International Journal of Water (IJW)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

Online First articles are published online here, before they appear in a journal issue. Online First articles are fully citeable, complete with a DOI. They can be cited, read, and downloaded. Online First articles are published as Open Access (OA) articles to make the latest research available as early as possible.

Open AccessArticles marked with this Open Access icon are Online First articles. They are freely available and openly accessible to all without any restriction except the ones stated in their respective CC licenses.

  • Monitoring the Processing and Supply of Clean Drinking Water using the Hybrid Gateway Method based on the Internet of Things (IoT)   Order a copy of this article
    by Rindra Yusianto, Rabei Ali, Herwin Suprijono, Marimin Marimin 
    Abstract: This research aims to implement IoT-based monitoring in water treatment systems. A Gateway device will be designed to support the integration of a new IoT-based monitoring system based on conditions at the Petanglong, Indonesia. A Raspberry Pi and Node-Red software were used as programming tools to carry out the Gateway function and create a monitoring dashboard display with the MQTT protocol as a communication path that connects the Gateway device with the cloud server. The results show that the Gateway device can work well in the new IoT-based monitoring system. The accuracy level of data reading between the value in the field and the dashboard display results is 99%, which works ideally at a reading time interval of every 5 seconds, with the difference in data display time and the dashboard display being in the time range of 2

  • A transformative social policy approach to implementing IWRM in Zimbabwe and South Africa   Order a copy of this article
    by Newman Tekwa, Beatrice Dube 
    Abstract: The article examines water policy reforms in Zimbabwe and South Africa, focusing on challenges arising from the adoption of integrated water resource management (IWRM) and neoliberal philosophies. Through the transformative social policy perspective and qualitative research, the paper provides a comparative analysis of both countries’ experiences. Findings highlight divergent approaches, with Zimbabwe's reforms enabling democratic social transformation, while South Africa's emphasis on IWRM principles of economic efficiency and environmental sustainability has marginalized social equity. Considering their shared colonial history, our analysis underscores incorporating historical and contextual factors into water sector reforms for equitable change and protection of vulnerable groups, including women. By examining the intersection of water policy reforms, transformative social policy, and local realities, this study contributes to the discourse on equitable and sustainable water management.
    Keywords: integrated water resource management; irrigation; South Africa; transformative social policy; water reforms; Zimbabwe.

  • Impact of alteration in soil hydraulic variables on collective infiltration using HYDRUS-1D   Order a copy of this article
    by Ali Javadi, Kaveh Ostad-Ali-Askari 
    Abstract: The analysis of sensitivity is a crucial component of modeling. The sensitivity index of the van Genuchten-Mualem parameters on cumulative infiltration under various irrigation managements was calculated in this study using the HYDRUS-1D model. Treatments included two irrigation managements, two irrigation periods (short and long periods) and three irrigation water qualities (ECi= 0.6, 3 and 6 dS/m). The two irrigation managements were intermittent irrigation at the 30% depletion of field capacity (M1) and daily irrigation with 0.15 leaching fraction (M2). The soil columns underwent infiltration tests at 16 and 114 day intervals. Following HYDRUS-1D model calibration of the infiltration process, the impact of a 20% change in soil hydraulic parameters (0.8 to 1.2 parameter values) on cumulative infiltration was examined. Infiltration is most sensitive during the short irrigation period under intermittent irrigation when the soil was dried and wetted successively, whereas it is the most sensitive during the long irrigation period under daily irrigation when the soil was wetted continuously. In fact, as soil permeability increases, infiltration becomes more sensitive to parameter changes.
