For an irrigation project for an area of 10.000 km2 water has to be transported to compensate for natural evaporation. The total evaporation per year is the equivalent to a yearly rainfall of 30 cm. The water flows through an open channel of 100 km length from a lake 100 m higher than the irrigation area. The transport channel is 3 m deep but the water level is just 2 m. The channel has a rectangular shape and a friction factor of 4.10-3.
Make an estimate about how wide the channel should be assuming steady-state conditions. The width of the channel is significantly larger compared to the water level height in the channel.
