Evolutionary and Holistic Assessment of Green-Grey Infrastructure for CSO Reduction
نویسندگان
چکیده
Recent research suggests future alterations in rainfall patterns due to climate variability, affecting public safety and health in urban areas. Urban growth, one of the main drivers of change in the current century, will also affect these conditions. Traditional drainage approaches using grey infrastructure offer low adaptation to an uncertain future. New methodologies of stormwater management focus on decentralized approaches in a long-term planning framework, including the use of Green Infrastructure (GI). This work presents a novel methodology to select, evaluate, and place different green-grey practices (or measures) for retrofitting urban drainage systems. The methodology uses a hydrodynamic model and multi-objective optimization to design solutions at a watershed level. The method proposed in this study was applied in a highly urbanized watershed to evaluate the effect of these measures on Combined Sewer Overflows (CSO) quantity. This approach produced promising results and may become a useful tool for planning and decision making of drainage systems.

seattle has been working at green infrastructure for over a decade, and its commitment over many years has resulted in a serious overall program. the city does not yet have a comprehensive citywide green infrastructure plan; its Comprehensive drainage plan is generally supportive of green infrastructure (which it dubs “natural drainage strategies”), but does not spell out an overall vision of i...
متن کاملA Thinning Method of Linear And Planar Array Antennas To Reduce SLL of Radiation Pattern By GWO And ICA Algorithms
In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...
متن کاملA Holistic View of Health Infrastructure Resilience Before and After COVID-19
Large-scale events such as COVID-19 show that there are situations that can lead to huge stress on health infrastructuresystems (HIS). The pandemic reveals that it is very difficult to protect HIS from all kinds of possible hazards. Considerthe trend of these types of viruses, such as N1H1, SARS and Ebola. These types of hazards could be more frequentand extreme in the future....
متن کاملA New Approach for Solving Grey Assignment Problems
Linear assignment problem is one of the most important practical models in the literature of linear programming problems. Input data in the cost matrix of the linear assignment problem are not always crisp and sometimes in the practical situations is formulated by the grey systems theory approach. In this way, some researchers have used a whitening technique to solve the grey assignment p...
متن کاملImpact evaluation of green-grey infrastructure interaction on built-space integrity: an emerging perspective to urban ecosystem service.
This paper evaluates the role of urban green infrastructure (GI) in maintaining integrity of built-space. The latter is considered as a lateral ecosystem function, worth including in future assessments of integrated ecosystem services. The basic tenet is that integrated green-grey infrastructures (GGIs) would have three influences on built-spaces: (i) reduced wind withering from flow deviation;...
