“…Then, we calculated the empirical flood frequencies by Equations ( 5)-( 7) and determined the initial statistical parameter values according to Equation ( 8) to fit a theoretical frequency curve. Finally, the typical flood hydrograph in July 1966, which is unfavorable to flood control, was selected, and the peak flow was used as the control standard in accordance with the same ratio amplification method (Equation ( 9)) to derive the 500-year design flood hydrograph and the 10,000-year check flood hydrograph for each flood stage, according to Equation (10), to derive the reservoir capacity of the staged reservoir, to obtain the stage FLWLs.…”

“…The region has worked 62 glacial lake outburst flood (GLOF) since 1935, occurring eight in Nepal [3], once every 3-10 years [4][5][6]. In recent decades, sustainability, resilience, and climate change adaptation flood control strategies have emerged [7], such as low impact development (LID) [8,9], sustainable drainage systems (SUDS) [10,11], green infrastructure (GI) [12][13][14], water sensitive urban design (WSUD) [15,16], etc., which have received positive responses in developed countries. For developing countries faced with population pressure and food shortages, forcing societies to use floodplains, engineering measures, such as dredging rivers, strengthening drainage systems, and building flood walls, continue to be taken to reduce the impact of flooding [17][18][19].…”

A reasonable flood season delineation can effectively implement staged reservoir scheduling and improve water resource efficiency. Therefore, this study is aimed at analyzing the flood period segmentation and optimizing the staged flood limit water levels (FLWLs) for a multi-purpose reservoir, the Longtan Reservoir, China. The rainfall seasonality index (SIP) and the runoff seasonality index (SIR) are used to evaluate the feasibility and rationality of the flood period staging. The fractal method is then used to segment the flood season. Finally, the design flood is carried out to optimize the staged FLWLs. The results show that the SI is an effective indicator for judging the feasibility and verifying the rationality of flood segmentation. The flood period can be segmented into the pre-flood season (12 April–29 May), the main flood season (30 May–3 September), and the post-flood season (4 September–9 November). The FLWLs in the main flood and the post-flood season can be raised by 2.05 m and 3.45 m, and the effective reservoir capacity is increased by 5.810 billion m3 and 6.337 billion m3, according to the results of the flood season division.

“…Sustainable stormwater drainage systems: an alternative to traditional stormwater management systems [84][85][86], which mimics the natural hydrological processes of drainage (infiltration, evapotranspiration, filtration, retention, reuse) lost to urbanisation and the impermeable surfaces associated with the installation of piped drains [87,88]. These systems contribute to the creation of habitats for nature, opportunities for water reuse and improvements in water quality [89].…”

“…These systems contribute to the creation of habitats for nature, opportunities for water reuse and improvements in water quality [89]. While traditional systems use built infrastructure (usually underground) to capture and transport water out of the urban area [86], sustainable stormwater drainage systems use a range of devices-ditches, green roofs, permeable pavements, ponds, constructed wetlands, basins and infiltration ditches-to reduce the flow and overall level of pollution in runoff [86,90].…”

Urban Design Solutions for the Environmental Requalification of Informal Neighbourhoods: The George Dimitrov Neighbourhood, Maputo

2023

View full text Add to dashboard Cite

The current dimension of informal settlements in Maputo requires the definition of action models framed by empirical evidence, taking advantage of pre-existing socio-spatial and environmental conditions to define physical interventions through sustainable urban design strategies, with a view to their physical (and socio-economic) upgrading. Thus, this paper highlights the potential of urban design in the environmentally sustainable upgrading of Maputo’s informal neighbourhoods. This article aimed to develop sustainable and resilient urban design proposals and identify strategies capable of guiding the future process of physical territorial transformation towards a more sustainable model. Methodologically, a literature review was undertaken for the purpose of understanding the issues related to the theme and the general characteristics of informal neighbourhoods, as well as for exploring a case study: the George Dimitrov Neighbourhood. It was concluded that the current fabric of informal settlements possesses physical characteristics which facilitate the application of sustainable and responsive urban design strategies for the requalification of these deprived areas. Despite the marked difference between the spatial configurations of informal neighbourhoods and those of formal cities, it is possible to increase the level of resilience and sustainability of informal settlements through surgical and deep solutions, anchored on the particularities of the existing fabric.

Considering the hydrological cycle, actions focus on individual lots and overall improvements are expected as a cumulative impact across the urbanized area.…”

Changes in the hydrological cycle due to climate change and urbanization augment and accelerate runoff and flooding, degrade the urban environment, and cause human and material losses. Thus, it is important to implement measures that ensure urban hydrological conditions are kept as close as possible to pre-urbanization conditions, preventing floods. In addition to the conventional major and minor systems, cities may establish criteria for percentage of permeable area as well as stormwater management practices such as stormwater detention tanks, a type of low impact development technology (LID). The present study evaluates the adequacy of current practices in private lot detention tank design. It analyses time to empty, total detention time and flood peak abatement provided by detention tanks designed according to Curitiba's (Brazil) Bylaw 176/2007. Based on the results obtained, modifications were suggested to existing legislation to increase the efficiency of the detention tanks and, thus, reduce urban flooding and adapt to climate change. The proposed methodology can be applied elsewhere to guide detention tank design.
