Introduction
The river is divided into the main stream and branches. According to the amount of flow and river shape, the river can be classified.
Based on grid water system, rivers are numbered. The larger the number is, the higher level the river is. SuperMap provides two methods including Strahler and Shreve. For more information, see River Classification Methods.
