Exemplary Research Transforming Urban Spaces

Case Study 1: Enhancing Urban Resilience to Coastal Flooding

This interdisciplinary project, involving researchers from HKU's Department of Urban Planning and Design and the Department of Civil Engineering, aimed to develop a integrated framework for assessing and mitigating coastal flood risk in Hong Kong's Victoria Harbour under future climate scenarios.

• Research Question: How will combined sea-level rise and more intense storm surges impact critical infrastructure and communities around Victoria Harbour, and what hybrid engineering-nature-based solutions can most effectively mitigate this risk?
• Methodology: The team employed high-resolution hydrodynamic modeling, geographic information systems (GIS) analysis of infrastructure vulnerability, and cost-benefit analysis of various adaptation measures, including traditional seawalls, revitalized mangrove belts, and oyster reef breakwaters.
• Findings: The models predicted that by 2050, without intervention, several billion dollars worth of infrastructure and tens of thousands of residents would be at significant risk. The research demonstrated that a hybrid approach, combining strategically placed seawalls with the restoration of natural coastal ecosystems, was not only more cost-effective but also provided co-benefits such as improved water quality and enhanced biodiversity.
• Real-World Impact: The findings were presented to the Drainage Services Department and have directly informed the ongoing "Harbourfront Enhancement" initiatives. Elements of the hybrid defense strategy are being incorporated into the planning for new coastal developments in Kai Tak and Wan Chai, making the city's waterfront more resilient and livable.

Case Study 2: Smart Solutions for Informal Public Transport

Conducted within a collaborative framework with Singapore's Nanyang Technological University, this research focused on Hong Kong's public light buses (minibuses), an essential but data-poor component of the city's transport network.

• Research Question: Can the application of IoT sensors and machine learning optimize the routing and scheduling of public light buses to improve service reliability, reduce waiting times, and increase overall system efficiency?
• Methodology: Researchers equipped a fleet of over 100 green minibuses with GPS and passenger-counting sensors. They collected several months of high-frequency data on vehicle locations, speeds, and passenger loads. Machine learning algorithms were then developed to predict demand patterns and simulate dynamic routing adjustments in real-time.
