Abstract: The second-order nonlinear differential equations of motion in the case of a rocket in drag-free powered-flight under constant transverse (normal to the focal radius) thrust are solved by series ...

Abstract: Hydrodynamic pressures on the vertical upstream face of straight dams during horizontal earthquakes were studied by Westergaad in 1933, and an analytical solution was obtained. Assuming that water is incompressible, an ...

Abstract: Assuming that concrete is a homogeneous porous material in gravity dams, pore pressure intensities at drain wells near the upstream face of dams were studied. In general, the piezometric head of the seepage flow through a ...

Abstract: An innovative cascading spillway was selected to replace a reinforced concrete slab/discharge pipe river outfall structure, which required frequent maintenance and subsequently collapsed as a result of scouring and piping ...
