What is Wave Reflection on Structures?
If there is a change in water depth as a wave propagates forward, a portion of the wave’s energy will be reflected. When a wave hits a vertical, impermeable, rigid surface-piercing wall, essentially all of the wave energy will reflect from the wall. On the other hand, when a wave propagates over a small bottom slope, only a very small portion of the energy will be reflected. The degree of wave reflection is defined by the reflection coefficient Cr = Hr/Hi where Hr and Hi are the reflected and incident wave heights, respectively.
How to Calculate Natural Free Oscillation Period for Closed Basins?
Natural Free Oscillation Period for Closed Basins calculator uses Natural Free Oscillating Period of a Basin = (2*Harbour Basin Length)/(Number of nodes along the Axis of a Basin*sqrt([g]*Water Depth)) to calculate the Natural Free Oscillating Period of a Basin, The Natural Free Oscillation Period for Closed Basins, assuming water is inviscid and
incompressible basin oscillations involve standing waves in shallow water. The simplest basin geometry is a narrow rectangular basin with vertical sides and uniform depth. Natural Free Oscillating Period of a Basin is denoted by Tn symbol.
How to calculate Natural Free Oscillation Period for Closed Basins using this online calculator? To use this online calculator for Natural Free Oscillation Period for Closed Basins, enter Harbour Basin Length (LB), Number of nodes along the Axis of a Basin (N) & Water Depth (D) and hit the calculate button. Here is how the Natural Free Oscillation Period for Closed Basins calculation can be explained with given input values -> 5.672777 = (2*40)/(1.3*sqrt([g]*12)).
