HMS solves the depth-averaged 2D shallow water equations with robust numerical methods. Most importantly, depth-dependent roughness and depth-dependent infiltration methods are implemented and allow the model to simulate a bunch of scenarios. Calibration and validation results are evaluated based on the criteria of the Nash-Sutcliffe Efficiency (NSE) and Standard Deviation Ratio (SDR). Both, the calibration and validation cases achieve very good agreements between computations and measurements with NSE all higher or equal than 0.97 and SDR all smaller or equal 0.17. The results demonstrate the superiority of the depth-dependent infiltration method when compared to a constant infiltration and the necessity of the depth-dependent roughness approach for accuracy and stability reasons. The methods implemented here might also improve other shallow water models.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"652 - 664"},"PeriodicalIF":2.7,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46315182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel methodology to support pipe rehabilitation planning, including the establishment and scheduling of interventions in the medium and long-term using the graph theory, is developed, and demonstrated using a real case study. This methodology is divided into two main phases: the first is the definition of rehabilitation pipe groups according to the available budget and pipes connectivity and the second is the scheduling of these groups over time according to relevant criteria. This approach allows a clearer correspondence between the financial amounts to be annually invested in rehabilitation and a grouping of single pipes to be rehabilitated. Results demonstrate that the methodology allows a better and advanced planning of interventions when compared with the current traditional approaches applied by water utilities.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"769 - 781"},"PeriodicalIF":2.7,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49157010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-dominated Sorting Genetic Algorithm II (NSGA-II) is one of the most used algorithms in the water industry, requiring a preliminary parameter tuning process. The lack of guidelines on how to tune model parameters generally limits the use of these algorithms by researchers or practitioners and, as such, fails to be used in real-life problems. The current paper explores different NSGA-II parameterizations for the optimal location of pressure sensors by using a multi-objective optimization methodology applied to a real distribution network. Results show that (i) both the uniform and simulated binary crossover operators (depending on the internal parameters) produce the best results, being the former recommended since it does not require further parameter tuning; (ii) polynomial mutation with lower probability value should be chosen; and (iii) the distribution indices of polynomial mutation have a minor effect on NSGA-II performance.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"738 - 750"},"PeriodicalIF":2.7,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44968365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nature-based solutions, such as constructed wetlands, are an option for the treatment of greywater, provided they are used by and useful to the community. We explored the effectiveness of iterative design for two pilot constructed wetlands in an informal settlement in Johannesburg, South Africa. Using ergonomics and human factors (E/HF) design approaches, this study evaluated the usability and postural risks associated with interactions with the constructed wetlands to motivate (and evaluate) design changes to increase use and reduce the risk of musculoskeletal pain. An elevated work area reduced musculoskeletal risks and a larger work area allowed more users at one time. The raised work areas provided other benefits such as stormwater and sewerage protection. The value of E/HF as part of a broader transdisciplinary team was demonstrated by embedding the design in the activities of the community.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"624 - 637"},"PeriodicalIF":2.7,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42435810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The validated Storm Water Management Model (SWMM5.1) was employed to assess the effectiveness of LID-BMPs in mitigating runoff volume. The hydrological model was calibrated and validated with nine in-site measured flood hydrographs. 11 LID-BMP scenarios were planned to determine the most effective combination of LID-BMPs. The results showed that according to the site conditions, Infiltration Trench (IT) and Rain Barrel (RB) practices with 22.2% and 0.4% reduction rates had the highest and lowest efficiency in reducing urban runoff. By assessing various combinations of LID-BMPs, it was found that the combination of IT, Bio-Retention (BR), Stormwater Dry Ponds (SDP), Porous Pavement (PP), and Rain Garden (RG) provides the most effective strategy for runoff management.

While detailed studies exist for the world’s temperate zones, they are few for tropical zones where most of future urbanization may occur and where flooding is already a problem. A tropical watershed in Costa Rica was used to analyze the urban development and the associated hydrological response between 1945 and 2019, based on remotely sensed data and a numerical model. Using a detailed spatial-temporal approach, we found that the watershed’s overall urbanization over the timespan (+64%-points urban-areas) had led to major hydrological challenges (+80% runoff-volume, +220% peak-flow-rate and maximum-specific-discharge, and −25 min time-to-peak). These challenges were then placed in the context of historically reported flood events, providing a basis for spatially-differentiated flood mitigation actions and for guiding future urbanization.
