-Determine the upstream depth, H, using the modified secant method with = 10⁵. (Round the final answer to four decimal places.)The value of the upstream depth is _____ m.

-Determine the upstream depth, H, using fixed-point iteration. (Round the final answer to four decimal places.)The value of the upstream depth is ______ m.

Required information The figure given below shows a side view of a broad crested weir. The symbols shown in the figure below are defined as: Hw= the height of the weir (m), Hh= the head above the weir (m), and H= Hw+ Hh-the depth of the river upstream of the weir (m) Welr The flow across the weir, Qw (m3/s), can be computed as where Cw-a weir coefficient (dimensionless), Bw-the weir width (m), and g= acceleration due to gravity (m/sz). Cw can be determined using the weir height (Hw as given g- 9.81 m/s, Hw 0.8 m, Bw 8 m, and aw 1.3 m3/s. Use the initial guess of 0.5Hw Determine the upstream depth, H, using the MATLAB function fzero. (Round the final answer to four decimal places.) The value of the upstream depth is m.
