About Watershed Analysis

Identify and analyze all watersheds intersecting a selected component road or identify watersheds from a single low point in the terrain.

• A single analysis may identify multiple watersheds. Each watershed is a selectable feature. Click inside a watershed to display its properties on the stack.
• Drainage Design displays watershed extents and stream locations, and marks where streams cross roads with a blue balloon pin.
• Analysis uses the existing ground surface prior to placement and grading of a component road. Analysis aims to identify existing drainage patterns prior to road placement and design.
