💦 The thesis proposes a new 𝐇𝐲𝐝𝐫𝐨𝐬𝐨𝐜𝐢𝐚𝐥 𝐑𝐞𝐬𝐨𝐮𝐫𝐜𝐞 𝐔𝐫𝐛𝐚𝐧 𝐍𝐞𝐱𝐮𝐬 (𝐇𝐑𝐔𝐍)
framework, which conceptualises urban water management as a multilayer resource nexus linking water, energy, food, ecosystems and society.

♻️ 💻 Within the model, system infrastructure is defined by four design strategies: circularity, scale, greening and digitalisation. The framework sets out a planning cycle for circular interventions and assesses system performance through environmental and socioeconomic functionalities.

🏙️ Moreover, the thesis tests a spatial decision-support method in Girona, combining GIS-MCDA, graph-based clustering, risk indicators, socio-environmental criteria and stakeholder preferences.
