Assignment 4: Basin Delineation

At first, I downloaded the files from the unm learn and made them a continuous surface using the mosaic tool from the ArcToolbox. The E177.E00 file was kept to work on and other two were removed. Then I edited the metadata and include additional information about the file. Next, I added colorized raster using symbology feature and a base map was added.

I filled the missing data using the ArctoolBox. Then I started the hydrologic part. Flow direction was created using flow direction tool under the hydrology tool. Later, flow accumulation, stream and stream network were generated. Streams were linked and turned into a polyline. After that outlines were defined that appeared as dot on the polyline. Finally, I delineated the watershed and converted the raster into polygons.
