An existing channel is to be enlarged to increase its
capacity. The enlarged channel cross-section is shown in
Fig. below. The existing channel is of concrete
construction with a Manning's (n = 0.012), and it carries a
maximum discharge of (3 m3/s). The new channel will
also be constructed with concrete lining with a Manning's
(n = 0.012). If the total discharge after enlargement is (9
m3/s), find the normal depth and the critical depth in the
