The stream then deposits material along the adjoining meander and eventually blocks off its water supply, as shown in Figure 9.14. The basic calculation is really quite simple: Just take the pond’s length and width and multiply each by twice the depth of the pond at its deepest point. A meander, in general, is a bend in a sinuous watercourse or river. In the middle course the river has more energy and a high volume of water. The speed of the flow cuts away the outside bank of a loop in a process called erosion.
