A FlowMaster report is given on the following page. This is the output from the design of a riprap lined channel. Some of the information has been deleted. Use the data given in the report and your expert knowledge of open channel flow to answer the following questions.

a$)$ Is the flow suberitical or supercritical? How can you tell? $(4$ points$)$

b$)$ What is the discharge in the channel? $(3$ points$)$

c$)$ What is the Manning's $n$ for the channel? $(4$ points$)$

d$)$ What is the size of the riprap in the channel? $(3$ points$)$

e$)$ If the riprap is very angular, then does the channel meet the criteria for a balanced design? $(5$ points$)$

f$)$ Will the channel erode with this discharge? $(6$ points$)$A FlowMaster report is given on the following page. This is the output from the design of a riprap lined channel.
