The Design

About Hydro Buundo

Hydro-Bridge waa xarun gaadiidka kaladuwan oo ku dul marta Webiga Nakkhu ee Chyasikot, Nepal. Waxay la qabsataa isbedelada xilliga, waxayna u shaqeysaa sidii buundo lugooleyaal iyo baabuur khafiif ah bishaha qalalan, waxayna isu bedeshaa nidaam kaydin biyo iyo xero ammaan leh inta lagu jiro xilliga roobabka. Iyadoo isku dareysa kaabayaasha dhismaha iyo meesha dadweynaha, naqshadeynta waxay mudnaanta siisaa adkaysiga deegaanka, joogteynta, iyo baahiyaha bulshada iyadoo la jaan-qaadaysa muuqaalka dabiiciga ah.

Unique Properties: Hydro-Bridge is an adaptive, multifunctional pedestrain bridge in Chyasikot, Nepal. Designed to address the region's seasonal changes, it serves as a pedestrian and light vehicle bridge during dry periods and transforms into a water storage system and secure camping site during the rainy season. Its unique design merges public space and infrastructure, integrating environmental adaptation, sustainability, and community functionality, all while emphasizing harmony with the natural landscape.
Dimensions & Packaging: The bridge is 7m tall and 8m wide.
Tags: bridge, infrastructure, sustainable design, climate change
Production Technology: Steel structure with metal detailing and glass roof collecting rain water. Parametric design tools are used to design the bridge.
Design Challenge: The biggest challenge was designing a structure that responds to both community needs and the natural environment. Overcoming the constraints of budget, materials, and complex seasonal dynamics required interdisciplinary collaboration between architects, engineers, and hydrologists. The need to balance aesthetics with functionality, and to create a design that could withstand Nepal's intense monsoon season, while still offering public utility in drier months, pushed the creative boundaries and led to innovative structural solutions.
Research: The research behind Hydro-Bridge focused on sustainable infrastructure in flood-prone areas. The objective was to explore how built environments could adapt to climate conditions. The methodology involved site analysis, climate modeling, and user behavior studies, combining environmental data with structural analysis. Results showed the need for dual-purpose infrastructure that provides public space and addresses seasonal needs. This research highlights the bridge’s capacity to support urban resilience while fostering sustainable social spaces.
Inspiration: The inspiration came from the need to develop resilient infrastructure in regions prone to drastic weather shifts. Nepal’s monsoon seasons present significant challenges, which inspired the bridge’s dual function as a dry-season bridge and a rainy-season water storage solution. Drawing from the fluidity of natural water systems and vernacular architecture, the project offers a public space that embraces the rhythms of its environment and creates opportunities for social engagement.
Project Duration: Project is located Nakkhu River in Chyasikot, Nepal. First conceived in 2019.
Operation Flow: Hydro-Bridge operates dynamically based on the seasonal cycle. During the dry season, it functions as a bridge for pedestrians and light vehicles. As monsoon rains begin, it transforms into a system that captures and stores rainwater. The design allows people to interact with the structure, using it as a social hub while benefiting from its adaptable functionality. Its design provides seamless transitions, reflecting an intelligent response to environmental changes and offering a public space that supports community interaction.
