CASE IV: AUTOMATED METHODS USING A TIN
In Case IV a TIN is created in WMS for Area 2, and the watersheds are delineated in WMS. The TIN is made using the conceptual model approach and interpolating points from a 30 meter DEM. WMS has the ability to create and delineate TINs. Once the TIN has been delineated, geometric basin attributes may be computed.
The steps to create a TIN using the conceptual model approach involve digitizing points from a DRG (the same DRG as used in Case II). This was done by opening the TIN module in WMS, and selecting edit vertex points from Vertex
Options in the TIN are entered based entered using DRG
menu. Once the Vertex Options box is open, point
contour lines as a reference
4.17 shows of elevation.
