“…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].…”

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.

“…Further details on the model, including how the other SuDS infrastructure are simulated and parameters used, can be found in Chapman and Hall (2021) and Supplementary Table 1, respectively. As part of this modeling process, catchments for the study region were automatically delineated by the program, based upon a LIDAR composite digital terrain model (DTM) at 5 m resolution, sourced from the Ordnance Survey (Ordnance Survey, 2021).…”

With global urban populations expected to reach 5 billion by 2030, large-scale urban development is required to support and sustain this growing populous. At the same time, city planners are facing the pressures of climatic changes, which forecast more intense rainfall events, further exacerbating the existing challenge of surface water flooding in urban locations. Sustainable drainage systems (SuDS) are one proposed solution to help alleviate such problems, yet much still remains to be known about their operation, performance and potential benefit provision beyond the neighborhood scale, or within a mixed-form development. Using a case study of the Cambridge to Oxford Arc (a region of England earmarked for extensive urbanization), development patterns of different extents and spatial layout were modeled. The Stormwater Management Model (SWMM) was then used to simulate surface water runoff conditions in these developments during a 1-in-10-year rainfall event. Whilst denser scenarios typically led to greater peak runoff rates and total runoff volumes, this was not always the case under some SuDS designs as the denser scenarios provided the opportunity for more SuDS provision. The proportion of different surface cover types had a strong influence of runoff volumes and rates (due to the different impermeable surface areas and SuDS provision), and since the different housing typologies offered different proportions under each development scenario, there was no single typology that showed the lowest or highest runoff volume across all scenarios. The findings of this study highlight the importance in a planning context of considering multiple typologies and their footprints of different surfaces to maximize the potential of the development design in achieving the development's goals.

Blue–green infrastructures (BGI) play an important role in addressing contemporary challenges posed by urbanization, climate change, and demographic shifts. This study focuses on the parameterization of BGI within hydrological models, specifically emphasizing the Low Impact Development (LID) module of the Storm Water Management Model (SWMM), supplemented by the SWMM-UrbanEVA evapotranspiration model. Employing a systematic approach, a transferable framework is developed to categorize BGI types, leading to a comprehensive parameterization toolset. This toolset includes parameter estimates for predefined BGI types, encompassing both natural and technical systems with a specific emphasis on plant-specific parameterization. The justification of these parameter estimates is supported by an extensive literature review. Sensitivity analyses reveal the influence of plant-specific parameters, such as the crop factor (KC), and soil storage capacity, on water balance and peak runoff. Additionally, this study presents practical guidelines to enhance the comprehension of model behavior and ensure the highest possible quality in model parameterization. While further research on validity and transferability of the toolset is required, the findings of this study provide useful support for the differentiated representation and analysis of hydrological processes in urban environments. As a result, this study serves as a valuable resource for researchers, practitioners, and decision makers, facilitating the implementation of sustainable water management practices in urban settings.
