Urban flood control has become an important issue for both city planners and researchers as flood is one of the most severe natural disasters for large cities. Although many measures have been implemented for urban flood control, the effectiveness and efficiency is greatly hampered by the poor management of physical assets. In urban flood control, managing physical assets is challenging as it involves a complex asset base with the dispersion of asset allocations, management processes, and information systems. To address these challenges, this paper proposes an integrated asset management platform for urban flood control. Cloud technology is adopted to provide whole life cycle management of physical assets by integrating various management processes and information systems. It also enables the cooperative management between sectors. Besides, the concept of smart asset is introduced to realize remote management and real-time data collection from these assets. In the end, a case study is also given to demonstrate the working procedural of managing a typical smart asset through the proposed cloud platform.
