Globally the catastrophic flooding events are increasing and these extreme events are attributed to climate change and anthropogenic influences. It has been observed that the cities in the arid and semiarid areas have frequently experienced severe flooding in the last two decades. Urban flooding is becoming a major issue in many megacities around the world due to a lack of adequate stormwater management, hydrologic design, and failure of aging hydrologic infrastructure. It is of utmost importance to model such extreme flood events to develop state-of-the-art disaster mitigation and damage reduction measures. This session invites presentations based on research related to one and two-dimensional hydrologic and coupled hydrodynamic modelling approaches. The research papers are expected to discuss various flood forecasting methods and measures required to mitigate urban floods. Lack of data availability and dissemination of impending extreme events are major issues of concern in many parts of the world. The encroachment in the flood plains and plugging off natural water ways in the urban centers aggravate flooding of cities. Innovative methods that can address the modelling of floods in the data scare regions are essential and works related to these issues are invited. Modelling and management of urban floods are a challenge and the presentations that address spatial and temporal complexity of such events using different methodologies are needed. The session is expected to discuss urban floods analysis and measures to mitigate the effects of these events, emerging (e.g., Internet-of-Things (IoT)-based) flood monitoring systems, as well as street-level flood forecasting. Dissemination of flood warnings and measures to evacuate people and case studies of such events are expected to provide a better understanding of urban flood management. Innovative methods of floodwater conservation, low impact development (LID) includes strategies and practices that are designed to control surface runoff at its sources in a sustainable way are emerging methodologies. This session will invite presenters who will address all the above issues.
