CTC 440 - Homework 13 (Watershed Area)

1. Define the watershed and determine the drainage area (in acres, square miles, and hectares) of the point marked with an "x" on the USGS map (1:24,000 scale or 1"=2000'; contour interval = 6m) handed out class.

Determine the approximate slope of the above drainage channel

Will do in class; do not turn in for homework.

2. Think of a drainage structure underneath a road (near your home or work, etc). Download the appropriate USGS map, capture an image of the watershed, print it, delineate the watershed area and determine the area. Do the delineation on your own and then use streamstats for comparison and verification; print streamstats data.
