This article goes a step further with the main objective of this study to explore water-practitioners’ viewpoints regarding the water supply-side and water demand-side management measures in coping with future climatic impacts to achieve urban water security. Interviews were conducted with water-professionals from regional urban water authorities of Queensland, Australia. From a water-practitioner’s viewpoint, surface water is perceived to remain a high-priority water resource for the region, although climate-change is projected to make this resource more vulnerable in the area. Climate-change risks have rarely been considered as a selection-criterion when long-term water solutions were investigated by water-practitioners. Although non-pricing water demand management policies were used to reduce water demand in the region, pricing-based water demand management tools are perceived by the water-professionals to be the most effective at reducing water demand in the study area, if implemented.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"723 - 737"},"PeriodicalIF":2.7,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43804516","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}

In this paper, we present a data-driven leak localization approach leveraging a connected Geographical Information System together with an autoencoder to perform anomaly detection on time-variable sensor data. Data-driven approaches are able to circumvent many of the uncertainty issues associated with model-based approaches, but they usually require significant amounts of high-quality data, reflecting many different leak scenarios, to perform well. Our approach obviates this requirement by relying only on leakless data during model training. We examine the efficacy of this approach on 19 realistic leak experiments conducted in the field. Based on these evaluations, we were able to achieve average search costs as low as 2.2 kilometers, for a total network length of 215 kilometers.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"859 - 881"},"PeriodicalIF":2.7,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41460397","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}

To address these challenges, this study aims to prepare and implement the optimal instructions for pipe replacement with maximum hydraulic performance, minimum cost, and minimum uncertainty. Herein, a robust clustering multi-objective (RCMO) approach is developed by combining five models, including hydraulic simulation, multi-objective optimization, pipe failure rate prediction, non-linear interval programming, and multi-criteria decision-making. In this procedure, a clustering method is implemented to reduce the uncertain scenarios of the multi-objective optimization. The new approach is applied to a WDN in Gorgan, Iran. Implementing the optimal instruction increases the network’s physical and hydraulic performance by 56% and 35%, respectively, and decreases the annual deficit of nodes’ demand between 69% and 93%. Also, the proposed methodology reduces the optimization run time by about 99%.","PeriodicalId":49392,"journal":{"name":"Urban Water Journal","volume":"20 1","pages":"689 - 706"},"PeriodicalIF":2.7,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49219122","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}

This current scoping review addressed this issue in the case of Mega Manila, Philippines. Quantitative and qualitative analyses of literature were done to support syntheses and identify gaps in water quality monitoring and management. The microbial quality of freshwater bodies and drinking water within the region is indicated by the detected microbial communities, bacterial species, and genetic elements associated with drug resistance, through culture-dependent and -independent approaches. Heavy metals were found to contaminate freshwater bodies but were absent in the drinking water supply. Overall, our findings highlight the need for harmonizing monitoring tools and data to assess water safety. Outside Mega Manila, freshwater bodies and drinking water supply must be monitored.

The optimization significantly increases all models' accuracy except Papadakis, indicating its remarkable robustness in coastal cities. Comparison between all models demonstrates that the Linacre-1994 optimal model has the best accuracy.
