'Maximum Q(lOO) that a brow ditch will handle is for Area 3=7.10 cfs. Therefore proposed brow ditch can
handle the runoffS.
C) Size the ripraps. From the equation Q=A V, we can get V~Q/A
Use the biggest Q=7.1O cfs (Area 3)
Therefore V=7.10/1.25 = 5.68 fps
From the "Green Book" Standard Specifications for Public Works Construction" 1988 edition, we get
the size of the riprap.

INSTRUCTIONS FOR PATION-"-L ~=THOD HYD?.CJLOGY CALCULATIONS
(Based on the Rational Forrr~la, Q ~ CIA)
1. On map of drainage area, dra~ drainage system ~~d block off subareas
tributary to it.
2. Deterrnine the initial ti!:'~e of concentratio:1., lIT II , using plate 0-3.
The initial area should be less th~~ 10 acres, have a flow path of
less than 1,000 feet, and be t~e most upstre~~ subarea.
3. using the time of concentration, determine "Ill, intensity of rain-
fall in inches per hour, fro~ the appropriate intensity-duration
curve for the particular area under study. For areas where stan-
dard curves are available 1 use Plates 0-4.1 and D-4. 2" to reproduce
the standard curve. For areas where curves have not been published
by the oistrict, use Plates 0-4,3 through 0-4.7 to develop a suit-
able intensity-duration curve.
4. Detennine "ell, the coefficient of runoff, using the runoff coeffi-
cient curve which corresponds as closely as possible ~ith the soil,
cover type and development of the drainage area. Standard curves
(Plates 0-5.1 through 0-5.4) have been developed by the oistrict
for the common case of urban landscaping type cover. Where these
curves are not applicable, curves may be developed using Plates
0-5.5 through 0-5,8.
5. Determine "All, the area of the subarea in acres.
6. Compute Q ~ CIA for the subarea.
7. Heasure the length of flow to the point of inflow of the next sub-
area downstrea~. Determine the velocity of flow in this reach for
the peak Q in the type of conveyance being considered (natural
channel, street, pipe, or open channel), using the tabling aids on
Plates 0-6 through 0-9.
using the reach length and velocity determined above, compute the
travel time, and add this time to the time of concentration for the
previous subarea to determine a new time of concentration.
8. Calculate Q for L~e new subarea, using steps 3 through 6 and the
new time of concentration. Determine "Qp", the peak Q for all sub-
areas tributary to the system to this point by adding Q for the
new subarea to the sili~ation of Q for all upstream subareas. Deter-
nine the time of concentratio~ for L~e next subarea downstre~ using
Step 7. Continue tabling dO~TIstrea~ in similar fashion until a
junction with a lateral drain is reached.
