HydroGeoSphere/Surface Flow (Initial)

Initial water depth

 * 1) val Initial water depth.

Chosen surface flow nodes are assigned an initial depth value.
 * &bull; &bull; &bull;

Initial water depth from gb file

 * 1) fname Name of the GRID BUILDER ascii-formatted nodal properties file gb_prefix.ascii nprop.description which contains the initial water depth data.

This instruction assumes that the surface flow domain covers the entire top of the 3-D domain, and contains NN2D (number of nodes in the 2-D slice) nodes. All surface flow media nodes (see Section 5.8.1) are assigned an initial water depth value which is read from file fname. This is an ascii formatted file, with the water depth values listed in order from node 1 to NN2D.
