Shoreline development index

The shoreline development index of a lake is the ratio of the length of the lake's shoreline to the circumference of a circle with the same area as the lake. It is given in equation form as , where is shoreline development, is the length of the lake's shoreline, and is the lake's area. The index can also include the length of island shoreline, modifying the formula to , where is the combined length of the lake's islands' shoreline. Shoreline development correlates strongly with lake area.
