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). H? lw H H? Weir The flow across the weir, Qw (m³/s), can be computed as Qw = CwBw ?8 (1) ¹2H?³/2 -(¹) where Cw= a weir coefficient (dimensionless), Bw = the weir width (m), and g = acceleration due to gravity (m/s2). Cw can be determined using the weir height (Hw) as Cw=1.125?2+Hy/Hw 1+Hh/Hw given g = 9.81 m/s², Hw= 0.8 m, Bw= 8 m, and Qw=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 11.25 m.
