are
useful
in
both
classroom
and
professional
applications.
Extensive
on-line
documentation
is
available
for
all
programs.
This
program
allows
for
the
calculation
of
surface
profiles
of
trapezoidal
channels
using
both
the
direct
step
method
and
the
standard
step
method.
Normal

conditions
can
also
be
calculated.
This
is
a
very
handy
tool
for
the
calculation
of
these

The
US

(now
the
NRCS
-

Service)
computer
program
for
Project
Formulation
Hydrology.
TR-20
was
formulated
to
develop
runoff
hydrographs,
route
hydrographs
through
both
channel
reaches
and
reservoirs,
and
combine
or
separate
hydrographs
at
confluences.
The
program
is
designed
to
make
multiple
analyses
in
a
single
run
so
that
various
alternatives
can
be
evaluated
in
one
pass
of
through
the

| TR-55,
Urban
Hydrology
for
Small
Watersheds,
Version
2.0 |
This
Rainfall
Runoff
Model
was
developed
by
the
US
Soil
Conservation
Service,
now
known
as
the
Natural
Resources
Conservation
Service
(NRCS).
TR-55
presents
simplified
procedures
to
calculate
storm
runoff
volume,
peak
rate
of
discharge,
hydrographs,
and
storage
volumes
required
for
floodwater
reservoirs.
These
procedures
are
applicable
in
small
watersheds,
especially
urbanizing
watersheds,
in
the
United
States.
The
primary
functions
of
the
program
are
for
peak
runoff
computations
using
the
Graphical
Peak
Discharge
Method,
the
Tabular
Peak
Discharge
Method
and
Temporary
Storage.
Support
functions
include
the
computation
of
the
runoff
curve
number
(CN),
the
Time
of
concentration
(Tc)
and
travel
time
through
a
subarea
(Tt).
Limits:
NRCS
type
distributions,
24-hour
duration
rainfall,
10
subwatersheds,
minimum
0.1
hour
and
maximum
10-hour
time
of
concentration.
This
Rainfall
Runoff
Model
was
developed
by
the
US
Environmental
Protection
Agency.
It
is
a
large,
complex
model
capable
of
modeling
the
movement
of
precipitation
and
pollutants
from
the
ground
surface
through
pipe
and
channel
networks,
storage
treatment
units,
and
finally
to
receiving
waters.
Both
single
event
and
continuous
simulation
can
be
performed
on
catchments
having
storm
sewers
and
natural
drainage,
for
prediction
of
flows,
stages
and
pollutant
concentrations.
This
is
the
latest
version
of
the
program
and
is
downloaded
from
the
Oregon
State
University
FTP
Site.

This
utility
program
will
take
a
cumulative
rainfall
total
(in
inches
or
centimeters)
and
distribute
it
incrementally
over
a
set
storm
time
period.
It
will
distribute
rainfall
over
SCS
Type
I,
II,
or
III
storm
patterns
or
a
user
specified
pattern.
The
output
is
a

of

rainfall
depths.
