| pe— (a) Compare the course of the Bighorn River between points A and B with that of its tributary between points Cand D (Fig. 11.4). [ill in the table below. Note: To measure the true total channel length, especially when it meanders, you can use a ruler or string. With a ruler, measure each straight segment separately, recording each length, and then add them up at the end and convert to miles using the scale on the map. With string, trace the river and tape down the string at each place where it bends. At the end, remove the tape, straighten the string, and measure the length of string you used.

Estimating Potentiai Fiood Probiems Section: pate: Name: Course: The streams shown on maps throughout this chapter are all subject to flooding, but the potential problems faced by cities along the banks of different streams are not the same. In this exercise, you will use the maps from this chapter to answer the following questions about potential problems caused by floods. (a) Refer to the maps in Figures 11.9, 11.11, and 11.12. For which of these streams would a flood 20 feet higher than the current stream channel cause damage to human-built structures and roads? In each case, describe what would happen.
