“…Their research, which uses Metro Manila as a case study, has shown how the rapid impact assessment matrix (RIAM) technique can be used to systematically and quantitatively evaluate both the socio-economic and environmental impacts of planned structural flood mitigation projects in highly urbanised areas. Furthermore, a recent study by Xian et al (2018) recommend minimising the environmental impact of flood mitigation measures by harmonising future flood protection designs with the surrounding environment and ecosystem. An example is the use of large-scale, nature-based protection such as marshes or wetlands as a means of minimising the impact of storm surge flooding (Xian et al 2018).…”

An example is the use of large-scale, nature-based protection such as marshes or wetlands as a means of minimising the impact of storm surge flooding (Xian et al 2018). This nature-based approach to flood mitigation provides societal and environmental benefits to the public, but its adoption in CMDN is constrained by the process of rapid urbanisation, which typically includes suppression of natural retention areas, removal of natural vegetation, and construction of large impervious areas .…”

“…Furthermore, a hydrodynamic modelling study by Takagi et al (2017), which aims to understand the long-term effectiveness of proposed dikes under continuing sea-level rise, tides and rapid land subsidence scenarios in Jakarta, shows that the effectiveness of using higher flood defence will gradually disappear over time. Xian et al (2018) raised concern that current flood mitigation measures need to be stepped up to account for the dynamics of future climate and sea level rise in coastal cities. They noted that dynamic sea walls with flexibility for incremental height increases in line with future increases in sea level, is preferable to the traditional design of sea walls with fixed heights.…”

“…Similarly, Daksiya et al (2017) carried out a comparative evaluation of six different flood levee construction plans for a central basin of Jakarta using a MultiCriteria Decision Analysis (MCDA) technique that takes into consideration flood extent estimates, cost of flood mitigation measures, and the social-economic impact of flooding on people. Findings from Yin et al (2015) and Xian et al (2018) suggest that in-depth decision making regarding priority-based selection of flood protection measures can be influenced by other factors, including flood return periods, institutional aspects of governance, topography, societal exposure, and experience with past extreme events.…”

Flooding is a major environmental problem around the world. The problem is expected to worsen with climate change, particularly in coastal megacities of developing nations (CMDN), where vulnerability to extreme weather events is high and flood management capacity is weak. This systematic literature review focuses on structural approaches to flood management in CMDN as most of these cities rely heavily on them. The review covers the last two decades, being the period 1998-2018. Results reveal key areas of research, which are discussed within two broad categories of focus (1) establishment of new flood control projects and (2) management of existing flood control infrastructure. Several directions are suggested to guide future research efforts.

“…Southeastern Texas received a significant amount of the damages: Over 300,000 structures were flooded and over 336,000 customers lost their power from the hurricane [1]. Harvey had an extraordinary amount of rainfall associated with the storm over the coastal regions of Texas Others have looked at community resilience and the coastal flooding [7][8][9][10][11] for Hurricane Sandy and other storms; however, in many of these studies they look at only the storm surge and wave influences in the coastal flooding. In particular, Lin et al [11] analyzed the coastal flooding caused by Hurricane Sandy and what impacts climate change would have had on the coastal flooding of the storm.…”

With a growing population (over 40%) living in coastal counties within the U.S., there is an increasing risk that coastal communities will be significantly impacted by riverine/coastal flooding and high winds associated with tropical cyclones. Climate change could exacerbate these risks; thus, it would be prudent for coastal communities to plan for resilience in the face of these uncertainties. In order to address all of these risks, a coupled physics-based modeling system has been developed that simulates total water levels. This system uses parametric models for both rainfall and wind, which only require essential information (e.g., track and central pressure) generated by a hurricane model. The system is validated with Hurricane Isabel hindcasts: One using the parametric system and another using data assimilated fields. The results show a good agreement to the available data, indicating that the system is able to adequately capture the hazards using parametric models, as compared to optimized fields. The validated system was then utilized to simulate randomly generated scenarios that account for future uncertainty, i.e., amount of sea level rise and storm strength/track, as influenced by projected climate change scenarios. Results are then used in next step in the development of a system-wide, community resilience model. with the Houston area experiencing approximately 36 to 48 inches total during the storm. As well, some of the cities along the Texas/Louisiana border received over 60 inches. All of the rain caused many of the rivers within the Houston metro areas to exceed their banks and lead to record flood stages on Clear Creek, Dickinson Bayou, Buffalo Bayou and Cypress Creek [1].Hurricane Irma followed Hurricane Harvey by a couple of weeks and made landfall in Florida. Similar to Harvey, Irma produced damages that were caused by wind and flooding due to both storm surge and rainfall. Irma affected the Florida Keys most significantly with almost 25% of the buildings on the Keys destroyed during the storm and almost 90% of the structures sustaining damage [2]. Throughout several counties of Florida, Irma destroyed structures and caused significant power failures. Furthermore, the storm had a devastating effect on the agricultural crops, e.g., it was estimated that approximately $760 million in damage was done to the orange groves in the southwestern and central parts of Florida [2]. Heavy rainfall occurred as Irma moved into the northern portions of Florida leading to significant flooding with rivers reaching, and some exceeding, previously recorded flood stages in nine different counties: Bradford, Clay, Marion, Flagler, Duval, Putnam, St. Johns, Nassau and Alachua [2].Hurricane Maria was the most devastating hurricane to make landfall on any of the Caribbean islands in almost 80 years. Reports from the island nation of Dominica indicated that a majority of the structures on the island were either seriously damaged or destroyed as a result of the storm. In fact, Pasch et al. [3] indicated that the Prime M...
