Starting from upstream to downstream, the following data have been collected for a 1.5-km-long portion of a natural river. Determine the equivalent bed slope and the discharge in the river if constant a in equation (10.30) is equal to 12.6. Also determine the time required by a floating object to cross this portion of the river.
