Research ArticleOpen accessPhrase in the titleOptimization of Hydraulic Parameters of Iranshahr Alluvial AquiferJafar Rahnama-Rad, Mohammad Yaghoub Bavali, Reza DerakhshaniProblem statement: The Iranshahr aquifer consists of an unconfined layer. We simulated groundwater flow of the Iranshahr aquifer in a conceptual model. This model is a suitable tool for management of groundwater system and would also be effective when applied in other countries. Approach: In this study, we constructed the conceptual model of Iranshahr aquifer, which is important and applicable … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,547 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTime Dimension Parameters of the Dual-Porosity Reservoir Determination using Periodic Hydraulic Pulse TestingMarat Ovchinnikov, Kushtanova Galiya GatinishnaThe process of periodic hydraulic pulses propagation in porous fractured media of dual-porosity near a vertical well is considered. Using the calculation data as the base, it is shown that the effect of the time dimension constant on the form of the filtration wave curves is essential. The conclusions on possibility of hydrodynamic model types verification which adequately describe the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 9 Sep 2016 · 6,999 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDifferent Sorption Approaches and Leachate Fluxes Affecting on Mn2+ Transport through Lateritic AquiferSrilert Chotpantarat, Chakkaphan SutthiratProblem statement: Contamination of the underlying aquifer beneath a mining area is usually of great concern even when a prevention plan has been implemented. Approach: To assess the potential risk of heavy metal contamination, the simulation of heavy metal transport was carried out with different leachate fluxes and sorption parameters derived from equilibrium models with linear and Langmuir isotherms and … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimate of Safe Angle for Cut Slopes Under Different Geology and Rainfall Intensity in Central NepalPrabin Shrestha, Khomendra Bhandari, Mahendra Acharya et al.This research has been carried out on a cut slope of Kathmandu-Terai Fast Track Road near Koppugaon located at Dakshinkali Municipality, Kathmandu. The cutting of the slope without considering the possible effects of geological parameters of slope material may cause unexpected slope failures which may cause loss of lives and properties. This research deals with the effects of rainfall and … …Current Research in Geoscience, Vol. 13, Issue 1 · 26 Nov 2024 · 9,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Climatological Components on Runoff Modeling using SWATHamid-Reza Rabiefar, Sayed-Reza Alvankar, Kaveh Ostad-Ali-AskariIt was planned most hydraulic projects, for instance barriers, it was defined the overflow of the rivers. If the river absences any position to measure the yield, the hydraulic models can be utilized to estimate it. SWAT is widely-used computerized mockups. It was required to feed such influential climatological information as precipitation, temperature, wind speed, solar radiation and relative humidity, … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 30 Dec 2020 · 6,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Rumen Content by Indigenous Microorganisms in a Modified Anaerobic DigesterAlhassan Salihu Adam, Sani Yahaya, Haruna Musa et al.The current work was designed to assess the effect of modification of model digester on the kinetics that affects efficiency in biogas generation using bovine rumen content as the feedstock. A biogas plant consisting of conventional and modified fixed-dome digesters (each with 2 m3 capacity) was established; and bovine rumen content was used as feedstock. Standard methods were used to … …Energy Research Journal, Vol. 11, Issue 1 · 26 Sep 2020 · 6,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydraulic Flow through Engineering Bentonite-Based Containment BarriersEric Wooi Kee Loh, Devapriya Chitral WijeyesekeraThis paper presents the use of software modelling as a tool to study the impact of hydraulic "resistivity" on the contaminant transport through bentonite-based containment barriers. A sensitivity analysis on the predicted data was carried out by varying the boundary conditions as well as the hydraulic resistance to flow through varying contaminant transport parameters. Accordingly, both advective and diffusive flow … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 4 Nov 2015 · 6,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractOperational Fault Diagnosis in Industrial Hydraulic Systems Through Modeling The Internal Leakage of its ComponentsP. Athanasatos, D. Koulocheris, T. Costopoulos, K. RaptisIn this study, a model of a high pressure hydraulic system was developed using the bond graph method to investigate the effect of the internal leakage of its main components (pump, cylinder and 4/2 way valve) on the operational characteristics of the system under various loads. All the main aspects of the hydraulic circuit (like the internal leakages, the compressibility … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 7,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Measurement of Drilling Parameters to Evaluate the Mechanical Properties of SoilsDaniele Pettinau, Pierpaolo Oreste, Marilena Cardu, Davide GuidarelliAny underground work, carried out either to perform excavations, should be based on detailed knowledge of the geological, hydrogeological and geomechanical conditions of the underlying materials. The continuous automatic diagraphy is a test that consists in the continuous surveying of drilling parameters, with total destruction of the core, which can be used, together with geognostic probing surveys and a detailed … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariability of Hydraulic Conductivity Due to Multiple FactorsSanjit K. Deb, Manoj K. ShuklaSoil properties are greatly influenced by intrinsic factors of soil formation as well as extrinsic factors associated with land use and management and vary both in time and space. Intrinsic variability is caused by the pedogenesis and usually takes place at large time scales. The variability caused by extrinsic factors could take effect relatively quickly and could not be treated … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 13 Aug 2012 · 10,228 accessesView PDFCite
