Problem $3\mathrm{.}26$

Find the drainage density for the following watersheds. The reach lengths, in miles, are

shown.

Problem $3\mathrm{.}27$

For the watershed of Problem $3\mathrm{.}26($a$),$ identify the order of each stream segment, find

the actual number of streams for each order and compute the bifurcation ratio. Compute

the expected number of streams of each order. For the watershed of Problem $3\mathrm{.}26($b$),$

identify the order of each stream segment, find the actual number of streams for each

order, and compute the bifurcation ratio. Compute the expected number of streams of

each order. Answer the entire Problem $3\mathrm{.}27.$
