Time and time related variables in engineering

Time is the event progression starting from past to present and then, future statistically. The time-related variable is any particular value in relation to time to assess its changes on a specified (XY) plane.

Question

A lined rectangular channel with Manning's n =
0.015 is 5 m wide and has a flow depth of 2m
with the bed slope of 1 in 1600. Retaining the
rectangular shape of channel section and the same
total area of lining, to what maximum extent can
the discharge be increased without changing the
bed slope? Does the flow change from sub critical
to super critical state by this increase in discharge.
