You didn't address this - positive or negative. Additionally, due to the resistive & buoyant forces of the water, a steeper floor under water is not uncomfortable to people. Walking on this slope when it is dry is uncomfortable, however the buoyant forces keeps the body upright & the resistance prevents that "runaway" feeling. This is the same reasoning behind the 12" rise/run standards on swimming pool steps Dave:
