Hydrodynamic Pressure due to Earthquake
The horizontal acceleration increases the water pressure as the dam accelerates towards the reservoir and water resists the movement due to its inertia.
The pressure distribution is parabolic in nature.
The magnitude and its location from the base of the dam is given in the figure below:
Where,
Kh = Horizontal seismic coefficient, γw = Unit weight of water (kN/m2), H = Height of the dam (m), and Pe = Hydrodynamic pressure (kN/m2).
As per Von Karman it is parabolic
As per the Zanger method, it is Elliptical cum parabolic
