In response to the pressing challenges posed by rapid urbanization, this thesis critically explores the efficacy of blue-green infrastructure (BGI) as a sustainable approach to urban stormwater management. The expansion of urban areas has significantly increased the prevalence of impermeable surfaces, exacerbating issues such as flooding and pollution. Traditional grey infrastructure, while vital, often inadequately addresses these complex environmental concerns. Against this backdrop, BGI presents an innovative solution, integrating water management with green space to utilize natural processes for stormwater treatment, thereby aiming to enhance urban resilience, biodiversity, and socio-economic well-being. This research focuses on the application of the Storm Water Management Model (SWMM) to simulate rainfall-runoff scenarios in Bellinge, Denmark—a suburban area embodying the urban-rural interface's unique stormwater management challenges. The study aims to develop a detailed stormwater management model incorporating BGI and assess its impact on improving hydrological parameters and urban livability. Employing a structured methodology, the thesis begins with a comprehensive literature review to contextualize BGI within current stormwater management practices. An in-depth analysis of Bellinge follows, examining its environmental, socio-economic, and infrastructural characteristics to pinpoint specific challenges and opportunities for BGI. The research then progresses to the development and application of a stormwater management model for Bellinge using SWMM, integrating BGI components tailored to the area's unique context. By conducting simulations and analyzing outcomes, the study seeks to validate the theoretical benefits of BGI, offering empirical evidence of its potential to mitigate stormwater issues effectively. This approach not only quantifies the impact of BGI on key hydrological parameters but also highlights the importance of context-specific planning and implementation in realizing its full benefits. Ultimately, this thesis aims to bridge the gap between theoretical support for BGI and its practical application in stormwater management, advocating for its broader integration into urban planning as a resilient and sustainable solution to contemporary environmental challenges. Through a meticulous exploration of BGI's multifaceted benefits, the research contributes to a deeper understanding of its role in fostering sustainable urban development.
In risposta alle sfide urgenti poste dall'urbanizzazione rapida, questa tesi esplora criticamente l'efficacia delle infrastrutture blu-verdi (BGI) come approccio sostenibile alla gestione delle acque piovane urbane. L'espansione delle aree urbane ha notevolmente aumentato la prevalenza di superfici impermeabili, esacerbando problemi quali allagamenti e inquinamento. L'infrastruttura grigia tradizionale, sebbene vitale, spesso non affronta adeguatamente queste complesse preoccupazioni ambientali. In questo contesto, le BGI presentano una soluzione innovativa, integrando la gestione dell'acqua con la pianificazione degli spazi verdi per utilizzare i processi naturali per il trattamento delle acque piovane, mirando così a migliorare la resilienza urbana, la biodiversità e il benessere socio-economico. Questa ricerca si concentra sull'applicazione del Modello di Gestione delle Acque Piovane (SWMM) per simulare scenari di deflusso delle piogge a Bellinge, Danimarca, un'area suburbana che incarna le sfide uniche di gestione delle acque piovane dell'interfaccia urbano-rurale. Lo studio mira a sviluppare un modello dettagliato di gestione delle acque piovane incorporando le BGI e valutarne l'impatto sul miglioramento dei parametri idrologici e della vivibilità urbana. Impiegando una metodologia strutturata, la tesi inizia con una revisione della letteratura completa per contestualizzare le BGI nelle attuali pratiche di gestione delle acque piovane. Segue un'analisi approfondita di Bellinge, esaminando le sue caratteristiche ambientali, socio-economiche e infrastrutturali per individuare specifiche sfide e opportunità per le BGI. La ricerca procede poi allo sviluppo e all'applicazione di un modello di gestione delle acque piovane per Bellinge usando il SWMM, integrando componenti BGI su misura per il contesto unico dell'area. Conducendo simulazioni e analizzando i risultati, lo studio cerca di validare i benefici teorici delle BGI, offrendo prove empiriche del loro potenziale per mitigare efficacemente i problemi delle acque piovane. Questo approccio non solo quantifica l'impatto delle BGI sui principali parametri idrologici, ma evidenzia anche l'importanza della pianificazione e dell'implementazione specifiche per il contesto nel realizzare i suoi pieni benefici. In definitiva, questa tesi mira a colmare il divario tra il sostegno teorico per le BGI e la loro applicazione pratica nella gestione delle acque piovane, sostenendo la loro più ampia integrazione nella pianificazione urbana come soluzione resiliente e sostenibile alle sfide ambientali contemporanee. Attraverso un'esplorazione meticolosa dei benefici multifaccettati delle BGI, la ricerca contribuisce a una comprensione più profonda del loro ruolo nel favorire uno sviluppo urbano sostenibile.

Abstract
In response to the pressing challenges posed by rapid urbanization, this thesis critically explores the efficacy of blue-green infrastructure (BGI) as a sustainable approach to urban stormwater management. The expansion of urban areas has significantly increased the prevalence of impermeable surfaces, exacerbating issues such as flooding and pollution. Traditional grey infrastructure, while vital, often inadequately addresses these complex environmental concerns. Against this backdrop, BGI presents an innovative solution, integrating water management with green space to utilize natural processes for stormwater treatment, thereby aiming to enhance urban resilience, biodiversity, and socio-economic well-being. This research focuses on the application of the Storm Water Management Model (SWMM) to simulate rainfall-runoff scenarios in Bellinge, Denmark—a suburban area embodying the urban-rural interface's unique stormwater management challenges. The study aims to develop a detailed stormwater management model incorporating BGI and assess its impact on improving hydrological parameters and urban livability. Employing a structured methodology, the thesis begins with a comprehensive literature review to contextualize BGI within current stormwater management practices.
