This class encapsulates the properties of a watershed area in a surface watershed analysis.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.4.2516.0

Syntax

C#
public sealed class SurfaceAnalysisWatershedData : ISurfaceAnalysis
Visual Basic
Public NotInheritable Class SurfaceAnalysisWatershedData _
	Implements ISurfaceAnalysis
Visual C++
public ref class SurfaceAnalysisWatershedData sealed : ISurfaceAnalysis

Remarks

This class defines a single watershed, specified by an area ID, and watershed type. It also defines the appearance of the watershed area, and contains the IDs of any other areas it drains into.

A Surface watershed analysis typically contains several watershed areas. The Surface.Analysis.GetWatershedData() method returns an iterable collection of SurfaceAnalysisWatershedData objects, one for each watershed area.
