CatchmentNamData Class

A lumped, conceptual rainfall-runoff model, simulating the overland-, inter-, and base-flow components as a function of the moisture contents in four storages; snow, surface, root-zone and ground water.

This class contains data and parameters for setting up a NAM model, and is as such a data class only. Computational variables are not included in this class. It can be used to explore data and parameters required when setting up the NAM model.

CatchmentGeometry Get and set the list of coordinates of the catchment

The sequence of coordinates can represent one or more polygons. It is interpreted as follows:

  • Polygons are stored in sequence.
  • A polygon is stored with the outer ring first, and any holes following immediately.
  • Any polygon ring (outer or inner) is represented as a string of coordinates, starting and ending with the same coordinate.
  • Any polygon that is clockwise is assumed to be an outer polygon.
  • Any polygon that is counter-clockwise is assumed to be a hole in the most recent outer polygon. A hole must be fully contained by the most recent outer polygon and not overlap other holes.
