Unformatted text preview: 2 Where , n-roughness coefficient , B- width (m) , H- depth (m) and S- slope . You are applying this formula to a stream where you know the width is 20 m and the depth is 0.3 m. Unfortunately, you know that the roughness and the slope to only precision. That is you know that the roughness is about 0.03 with a range 0.027 to 0.33 and the slope is 0.0003 with a range from 0.00027 to 0.00033. Use a first order error analysis to determine the error estimation of the flow and determine the sensitivity of the flow prediction to each of the two factors. Which one should you attempt to measure with more precessions....
