Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
Lagrangian function. Lagrangian function, also called Lagrangian, quantity that characterizes the state of a physical system. In mechanics, the Lagrangian function is just the kinetic energy (energy of motion) minus the potential energy (energy of position).
THE LAGRANGIAN METHOD. If we have a multidimensional setup where the Lagrangian is a function of the variables. x1(t);x2(t);:::, then the above principle of stationary action is still all we need. With more. than one variable, we can now vary the path by varying each coordinate (or combinations. thereof).
