The runoff data at a stream gauging station for a flood are
given below.
The drainage area is 40 km2. The duration of rainfall
was 3 hours.
Derive the 3-hour unit hydrograph for the basin and plot
the same.
State the peak of the unit hydrograph you
derive

the ordinates of a 6-h unit hydrograph for a particular
catchment are 0,10,30,50,40,30,20,10 and 0 m3/s (values at 3 hourly
intervals). the effective rainfall depth of a particular storm was
28 mm. assume a constant base flow of 3 m3/s. what is the
streamflow at the end of the third time interval?

A 1” of rainfall excess falls on to a determined watershed in 1
hour resulting in the following unit hydrograph. Estimate the
hydrograph if you know that the precipitation event resulted in the
rainfall excess as shown in the second table. Take the base flow
value as 0.25 inch/hour.

For a given basin, the following are the infiltration capacity
rates at various time intervals after the beginning of the
storm.
Make a plot of the f-curve and establish an equation of the form
developed by Horton for infiltration curve.
Also determine the total rain and the excess rain
(runoff).

3. (Lesson 11) Use Minitab Express to conduct a
chi-square test to determine if there is a relationship between
gender and whether the student said that they would prefer to win
an Academy Award, Nobel Prize, or Olympic Medal. Use the

2. (Lesson 11) The “Year” variable represents whether
each student identified as a first-year student, sophomore, junior,
or senior. Use Minitab Express to conduct a chi-square test to

A physiological experiment was concluded to study the effect of
various factors on a pulse rate. The participants took their own
pulse. They then were asked to flip a coin. If their coin came up
head, they were to run in place for 1 minute. Then everyone took
their own pulse again. The dataset pulse.txt, available from
Moodle, contains the following variables: ROW- id numbers, from 1
to 92; PULSE1- first pulse rate; PULSE2- second pulse rate;
RAN-1=ran in place,...

You are the foreman of the Bar-S cattle ranch in Colorado. A
neighboring ranch has calves for sale, and you are going to buy
some calves to add to the Bar-S herd. How much should a healthy
calf weigh? Let x be the age of the calf (in weeks), and
let y be the weight of the calf (in kilograms).
