Hydrologic analysis of a watershed Problem2: The unit hydrograph is the direct runoff generated by 1 unit (I mm in this problem) of excess rainfall. The one-hour unit hydrograph of a watershed is given by: 4 Time (hour) -0.9 U0.4 U0.2 0.0 0.0 U-0.6 Unit hydrograph (m/s/mm) (a) The 100-year storm over the watershed has the following excess rainfall pulses: Fromt 0 to 1 hour, P45 mm From t I to 2 hours, P20 From t = 2 to 3...

A 23-acre watershed undergoes development. The runoff
coefficients (C) for pre-development and post-development
conditions are 0.2 and 0.4, respectively. The pre-development and
post-development times of concentration are 0.25 and 0.15 hour,
respectively. Estimate the depth (in.) and volume (acre-ft) of
detention storage required using the loss-of-natural-storage
method. Assume that the IDF curve shown in Figure 2.4 applies and
that the design policy requires control for a 10-year event. (Use
Triangular Hydrograph Method)

Use Peterson's fitted on (equation below) for a value of a. Modification factors shall be applied for the following of an axial force amplitude P, 16kN applied along with a mean force of Pm dimensions, as in Figu...
For
Both Figures:
Is h[n] symmetrical or asymmetrical?
How is the magnitude response?
Is the phase response linear? Why?
My current answer is:
For Figure A: symmetrical, not sure about mag response, linear
phase response
For Figure B: asymmetrical, not sure about mag response,
non-linear phase response because of the slight delay in the
wrapped phase response?
A full explanation for the magnitude and phase response,
please.

Problem 2: Designing Culverts Under a Bridge on El Rio de las Aguas Torenciales A 100-year stom event is being considered in order to design the culverts under a bridge. Figure 3 shows the storm event that may fall on the rural watershed of area 3.2 Km that drains into El Rio de las Aguas Torenciales. It generates runoff all over the watershed. The runoff flows into the river towards the ast point A (Figure 4) in the watershed where...

Veloety Y. Tme Use the equation of the curve to find the accelerating Note: The quantity that will give g is (12) the coefficient of the t? term. In addition, in order to convert this valúe from units of em/0.017s/0.17s to units of cm/s2, this number must by multiplied by 60 X 6- 360 3.
