basis should be replaced by basic

 

There is a Θ missing in the equation, before the [

 

 

change the dashed line to dotted

 

Area should be 20.12, R is 0.1841, Q is 13.72

 

Main channel:

A is 10.12, P is 9.376, R is 1.079, V is 2.218, Q is 22.44

Total discharge is 26.98

 

In answer, 2.26 should be 2.6

"opposition current" should be "opposing current"

 

The control volume is enclosed by lines perpendicular to the bed and not vertical as shown

vx should be vX

 

"using the Cauchy-Schwarz inequality" should be replaced by "writing vX as sum of mean velocity, V, and deviation v' "

 

Replace by this.

 

 

At the end of the solution, the phrase "As seen in Example 3.2" should be deleted

 

"Froude number will increase" should be "Froude number will decrease"

 

Eq. (3.33) should be Eq. (3.23)

 

 

The y-axis labels 1 and 10 should be lowered

 

(Eq. 3.38) should be Eq. (3.38)

9.5 m)3 should be 9.5 m3)

 

t should be the greek letter l

 

P_w should be shown as the pressure force on weir

 

The upper and lower nappe should be labeled

 

The table is missing a row. Correct table is here.

 

"Table 4.2" should be "Table 4.1"

The line shown at T=1 should be at T=3. See here.

 

exp(-0.05T) should be exp(-0.5T). The value of h should be 6.5 mm, instead of 0.7 mm.

 

 

The figure for J2 is incorrect (actually the same figure is repeated). The correct figure is here.

After Eq. (8.48), "Eq. (8.35)" should be "Eq. (8.48)"

 

The factor [1/{(1+m2)sin2}] is incorrect. The correct expression is same as that in Eq. (8.48)

  1. Footnote 15

Dr. Nosrat Maghsoudi

The mass released is 100 tonnes NOT 100 kg. Accordingly, in the solutions: Ex. 9.1: mp=100 tonne, Ex. 9.3: mpl=2x1010 mg/m, Ex. 9.4: mpp=2x107 mg/m2. The concentration units of mg/l are correct!

 

Total mass is mpp By not mpp as printed

 

Missing: it said that velocity and dispersion are assumed to be constant
