Hyetographs and hydrographs A rainfall hyetograph is a plot of rainfall depth or
intensity as a function of time. A discharge hydrograph is a graphical
representation of flow rate as a function of time at a given location on a river. Two
types of ...
Convolution is the process of deriving surface runoff hydrograph from effective
rainfall hyetograph and unit hydrograph. The steps of runoff hydrograph
computations are as follows: 1) Determine time step of computations (approx.
0.29 tL), At ...

Hydrology and Soil Conservation Engineering: Including ...
The hyetograph is a discrete representation of a rainfall hydrograph. Such
representations of rainfall data are very convenient for hydrological analysis,
especially for the estimation of design storms for prediction of floods. A
hyetograph is ...

(b) Assuming the initial loss is 10 mm, determine the value of f index (in mm/hr)
and the corresponding effective rainfall intensity hyetograph (in mm/hr). 8.3.1
Determine the 4-hr unit hydrograph using the following data for a watershed
having a ...
0.4r A hyetograph is a plot of the intensity of rainfall against the time interval. The
hyetograph is derived from the mass curve and is usually represented as a bar
chart (Fig. 2.10). It is a very convenient way of representing the characteristics of
a ...

Step 3: Develop the Rainfall Hyetograph. The rainfall hyetograph may be
developed in several ways. For example, perhaps the time distribution of rainfall
has been determined for the study area. Such is the case in 1llinois (Huff, 1967),
where ...

Urban Stormwater Hydrology: A Guide to Engineering Calculations
tain a Huff design hyetograph. Let the depth and the duration of the design
rainfall be PT = 5 inches and td = 2 hours, respectively. Suppose the first quartile
distribution is representative of the local rainfall data. Let us find the intensity
between ...

The hyetographs obtained from the two methods should become identical as the
time increment used in the synthetic block method approaches zero if the
intensity sequence of the block hyetograph is chosen properly. Example 2.9 Let ...

A Text Book of Hydrology
For the construction of a rainfall hyetograph it is not always necessary to
determine the instantaneous intensities by drawing tangents to the mass curve.
Usually a constant time interval is selected and average intensities in successive
time ...
4.5 5 3.9 HYETOGRAPH AND MASS CURVE OF RAINFALL Hyetograph is the
plot of rainfall intensity in mm/hr or cm/hr of a series of rainfall against time
occurring in a particular catchment. It is also called rainfall hyetograph. It is a
discrete ...
