a. 1. Field wave data from a buoy offshore of Town of Stormy where water is d=20 m deep indicates that the significant wave height is H=3.5 m and peak wave period is To=7 sec. Write down the equations, based on the data provided, for horizontal and vertical orbital velocities of fluid's particles (u and w, respectively), and hydrodynamic pressure, pa- b. Plot vertical profile of u, w Pd, and ps in the water column from SWL to the bottom under wave crest. (ps: Hydrostatic pressure) C. Determine the magnitude of maximum horizontal orbital velocity, u, at the bottom. 2. A pressure sensor mounted on ocean bottom records maximum and minimum pressures of 54.5 KN/m and 41.0 kN/m at t= 21:22:35 and t= 21:22:38, respectively. (40%) a. What is water depth at the sensor? b. Calculate wave height, celerity, energy and power at the sensor. Pressure Sensor 3. Figure below shows the Lake Erie imagery as well as the NOAA active water level gages. Following a strong wind blowing from southwest to northeast over the lake, a NOAA water level gage near Buffalo records the maximum storm surge at 3 m at 2:30 pm. The high surge initiates low frequency motions (long wave) known as seiche. The seiche can propagate along the lake's longer axis. Given the distance from Buffalo, NY to Toledo, OH is approximately 400 km and assuming the lake average depth is approximately 20 m, determine the time of arrival of high water level at Toledo .
