Question

Hydrology-SLOPE-AREA METHOD

During a flood flow the depth of water in a 12 m wide rectangular channel was found to be 3.5 m and 3.0 m at two sections 300 m apart. The drop in the water-surface elevation was found to be 0.15 m. Assuming Manning’s coefficient to be 0.025, estimate the flood discharge through the channel.

SLOPE-AREA METHOD
During a flood flow the depth of water in a 12 m wide rectangular channel
was found to be 3.5 m and 3.0 m at two sections 300 m apart. The drop in
the water-surface elevation was found to be 0.15 m. Assuming Manning's
coefficient to be 0.025, estimate the flood discharge through the channel.
