👉 Maund's law, also known as Maund's equation or Maund's law of stratification, is a theoretical model used to describe how water behaves in stratified layers. It describes the distribution and flow of water within the Earth's surface according to the principle that water moves from areas with lower pressure (e.g., deeper waters) to areas with higher pressure (e.g., shallower waters). The term "maund" is often used in this context to refer to this model.
