More than 40% of water networks in Egypt are over 40 years old. Consequently, Egypt loses around 30% of daily water produced, which accounts for 25.5 Million m3. In this study, Darwin Calibrator was used to predict the proximate location of water leakage in a DMA. This study presents a physically-based method for WDNs calibration of hydraulic models which intends to support leakage, assessment, monitoring and management from the initial stages. Results indicated that the mean pressure (Pa) for inlet at Elshewash measuring point was 20.89 (Pa) and the mean flow was 18.3 (m3). Conversely, mean pressure for outlet was 18.3 (Pa) and mean flow was 8.22 (m3). At Rawafee El Quser measuring points was1.89 (Pa) at the inlet point and mean flow was 17.42 (m3). However, at outlet mean pressure was 1.81(Pa) and mean flow was 6.3 (m3). In all the networks where the node's pressure and input discharge were introduced to the program as observational data, leakage location was determined at or in the exact location. The location and the amount of leakage were calculated. These results were similar to the leakage resulting from the field inspection. It is inferred that the model calibration could lead to a reduction of water leakage by increasing predictive capacity and monitoring instruments, establishing an instant pressure control mechanism and optimising pipe maintenance strategy. These actions could benefit the environment as a result of water and energy savings.","PeriodicalId":11685,"journal":{"name":"Environmental Engineering and Management Journal","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69522699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 focus is on comparing different irrigation techniques in terms of their water savings, cost efficiency, and crop yields, in relation to the conventional flooding method (CFM). Specifically, the research considers the responsive drip irrigation system (RDI), subsurface drip irrigation (SDI), and raised-bed irrigation method (RSB). The data for this study relates to a 1-hectare tomato farm located in the Potohar plateau of Pakistan. Joint interview sessions were conducted to gather integrated data, along with information from previous studies. To analyze the cost-effectiveness of the irrigation techniques, the study utilizes system dynamics (SD) and employs \"VENSIM PLE\" software. A single SD model was created to meet the requirements for cost-effectiveness analysis (CEA), simulating the implicated techniques over a period of 25 years. Additionally, an optimization scenario was developed using geometric mean maximization, aiming to maximize monetary benefits while maintaining environmental benefits in equilibrium. The findings of this study indicate that the cost-effectiveness ratio (CER) for water-saving capacity is highest for RDI, which can save 0.135 million m 3 of water over 25 years. Furthermore, RDI achieves a 78% higher crop yield compared to the CFM. On the other hand, SDI demonstrates the highest CER for crop yield, offering 41.5% more benefits to farmers when compared to the CFM.","PeriodicalId":11685,"journal":{"name":"Environmental Engineering and Management Journal","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69523416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
