Has a water barrier on top C. Has a water barrier at the bottom D. Has a free surface. Correct answer: D. Submarines have a free surface; they are subject to atmospheric pressure and are affected by climate conditions, which results in significant seasonal variations: it rains more in spring and summer, causing the water level to rise ； In winter, there is little rain and the water level drops. Hydrology changes regularly with the seasons, and water quality is susceptible to the impact of surface construction projects. Confined water refers to groundwater that fills the space between two aquitards, and it is under a pressure greater than atmospheric pressure. Confined water does not have a free surface and is subjected to a certain static pressure; the level of confined water represents a virtual hydrological parameter known as head.
