LakeShed: a web-based tool for watershed delineation considering lakes and reservoirs

Introduce

This is an web-based tool for watershed delineation considering lakes and reservoirs. The delineation results provide five types of spatial units: lakes, rivers, river sub-basins, lake hillslopes, and unchanneled flow paths.

Key functionalities include:

• Supports watershed delineation for any region of interest worldwide.
• Allows users to customize extraction parameters, including the minimum upstream contributing area for river extraction and the minimum lake area to exclude small lakes.
• Supports user-uploaded DEM data for watershed delineation.
• Watershed delineation is processed by a remote server.
