Research ArticleOpen accessPhrase in the titleEffect of Plowing Depth of Tillage and Forward Speed on the Performance of a Medium Size Chisel Plow Operating in a Sandy SoilS.A. Al-Suhaibani, A.E. GhalyProblem statement: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Chisel plow is widely used by farmers as a primary tillage tool. Performance data for chisel plow operation … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,111 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,409 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleAdvantages of Utilizing Geotextiles in Fixing Sandy Soils and Increasing Shear Strength in Water Conveyance TrenchesAlireza Mardookhpour, Leila OoshaksaraieWith the increasing demand in water supply and either for generation or for irrigation and human consumption, water conveyance structures must guarantee a maximum efficiency at the lowest construction and maintenance costs. Using thin geotextiles allow very low permeability and very high transmissivity. Conclusion/Recommendations: The system constructs a continues, low roughness on the entire section of canal. In this research … …Current Research in Geoscience, Vol. 2, Issue 1 · 23 Jan 2012 · 13,184 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,060 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleOpen ended-coaxial Cable Measurements of Saturated Sandy SoilsAlberto GodioThe application of electromagnetic methods in the radar and micro-wave frequency band allows the fluid content of soils to be estimated; the heuristic or physically-based models permit to relate the observed electrical permittivity of the soils with the porosity and fluid saturation. The role of the effect of the free water and bound water in the overall electromagnetic behaviour of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,800 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDetermination of Draft Force for a 3-bottom Disc Plough Under Sandy Loam Soil ConditionsPaul Okoko, Emmanuel A. AjavThis study was performed to determine the draft force for a 3-bottom disc plough under sandy loam soil conditions. The experiments were conducted using five different tractor speeds (3.6, 5.4, 7.2, 9.0 and 10.8 kilometer per hour(km)) and three tillage depths (10, 20 and 30 centimeter(cm)) with a view to determine the actual implement speed at the different tillage depths. … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 15 May 2020 · 7,384 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAnalysis of Non-Equilibrium Phase Change in Transfers at Low Water Content by Considering the Film FlowMarcel Bawindsom Kébré, François Ouédraogo, Bétaboalé Naon et al.In this study, we analyze the effect of non-equilibrium phase change on transfer at low water content in a sandy soil by considering the contribution of film flow in the motion of liquid water. Indeed, most of the non-equilibrium study methods use for hydraulic conductivity, the van Genuchten-Mualem (VGM) capillary model which does not consider the film flow occurred at … …American Journal of Environmental Sciences, Vol. 17, Issue 1 · 1 Jun 2021 · 6,395 accessesView PDF Cite
