   Using archydro tool with GIS


  1. Open ArcMap and a new blank map.

    • Do not open an existing map file. Remember to save your work frequently. Save map (.mxd).

  2. Load all DEMs into ArcMap

    • Go to File > Add Data> Add Data, select your DEM folder (Upper left). If asked to build pyramids say Yes.

  3. Select the study area coordinate system

    • Right clic on Layers> Properties> Coordinate System, chose Projected Coordinate Systems - UTM - WGS 1984 - Southern Hemisphere - WGS 1984 UTM Zone 19S. Then clic on Apply.
