Test: Flood Routing - 1 - Question 4

In routing a flood through a reach, the point of intersection of inflow and outflow hydrographs coincides with the peak of outflow hydrograph

Test: Flood Routing - 1 - Question 5

Which of the following is a proper reservoir-routing equation?

Test: Flood Routing - 1 - Question 6

The Muskingum method of flood routing is a

Detailed Solution for Test: Flood Routing - 1 - Question 6

In reservoir routing, the storage is a unique function of outflow discharge, S = f(Q).
However, in channel routing the storage is a function of both outflow and inflow discharge and hence a different routing method is needed from muskingum method of hydrological channel routing storage is given by,

Test: Flood Routing - 1 - Question 7

The Muskingum method of flood routing assumes the storage S is related to inflow rate I and outflow rate Q of a reach as S =

Detailed Solution for Test: Flood Routing - 1 - Question 7

For a given channel reach by selecting a routing interval Δt and using the Muskingum equation, the change in storage is,
S2 - S1 = k(xI2 - I1) + 1 - x(Q2 - Q1)
Where suffixes 1 and 2 refer to the conditions before and after the time interval Δt.

Test: Flood Routing - 1 - Question 8

The Muskingum method of flood routing gives Q2 = C0I2 + C1I1 + C2Q1. The coefficients in this equation will have values such that

Detailed Solution for Test: Flood Routing - 1 - Question 8


Test: Flood Routing - 1 - Question 9

The Muskingum channel routing equation is written for the outflow from the reach Q in terms of the inflow I and coefficients C0, C1 and C2 as

Test: Flood Routing - 1 - Question 10

In the Muskingum method of channel routing the routing equation is written as Q2 = C0I2 + C1I1 + C2Q1. If the coefficients K = 12 h and x = 0.15 and the time step for routing Δt = 4 hr, the coefficient C0 is
