Basset–Boussinesq–Oseen equation

Have you ever played with water in the bathtub or a pool and noticed that sometimes it's really still and other times it's really wavy and splashing all over the place? Scientists study how water moves and try to create math equations to help them understand and predict what will happen. The basset-boussinesq-oseen equation is a math equation that helps the scientists understand how tiny particles like dust or pollutants move through water that is moving in waves. It's kind of like when you throw a ball into a pool and watch it move around. The equation helps the scientists figure out how the ball will move and where it will end up. The basset-boussinesq-oseen equation is a really complicated math equation, but it helps the scientists understand how things move in water and can help them protect our environment.
