Detailed Description

Startup drainage network for mHM.

This module initializes the drainage network at L11 in mHM.

• Delineation of drainage network at level 11.
• Setting network topology (i.e. nodes and link).
• Determining routing order.
• Determining cell locations for network links.
• Find drainage outlet.
• Determine stream (links) features.

Changelog

• Rohini Kumar May 2014
  • cell area calulation based on a regular lat-lon grid or on a regular X-Y coordinate system
• Robert Schweppe Jun 2018
  • refactoring and reformatting
