ons de m la width: 20 = (BH)3/3 3 4.16 Manning's formula for a rectangular channel can be written as depth=0.3 1 VS n (B + 2H)2/3 slore where Q = flow (m/s), n = a roughness coefficient, B = width (m), H depth (m), and S = slope. You are applying this formula to a stream where you know that the width = 20 m and the depth = 0.3 m. Unfortunately, you know the roughness and the slope to only a + 10% precision. That is, you know that the roughness is about 0.03 with a range from 0.027 to 0.033 and the slope is 0.0003 with a range from 0.00027 to 0.00033. Use a first-order error analysis to determine the sensitivity of the flow prediction to each of these two factors. Which one should you attempt to measure with more precision? 5. 0
