Introduction

To connect water system is based on the grid water system and flow direction. It assigns each river in the water system a unique value.

The water system connection records the node connection information. The red point below is the intersection point between two river segments. A river segment connects two intersection points, or an intersection point and a pour point, or an intersection point and a watershed.

In the result of water system, the river segments should be greater than or equal to 1.
