The elevated concentrations of heavy metals in soil considerably threaten ecological and human health. To this end, the present study assesses metals pollution and its threat to ecology from the mid-channel bar’s (char) agricultural soil in the Damodar River basin, India. For this, the contamination factor (CF), enrichment factor (EF), geoaccumulation index (Igeo), pollution index, and ecological risk index (RI) were measured on 60 soil samples at 30 stations (2 from each station, i.e., surface and sub-surface) in different parts of the mid-channel bar. The CF and EF indicate that both levels of char soil have low contamination and hence portray a higher potential for future enrichment by heavy metals. Moreover, Igeo portrays that soil samples are uncontaminated to moderately contaminated. Further, pollution indices indicate that all the samples (both levels) are unpolluted with a mean of 0.062 for surface soils and 0.048 for sub-surface soils. Both levels of the char have a low potentiality for ecological risk with an average RI of 0.20 for the surface soils and 0.19 for the sub-surface soils. Moreover, Technique for order preference by similarity to ideal solution (TOPSIS) indicates that the sub-surface soils have lower pollution than the surface soils. The geostatistical modeling reveals that the simple kriging technique was estimated as the most appropriate interpolation model. The present investigation exhibits that reduced heavy metal pollution is due to the sandy nature of soils and frequent flooding. However, the limited pollution is revealed due to the intensive agricultural practices on riverine chars. Therefore, this would be helpful to regional planners, agricultural engineers, and stakeholders in a basin area.

“…Based on our comparison of the modern landscape of the study area with the historic topographic maps, the loss of archaeological sites (tells and koms) during the last A key objective in this study was to locate buried water channels and their relationship with archaeological settlements in their vicinity (Jotheri & Allen, 2020). Indeed, the topographical environment of the fluvial palaeolandscapes can provide information about the distribution of the archaeological remains (Carey et al, 2017) and identify settlements significant enough in size and depth of time to leave a signature of a rise in elevation in the landscape (Gupta, 2008;Mahammad & Islam, 2021;Smith, 2021). Unfortunately, the deep traces of the palaeochannels can be difficult to detect because they are covered by thick layers of Nile sediment and more recent human activities (Brown, 2002).…”

Egyptian civilization has long flourished along the banks of the Nile, in the south (e.g. Luxor and Aswan), the Middle (e.g. Giza ‘Great Pyramids’) and North (e.g. San El‐Hagar and Buto), as well as the less populated areas of the Sinai Peninsula, the Western Desert and the Red Sea coast. There are archaeological sites date back to the Palaeolithic period and cover the Pre‐dynastic, Pharaonic, Hellenistic‐Roman, Coptic and Muslim periods. Across the Nile Delta, many of these archaeological sites have disappeared beneath Nile alluvium from the annual inundation or through intensive agricultural use, climate changes and other anthropogenic activities. This study aims to detect the long‐term changes in the landscape of the archaeological area of Burullus on the Mediterranean shoreline in the North Delta of Egypt. By combining data from historic topographic maps with Radar Sentinel‐1 (High‐resolution Level‐1 GRD) and SRTM data, topographic signatures in satellite imagery can be compared with the historic record of archaeological sites, many of which are now lost. Image layering, enhancement and analysis using ENVI 5.1, ArcMap 10.4.1 and Snap 8.0 software as well as Google Earth Pro facilitated the imagery identification and acquisition. The results of this study provide a means of quantifying the significant loss of cultural heritage sites due to anthropogenic and natural changes in the landscape. This analysis has also identified two—previously unknown—potential archaeological sites. Finally, the reconstruction of the paleolandscape of the study area shows the changing relationships of ancient and historic settlements with natural and man‐made waterways over time. Integrating remote sensing data and historic maps offers a method for evaluating paleolandscapes and locating disappeared archaeological sites that can be applied in other areas of Egypt and the world.
