Question
We are monitoring water flow in an open rectangular channel. The inflow and outflow are measured using weirs installed at both ends of a 1000 m long channel segment. The water height in the channel at the start of the measurement period is 0.3 m. The measured inflow rate (per unit width) during the 1 min measurement period is 5 m2/s. The measured outflow rate (per unit width) during the same period is 4 m2/s. Calculate the new water height in the channel at the end of the 1 min measurement period (assuming no rainfall, evaporation, or infiltration).
Explanation / Answer
0.24 m
