Urban flooding presents a significant challenge to cities worldwide, resulting in loss of life and economic damage. Factors such as urbanization, climate change, and extreme weather events compound the vulnerability of urban areas to flooding, with rapid urbanization emerging as a primary driver of increased flood risk. In response to this pressing issue, this thesis embarks on a transformative exploration, advocating for a paradigm shift in urban stormwater management through the lens of "Hydro-Urbanism." Central to this concept is recognizing stormwater as a valuable resource rather than a mere liability. By implementing targeted strategies to curb runoff, detain stormwater, and replenish groundwater, cities can mitigate the adverse impacts of urban flooding while enhancing resilience and livability. Through a comprehensive review of existing literature and analysis of case studies, this research explores the efficacy of diverse stormwater management techniques in alleviating urban flooding and fostering sustainable urban development. In addition to technical aspects, the study delves into the socioeconomic dimensions of Hydro-Urbanism, highlighting the significance of community engagement and participatory planning in creating resilient and inclusive urban environments. Focused on Hyderabad city in Telangana, India, this project lies at the intersection of cultural heritage and modernity, confronting significant challenges posed by urban flooding amidst rapid urban expansion. By reframing the narrative around water from vulnerability to resilience and opportunity, the project aims to harness the power of stormwater as a catalyst for change. A tailored typology-based approach seeks to nurture a future where cities and water coexist harmoniously, protecting urban areas from flooding and fostering a more harmonious relationship between urban communities and the natural world. / Master of Science / Urban flooding, characterized by the inundation of urban streets, buildings, and infrastructure, arises when rainwater overwhelms drainage systems or water bodies overflow due to heavy rainfall or storms. It is a significant challenge faced by cities globally, leading to property damage, transportation disruptions, and risks to public safety. In response to the pressing issue of urban flooding, this project adopts a novel approach called "Hydro-Urbanism," emphasizing the interconnection between water and urban landscapes and aiming to transform how cities manage stormwater resources. Unlike traditional methods that view stormwater as a problem to be mitigated, Hydro-Urbanism recognizes stormwater as a valuable resource that can be harnessed for various purposes. It seeks to establish a symbiotic relationship between urban environments and water, wherein stormwater is managed strategically to mitigate flooding risks and enhance urban resilience while improving the quality of urban life. Amid rapid urbanization, exemplified vividly in cities like Hyderabad in the Telangana state of India, the balance between expanding urban sprawl and natural ecosystems has become increasingly fragile. Here, the challenge of managing stormwater looms large, threatening public safety, infrastructure integrity, and economic stability. Nevertheless, what if we could flip this narrative? What if stormwater could be a resource instead of being a menace? Focused on Hyderabad, a city at the crossroads of tradition and modernity, this project proposes a typology-based approach tailored to its unique urban fabric. By harnessing the potential of stormwater, the project aims to pave the way for a more resilient and adaptive urban future. Ultimately, the goal is to foster a harmonious coexistence between urban communities and stormwater resources, ensuring cities' long-term viability and well-being in the face of environmental uncertainties.

This study addresses flood risk assessment in the Catalpa Creek watershed, located in northeast Mississippi, USA. Employing the Hydrological Modeling System (HEC-HMS) and the River Analysis System (HEC-RAS), integrated models were developed and calibrated, to predict flood behavior within the watershed. The study conducted flood frequency analyses for return periods ranging from 2 to 100 years and generated flood inundation maps, pinpointing flood-prone areas. Mitigation measures for flood risk management were recommended. The results underscore the effectiveness of the integrated modeling approach for simulating and understanding the complex dynamics of flood events. The research identified critical flood-prone zones, emphasizing the importance of proactive flood risk management. The calibrated hydrological model serves as a valuable tool for stormwater management, water resource planning, and watershed assessment. The study provides insights into flood risk in the Catalpa Creek watershed, offering valuable guidance to regional decision-makers. This study lays the foundation for future investigations in floodplain encroachment, sediment transport, stream restoration, and flood inundation hazard mapping.
