Various systems and methods have been developed for the gathering of seawater. One of the most common methods is the use of offshore direct seawater intakes, such as suction chamber. Due to the location of these structures, they can influence marine life by suction of fish. In this research, by considering environmental issues and design parameters...

Line break valves in pipelines are using to prevent environmental hazards caused by the entry of the fluid into the surrounding. The operation of these valves leads to sudden changes in pressure and velocity, resulting in the occurrence of the water hammer phenomenon. The water hammer pressure will cause serious problems such as the destruction of...

Every construction has a certain efficient lifetime after which it would need to be repaired or demolished for further reconstruction. This would cause a specific range of waste materials, called construction and demolition (C&D) wastes. Because of the large volume of these bulky waste materials, their utilization in construction and geotechnical p...

The aim of this study is to model the nature of nonlinear torsional magnetohydrodynamic waves propagating in solar jets as they are elevated to the outer solar atmosphere. The contribution of sequential processes to the transfer of energy is taken under consideration: the nonlinear cascade and shock formation. Thus a straight magnetic cylinder embe...

The aim of this paper was to investigating the effects of soil relative density, construction materials roughness, oil type (gasoil, crude oil, and used motor oil), and oil content on the internal and interface shear behavior of sand with different construction materials by means of a modified large direct shear test apparatus. Tests conducted on t...

Analysis of earth dams is generally conducted in three stages of stability, deformability and water penetration analysis. Lack of sufficient attention to leakage, as one of the most important issues, leads to erosion and destruction of slope stability. The aim of current paper is to analyze the earth dam leakage with respect to the existing uncerta...

Oil and its derivatives such as gasoline, gasoil, and ‎kerosene are the main sources of energy in the transport and ‎industry sectors, and also the most common ‎soil contaminants. Oil contamination of the soils as a serious ‎geoenvironmental problem not only affects soil quality ‎but also changes its geotechnical properties.‎‏ ‏Any changes ‎in the‏...

In the case in which relatively low thickness and high-velocity flow enter into the lower velocity fluid, the resulting interference field of these two flows is called the jet. This phenomenon is the dominant output of power plants and some of the dams. The jets can be divided into two categories of free jets and confined jets, caused by the distan...

The Richard's equation mathematically expressing the infiltration problem is a transport type of equation describing two different phenomena namely advection and diffusion being hyperbolic and parabolic type of differential equation, respectively each having their own physical properties thus a single numerical scheme would not essentially be suita...

In this paper the offset jet entering a domain with a movable bed is simulated by the computer program FLUENT. To achieve this aim, sediment transport is numerically simulated using multiphase systems and the empirical coefficients are studied theoretically. The numerical results are verified by comparing the simulated total load with that obtained...
