Hi, everyone:
If I use Manning value is constant (=5, I know it is unreasonable) in HD/Resistance, that is allowed, but result is wrong.

So, I create a Manning file, total grid is 320*753, boundary band have 10 grid lines equal 5, and center grid equal 20, but it did't run.

Remark say:" you can specify a small band (2 to 4 grid lines) with a very high resistance. Manning numbers in the range 5 -10 m1/3/s have been applied successfully."( I did. But it can't run. )

And log file say:"Bed resi. file does not cover sim. period",  I don't understand what it mean.
