Consider flow along a 1000 m overland flow element with n=0.2.
1. Rewrite the finite difference approximation so it can be used to model overland
flow.
2. If the element is divided into 5 grid units, what is 4x?
3. What is the celerity at a representative depth of 3 cm?
4. What maximum timestep can be used to solve this flow?
5. The design storm intensity [mm/hr] is given by the normal distribution below. Find
the values ie,i and ie,i+1 for ti+1=1.5 hr.
ie(t) = 10 exp
(t-1.5)2)
0.25
