About this document
GIS Analysis of TIN and DEM in Hydrology by IOSRjournal is a document available to read on EtoBox.
1) The document discusses using GIS to generate a stream network and assign stream orders from elevation data. TIN and DEM are generated from contour data and used to determine flow direction and accumulation. 2) A stream network is delineated by applying a threshold to the flow accumulation raster. Stream ordering is then performed using the Strahler method where first order streams join to form second order streams and so on. 3) The results show stream networks with different numbers of orders can be
