Tidal Conversion by Subcritical Topography
Analytical estimates of the rate at which energy is extracted from the barotropic tide at topography and converted into internal gravity waves are given. The ocean is idealized as an inviscid, vertically unbounded fluid on the f plane. The gravity waves are treated by linear theory and freely escape to z 5 `. Several topographies are investigated: a sinusoidal ripple, a set of Gaussian bumps, a...
متن کاملTidal Conversion by Supercritical Topography
Calculations are presented of the rate of energy conversion of the barotropic tide into internal gravity waves above topography on the ocean floor. The ocean is treated as infinitely deep, and the topography consists of periodic obstructions; a Green function method is used to construct the scattered wavefield. The calculations extend the previous results of Balmforth et al. for subcritical top...
متن کاملVirtual seafloor reduces internal wave generation by tidal flow.
Our numerical simulations of tidal flow of a stratified fluid over periodic knife-edge ridges and random topography reveal that the time-averaged tidal energy converted into internal gravity wave radiation arises only from the section of a ridge above a virtual seafloor. The average radiated power is approximated by the power predicted by linear theory if the height of the ridge is measured rel...
متن کاملenvironmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Processing MBES Data to Detect Changes to Seafloor Topography
Performing precision monitoring for changes to seafloor topography is necessary to accurately examine the state of accidents of all sorts on the coast. Thus, this study proposed a new change detection technique to monitor changes to seafloor topography by systemizing the post-processing technique for MBES sounding data and 3D modeling technique. This study also applied the proposed technique to...
