SRTM elevation data¶

Finding a streamflow gauge¶

For this workshop, we need to find a watershed that has a streamflow gauge at its outlet for calibration purposes. Go to StreamStats and search for 02331600, which is the name of a United States Geological Survey (USGS) streamflow gauge.

Copy the latitude and longitude to a text editor. We will need this information later.

Select Georgia and delineate a watershed at just the downstream cell of the gauge. Download the watershed Shapefile as streamstats_02331600_watershed.zip.

Downloading the SRTM DEM¶

Go to EarthExplorer and zoom to the area of the watershed above. Draw a polygon that entirely covers the watershed.

We will use the SRTM DEM. Click Data Sets and search for “SRTM 1 arc-second”.
