Concepts of Flood Control

Flooding is a temporary overflow of water that submerges or covers the the usually dry land. It can also be defined as the overflow of the excess amount of water that covers a huge area of land which is normally dry.

FLOOD---ESTIMATION AND CONTROL

(a) Explain the following terms with reference to frequency studies:
(i) Annual series
(ii) Partial duration series
(iii) Recurrence interval
(b) At a particular gauging station, the annual maximum floods are recorded from 1951 to 1975.
The mean and standard deviation of these floods are 310.24 cumec and 110.54 cumec, respec-
tively. Assuming that the flood series follow Gumbel's distribution, determine the flood
magnitudes for the recurrence intervals of 200, 100, 50 and 25 years. Plot these points on the
Gumbel's probability paper.

Two communities, A and B, are found on two opposite sides of flowing river with a 9.10 m3 /s rate of volumetric flow, an uniform average speed of 0.25 m/s, an average depth of 4.0 m, an average temperature of 13°C, a chloride concentration of 8.0 mg/L, a 5.0 mg/L concentration of ultimate BOD, and an 8.0 mg/L concentration of dissolved oxygen. Both communities continuously discharge wastewater at the same point in the river where instantaneous mixing is assumed. The discharge of community A, which has an ultimate BOD of 48.2 mg/L and a dissolved oxygen concentration of 2.50 mg/L, is 2.10 m3 /s. On the other hand, community B discharges 1.80 m3 /s of wastewater, which has an ultimate BOD of 62.9 mg/L and a dissolved oxygen concentration of 1.50 mg/L. Just downstream of the downfall of both point sources, the deoxygenation rate constant is observed to be 0.22 day-1 .
