Probability plotA bridge will be built over the Meherrin River near the site that the discharge measurements were taken for the log-normal probability plot below. The service life of the bridge is 40 years. If a design discharge of 23,000 cfs is used for the bridge: (a) what is the probability that the bridge will be flooded in any one year? (b) What is the probability that the bridge will be flooded at least once over its service life? (Note: just focus on the “theoretical line” in the plot)
Hydrology The following table gives values of measured discharges at a stream gauging site in a year. Upstream of the gauging site a weir built across the stream diverts 4.0 Mm^3 and 1.5 Mm^3 of water per month for irrigation and for use in an industry respectively. The return flows from the irrigation is estimated as 0.50 Mm^3 and from the industry at 0.40 Mm3 reaching the stream upstream of the gauging site. Estimate the natural flow. If the catchment area is 200 km^2 and the average annual rainfall is 200 cm, determine the runoff-rainfall ratio.
