Research ArticleOpen accessEvery word in the titleTransverse Bed-Slope, Lateral Bed-Load Rate and Bed-Load Deviation Angle in Meandering Alluvial StreamsYoussef Ismail HafezA novel expression for the deviation angle of the bed-load discharge is developed which allows its distinction with the other deviation angles of the flow velocity and boundary shear stress. A transverse bed-slope equation is developed which compares very well with experimental data and field data at the Fall River and Muddy Creek, USA. Stream-wise computations are successfully performed of … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 9 Sep 2024 · 4,912 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Aspect Ratios and Number of Meandering Turns on Performance Limit of an Inclined Closed-Loop Oscillating Heat PipeN. Panyoyai, P. Terdtoon, P. SakulchangsatjataiProblem statement: The purpose of this research was to determine the effects of aspect ratios and number of meandering turns on performance limit of an inclined closed-loop oscillating heat pipe. Approach: The Closed-Loop Oscillating Heat Pipe (CLOHP) was made of a long copper capillary tube. The geometrical sizes, which were the variable parameters of this study, were as follows; the … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,081 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPredictive Dynamics of Channel Pattern Changing Trends at Arial Khan River (1977-2018), BangladeshRathindra Nath Biswas, Md. Juel Mia, M. Nazrul IslamArial Khan River is right bank distributary of Ganges-Padma River systems flowing southwest region of Bangladesh. It is morphologically very dynamic meandering river: where the delta-building process is more active than other distributaries of Ganges-Brahmaputra-Meghna (GBM) River basin. This study analyzes, morphological variables- channel length, valley length, channel area and channel patterns of Arial Khan River. A major portion of … …Current Research in Geoscience, Vol. 8, Issue 1 · 16 Nov 2018 · 9,800 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Distance of the Submerged Vanes from the Outer Bank on Sediment Movement within 180° BendJaafar S. Maatooq, Barq A. AdhabA small aspect ratio of submerged vanes when used near the outer bank at the angle of attack between 10° to 20° and at the initial height above the bed between 20-40% of flow depth is considered one of the most successful river training structures. Vanes when located within the bends of river, produces helical swirls at inverse action with … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 3 Jul 2017 · 7,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel River Meander Migration and Cutoff Model: A New PerspectiveYoussef Ismail HafezAccurate prediction of river meander migration is crucial for effective river management and operation, particularly in light of climate changes and human-induced interventions. Existing models often rely on single-equation approaches, such as bank erosion rate versus excess bank velocity or excess bank shear stress, which limit their ability to comprehensively capture the complex dynamics of meander evolution. This study presents … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 21 Mar 2025 · 7,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeobody Architecture and Petroleum Potential of the Yowi Field, Offshore Eastern Niger Delta, NigeriaPrince Suka Momta, Minapuye Isaac OdigiA study on geobody architecture and petroleum potential of the Yowi Field has been carried out by integrating well logs and 3D seismic data. The objectives of this study include: The determination of the lateral continuity of key horizons; identification of gross geobody distribution and architecture; and the petroleum potential of the field. Well log correlation shows that key horizons … …Current Research in Geoscience, Vol. 6, Issue 1 · 16 Dec 2015 · 7,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractRiver Flow Conditions and Dynamic State Analysis of Pahang RiverMuhamad Barzani Gasim, M. E. Toriman, Mushrifah Idris et al.Pahang River (Sg. Pahang) is the longest river in Peninsular Malaysia. Flood is a common event in Pahang River Basin during wet season which triggered by monsoon season. The hydrodynamic study of Pahang River should be well understood especially when it is a target of northeast monsoon which influenced the Pahang River Basin every year (from November to March). 17 … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 10 Jan 2013 · 8,704 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Inclination Angle on Performance Limit of a Closed-End Oscillating Heat PipeT. Hudakorn, P. Terdtoon, P. SakulchangsatjataiThis study presents the effect of inclination angle on the performance limit of a Closed-End Oscillating Heat Pipe (CEOHP). The study was divided into 2 corresponding parts. The first part was visual study. The CEOHP was made of Pyrex glass tube with the inner diameter of 1.0 mm, evaporator length of 50 mm and had 10 meandering turns. The lengths … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,516 accessesView PDFCite
