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 Articles will not be published until the final proofs are validated by their authors.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.

  • Understanding the impact of geodetic measurements uncertainty on drought assessment: a case study of Europe   Order a copy of this article
    by Artur Lenczuk, Christopher Ndehedehe, Anna Klos, Janusz Bogusz 
    Abstract: A changing climate reveals that drought are becoming more severe and frequent, with cascading impacts on the environment, and people. As opposed to meteorological-based drought indices, GRACE and GPS observations have provided new capabilities and insights that improve understanding of drought dynamics. However, there are also limitations in the use of geodetic data. Thus, we examine the impact of GRACE and GPS residual errors on defined droughts estimating DSI and its uncertainty based on various approaches. Our results indicate the largest uncertainties above 35 degree. We observe a good spatial consistency in displacement uncertainties between GPS and both GRACE-type data for Western Europe, with relative RMS values over 20%. In comparison to original DSI, uncertainties contain 20% and 100% of DSI signal at 48% and 5% of stations for MSC JPL and GPS, respectively. For TCH method, we identify region-dependent hot spots and north-south strips for displacements and DSI, respectively.
    Keywords: global positioning system; GPS; GRACE; vertical displacements; DSI uncertainty; three-corner hat method; drought.

  • Water resource collection, treatment and recycling devices for green building construction   Order a copy of this article
    by Xue Han 
    Abstract: This article also constructed an optimised device data transmission method and a water resource collection and reuse cycle system, including precipitation collection and reuse and domestic and office wastewater collection and utilisation. The optimised device was tested, and the economic benefits, treatment effects, water quality categories, and recycling effects before and after optimisation were compared. The annual economic benefits from optimisation were 8.95 million yuan higher than before. The optimised chemical oxygen demand (COD), turbidity, and conductivity values were all lower than those before optimisation, indicating that the optimised device has a good treatment effect. The optimised water quality categories were divided into class II, class III, class IV, class V and below class V. The proportion of class II that meets the requirements increased by 30.8% compared to before optimisation.
    Keywords: green building construction; water use devices; water harvesting and reuse recycling system; three method water purification integrated plant; green building construction site water.

  • Assessment of bathymetric dataset discrepancies at Al Mismari Reef using historical nautical charts and multibeam bathymetry   Order a copy of this article
    by V.R. Shamji, Faisal Alsaaq 
    Abstract: This study quantifies bathymetric discrepancies at Al Mismari Reef (21.3247 N, 39.0319 E), northwest of Jeddah, Saudi Arabia, by comparing the 500 m depth contour from the 1988 British Admiralty Chart BA 2658 against a 0.5 m resolution multibeam echo sounder (MBES) DTM acquired in 2024 using a Kongsberg EM710 processed in CARIS HIPS and SIPS. The 500 m contour was the only chart feature within the survey footprint suitable for comparison. Across 4,167 points over 5.39 km, the mean depth difference was 72.262 m (RMSE = 76.368 m; SD = 24.708 m; maximum = 139.502 m), with 90% exceeding 50 m. These discrepancies reflect horizontal positioning limitations (?200500 m) of the pre-GPS era amplified by the steep fore-reef slope. The observed differences represent dataset discrepancies rather than confirmed seabed change, confirming the inadequacy of BA 2658 for modern navigational applications.
    Keywords: multibeam echo sounder; bathymetry; dataset discrepancy; Red Sea; BA 2658 nautical chart; IHO S-44; uncertainty analysis; Al Mismari; digital terrain model; DTM.
