“…Sediment precipitation was observed due to the high load of silt, and the riverbed level increased annually, changing the capability of structural measures for flood mitigation (Figure 10). Understanding flood plain dynamics will assist in developing effective land management strategies [102]. This includes preserving the river's natural water spate areas and promoting ecologically sensitive land use activities [103,104].…”

Sediment precipitation in riverbeds influences the effectiveness of structural and non-structural measures for flash flood mitigation and increases the potential for flooding. This study aimed to disclose the effectiveness of the implemented measures for flood risk mitigation in Kassala town, eastern Sudan. We employed remote sensing (RS) and GIS techniques to determine the change in the Gash River riverbed, the morphology, and the leveling of both the eastern and western sides of the river. Flood model simulation and a 3D path profile were generated using the digital elevation model (DEM) with a data resolution of 12.5 m from the ALOS BILSAR satellite. The main purpose of this study is to extract the layer of elevation of the riverbed on both the western and eastern banks and to determine the variations and their relationship to flood occurrence and mitigation. The construction of dikes and spurs near Kassala town has led to sediment precipitation, causing the riverbed to rise. The results show that it is now 1.5 m above the eastern Kassala town level, with a steep slope of 2 m/km, and the cross-section area at Kassala bridge has shrunk, which indicates that the bridge body will partially impede the river’s high discharge and increase the potential for flood risk in the study area. The eastern part of Kassala town has a higher likelihood of flooding than the western side. This study suggests redesigning structural measures like widening the Gash River, extending Kassala bridge for normal water flow, strengthening early warning systems, and implementing soil conservation activities for normal water flow.

“…It advocates for ward level risk mapping and vulnerability assessment and setting up of urban flooding cell for integrated urban flood management at municipal level. In New Brunswick, Canada, the land use controls were even linked with flood risk mapping with different restrictions for high-and low-risk zones [37]. NDMA guidelines on management of urban flood offer many practical and innovative solutions such as rain gardens, detention ponds, and lined channels [38].…”

Flood Impact Mitigation and Resilience Enhancement

View full text Add to dashboard Cite

Cities are increasingly faced with frequent floods disrupting everyday lives. Adapting to flood risks and conserving eco-sensitive sites are central to social ecological resilience. Rapidly expanding cities are found short of mitigating the adverse environmental impacts. For enhancing flood resilience, it is important to understand the interaction of the key stakeholders and its impact on governance and land use in the cities. Land use change in urban space is constantly influenced by negotiations among various interest groups. The urban governance structures are increasingly dominated by neoliberal approaches of profit maximization. Following a heuristic framework for policy analysis of land use change and governance, the present study assesses the barriers in building flood resilient cities. We apply the framework to Hyderabad city of Telangana, India, which has faced the recurring challenge of flooding. Results demonstrate the lack of urgency in implementing disaster management initiatives and contradictions in existing policies. This study points out the redundancy of elected municipal bodies for taking flood resilience measures, due to increasing proliferation of nondemocratic administrative bodies and underlines the need to bridge the gap through agendas cutting across sectors and institutions.

“…The alternative means to reduce the risk of flooding is to reduce the damage caused by flooding. Flood proofing and floodplain management (Davar et al, 2001), dike compartments (Vis et al, 2001), room for the river (Silva et al, 2001) and River and Land (Netherlands Ministry of Transport, Public Works, and Water Management, 2001) are examples of proposed flood management policies that focus on reducing the damage inflicted by floods while still allowing flooding to occur.…”

“…The strength of culture in decision making can be overwhelming. For example, in Bangladesh, although the government is aware of the advantages of living with the floods, it still favors the use of flood control structures (Davar et al, 2001). A quick overview of the relationship between political powers and large water projects in the United States suggests that in most instances the party in power was more hierarchal (e.g., the Hoover Dam) than egalitarian.…”

The aim of this paper is to compare two views of flood management and thus add to the present thinking of living with floods as opposed to the traditional approach of flood control. The traditional pathway has widely been adopted in developed countries and aims to control floodwaters by means of dams and dikes. The alternative pathway tends towards a policy whereby society lives with the floods by being prepared and having the right damage reduction measures in place. In this paper two pathways are tentatively compared for the Lower Incomati Basin, Mozambique. In the design cultural theory is considered, as is how the design of each path may look according to different management perspectives. The Lower Incomati Basin provides an interesting case study as it is in a relatively undeveloped state. Hence, it is an ideal area for conducting research into the application of alternative flood management strategies. The preliminary results suggest that both pathways are feasible. However, considering recent hydrological extremes such as the 2000 floods, the resilient pathway may ultimately be a more appealing flood management strategy.(KEY TERMS water management; social and political; flood risk; cultural theory; flood management scenarios; Incomati River; Mozambique.)
