“…Other researcher defined that flood vulnerability as the degree of susceptibility to damage from the flood [12]. When flood physically attacks on people and infrastructure, then the vulnerability of people and infrastructure is based on the degree of harm and damage [13]. Since vulnerability is found to be the main reason of disasters, it seems necessary to develop the perception of the vulnerability [14].…”

Flood event is one of the natural disasters that increasingly threaten the safety of the people in an area. Critical infrastructure albeit important, has been shown to be vulnerable to flooding and damages to critical infrastructure element may affect large areas over a longer time period. Critical infrastructures play an important role in functioning of industries and communities and also responding against flooding to reduce their impacts. Critical infrastructures such as hospital, school, road networks and other infrastructures are important during flood event to serve as emergency services. It was found that there is difference in understanding the concept of vulnerability with varying assessments and different view. This paper briefly reviews the concept of vulnerability and discusses on the approach used for flood vulnerability of critical infrastructure by past researchers to identify and fortify the vulnerable critical infrastructure ahead of time reducing the potential damage due to flood. This paper focuses the vulnerability of critical infrastructure during flood event and also describes several approaches with a discussion on the application of the approaches used and the relevance results.

“…Detention reservoirs can reduce the peak discharge in urban drainage systems. It is difficult, however, to prevent flooding due to extreme rainfall, even though all drainage facilities are designed and constructed using the concept of design flood frequency [1]. Both structural and non-structural measures can be implemented to prevent and reduce flooding.…”

Failure of drainage systems leads to urban flooding; therefore, structural measures such as the installation of additional drainage facilities, including pump stations and detention reservoirs, have been adopted in the past to prevent and mitigate urban flooding. These measures, however, are costly and time consuming. To maximize flood mitigation efficiency, it is essential to also implement non-structural measures such as effective operation of drainage facilities. In this study, we propose a new cooperative operation scheme for urban drainage systems that involves linking centralized reservoir (CR) and decentralized reservoir (DR) operations by sharing water level information at monitoring nodes. Additionally, we develop a resilience index to assess the system's ability to mitigate, restore, and recover from inundation (i.e., failure). Most results show that flood reduction and resilience in cooperative operations are better than the current operation. However, the results of CR operation for 2010 are worse than the current operation at high monitoring node levels (1.4 m-1.5 m), and the results of DR operation for 2011 are worse than the current operation at low monitoring node levels (0.8 m-0.9 m). All results related to flood reduction and resilience in cooperative operation are superior to the current operation.

“…This growing urbanization is contributing to reduce the soil absorption capacity and storage of stormwater, which has lead, together with the ageing of the existing drainage infrastructure, to an increase in the cost of flood management (Wegehenkel and Kersebaum, 2008;Einfalt et al, 2009;Tingsanchali, 2012;Makropoulos et al, 2008). To tackle this challenge, innovative and sustainable urban drainage systems and methodologies are needed.…”

Energy recovery in SUDS towards smart water grids: A case study

An innovative solution for Sustainable Urban Drainage Systems (SUDS).Use of retention ponds to reduce risks of urban flooding while producing energy. Use of recently developed hydropower converters for low heads. Solution to be integrated in future smart water networks for increasing efficiency. Water and energy nexus for sustainable operation towards future smart cities. a r t i c l e i n f o a b s t r a c tThe development of a methodology for urban flood adaptation and energy recovery solutions is resting on the concept of Sustainable Urban Drainage Systems (SUDS) as a measure to reduce risks of urban flooding while fully utilizing the available resources. Flood drainage systems are infrastructures essential in urban areas, which include retention ponds that can be used as water storage volumes to damp floods and simultaneously to produce energy, constituting innovative solutions to be integrated in future smart water grid′s designs.The consideration of urban flooding as a problem caused by excess water that can be harvested and reused is expected to provide a comprehensive representation of a water-energy nexus for future urban areas. The study comprises an optimization of energy recovery in SUDS of a small district area of Lisbon down-town through the use of a low-head hydropower converter.The status-quo solution based on a basin catchment for the average expected runoff is analysed, with influence of the tidal backwater effect of the Atlantic Ocean which causes difficulties to the drainage of excess flow. The methodology used to reach the flow damping and the optimized solution for energy production is presented.
