採用「基於自然的解決方案」（NBS），提出一項全走廊尺度的活化策略 。 項目針對三大河段進行改造：上游引入人工濕地與自然河岸，以過濾非點源污染並修復水文生境 ；中游於市中心打造「城市水畔廣場」，設置親水階梯以重新連結市民與水岸空間，以供休閒娛樂與節慶活動之用 ；下游將會重塑避風塘邊緣空間，增設安全浮橋與階梯式海堤，在兼顧避風塘用途的同時對公眾開放海濱 。 本方案在嚴格維持防洪標準的前提下，將單一的混凝土排水道轉化為充滿活力的藍綠基礎設施，為香港城市河流的生態修復與社會轉型提供了一個具前瞻性的示範藍圖 。
