This was another project I completed for my CE 508 class at Purdue. For this project, we were tasked with delineating watersheds (blue polygons) in the greater Houston area and analyzing the results with respect to stream length (yellow lines) and total rainfall data from hurricane Harvey (green circles). The watersheds were delineated by using the Flow Direction and Flow Accumulation tool to visualize streams, Reclassify to binarize the data, Raster to Polylines to convert the stream raster into polylines, and the Watershed tool to create watershed polygons. Due to the area of interest being on the coast, there were numerous instances of bad data, so I had to check the sinks in the flow direction raster and fill them accordingly to clean the data. Once the watersheds and streams were delineated, it was possible to draw conclusions about correlation between stream length and total rainfall and watershed size and total rainfall. This project, while difficult, proved extremely useful as I used this as a reference for my Echo Lake and Duhernal Lake pollutant loading ArcGIS projects and Kleinfelder the following summer.
