Initially, the shape of the front resembles a Gaussian, with a wide sloping surface and flat top. As the experiment progresses, the front gradually becomes smaller in size and its sides flatten, leaving a sharp peak in the center. While the fluid is not in perfect hydrostatic balance, otherwise the front would last forever, it is stable enough that we can assume hydrostatic balance it is, as we did in our theoretical calculations.
Using equation x, we calculate the radius of deformation to be around 20 centimeters, or half of the width of the tank. Given that the front extends all the way to the outside of the tank
