Answer:
1) The probability to fill the notch is greater than 95%
2) The probability to fill the middle terrace is 5 to 25 percent
Explanation:
1) The calculated discharge, , to fill the notch is given by the relation;
= Width × Depth × Velocity = 8 × 5 × 0.5 = 20 m³/s
From the Annual Exceedance Probability chart, the exceedance probability is greater than 95%, therefore, the probability to fill the notch is greater than 95%
2) The calculated discharge, , to fill the middle terrace is given by the relation;
= Width of middle terrace × Depth of middle terrace × Velocity of middle terrace +
= 35 × 2 × 1.4 + 20 = 118 m³/s
From the Annual Exceedance Probability chart, the probability to fill the middle terrace is 5 to 25 percent.
