“…The photomicrograph of DS indicates the rounded and semi-angular particle shapes with smooth surfaces (Figure 1c) which are typical particulate characteristics of quartz sand weathered and transported via aeolian processes in deserts [31]. Carbonate sands are present throughout the Wahiba sand area with some quartz-rich sands in the Southern region [32]. The elemental analysis (Table 1) confirmed the presence of elements, calcium, carbon, and oxygen in the sand sampled from the northern ridge.…”

Use of Reservoir Sediments to Improve Engineering Properties of Dune Sand in Oman

Managing sediments dredged from reservoirs of recharge dams is an environmental issue, however, these sediments can be an abundant and economical source of fine-grained fill soil. This experimental investigation quantifies the geotechnical properties of a reservoir sediment used to improve engineering properties of a poorly graded dune sand in Oman. The binary mixes were prepared with different percentages (5, 10, 20, 50, 75, 90, 95%) of sediment with sand. Laboratory tests such as gradation, consistency limits, compaction, and unconfined compression tests were performed to measure the engineering characteristics of the binary mixtures. The results showed that the maximum dry density increases up to a sediment content of 50% and then decreases with further increase in the sediment content. The optimum water content increases with the increase in sediment content from 17% for pure sand to 22.5% for pure sediment. The optimum moisture content shows a good correlation with the plastic limit of the binary mixture of sand and sediment. The unconfined compressive strength substantially increases with sediment content up to 75% and then decreases with further increase in the sediment content. The binary mixture of sand sediment is sensitive to moisture, however, the order of strength stability against moisture is dune sand mixed with 75, 50, and 20% sediments. The addition of sediment to dune sand improved the uniformity coefficient to some extent with an increase in the maximum and minimum void ratios as well. The elemental analysis of the sediment confirms that the material is non-contaminated and can be employed in geotechnical engineering applications as a sustainable and environmentally friendly solution.

“…The subsurface geology of the United Arab Emirates, has been substantially influenced by the deposition of marine sediments associated with numerous sea level changes during relatively recent geological time. With the exception of mountainous regions shared with Oman in the north-east, the country is relatively low-lying, with near surface geology dominated by Quaternary to late Pleistocene age, mobile aeolian dune sands, and sabkha/evaporites deposits [7]. These superficial deposits were underlain by alternating beds of siliceous calcarenite, calcareous sandstone, siltstone, and conglomerates [3,8].…”

For assessing the geotechnical capacity of reinforced concrete bored piles, instrumented static compression load tests are often utilized in high-rise building projects. To better understand the geotechnical characteristics, this article discusses the axial behavior of preliminary compression test piles installed at the Burj Khalifa Foundation in Dubai. These tests were carried out for 1500mm and 900mm diameter piles prior to foundation construction, up to an ultimate test load of 60260kN. Vibrating wire concrete embedment strain gauges, comprising four units at six levels, were installed on the preliminary test piles. Results indicate that the skin friction was increased after the pile test as compared to the values used for the preliminary pile design. Subsequently, four working load tests were also performed during the construction of the foundation to confirm the final pile design. This article explores the results of static pile load test interpretation, an important factor in enabling reasonable construction settlement prediction, including the pile interaction effects.

“…The topography of Kuwait is generally of low relief, gentle and smooth surfaces. The mainland slopes generally towards the sea at an average gradient of 1 in 500, the highest elevation being 270 m in the south‐west corner (Poulos, 2018: 3). The major topographical features in Kuwait are Jal Az‐Zor escarpment, Wadi Al‐Batin and Ahmadi Ridge (Al‐Sarawi, 1995: 493).…”

Located north of the Arabian Gulf, the small island of Failaka is historically an important landmark of Kuwait. The importance of the island is likely a result of its strategic position on the trade route between the early civilizations of Mesopotamia and Dilmun. Dozens of sites, dating from the Early Bronze Age to the Late Islamic Period have been discovered on Failaka Island so far (Makharadze et al., 2017: 178). As a result of the Kuwait-Georgian Archaeological Mission in 2011-2019, new archaeological sites of different periods were identified on the island of Failaka. One of the problems of the island of Failaka is the lack of fresh groundwater. The existence of a water table cannot be explained by the impluvium (watershed) due to the small size of the island (Dalongeville, 1990: 34). In 2013-2016, during the Kuwait-Georgian archaeological missions, Late Islamic seasonal settlement structures were found in the north-eastern part of the island (Chkhvimiani, 2019: 181-187). It was established that some of the sites were related to water-gathering systems (group of KG12 sites). In this area, periodic and seasonal rainwater was flowing down the elevated slopes towards the natural depression along N-NW-directed artificial channels. After reaching the lowland, the rainwater was trapped and/or
