The p
resent study deals
with
the
supercritical flow
characteristics and the effort has been made to
verify analytical
and
empirical relations based on extensive experimentation for different characteristics
namely
:
sequent depth ratio (h
2
/h
1
),
e
fficiency of jump (E
2
/E
1
), relative height of jump (h
j
/E
1
) and
relative
length of jump (L
j
/h
2
).
Also, the existing models for different
channel conditions are discussed;
significance of Froude number an
d Reynolds number for a
range of velocity mentioned in literatures are
highlighted
; m
odels proposed by
different
aut
hor
s
and
its
validation
were
also
explained
.
Undular jump
formation and the role of turbulent boundary layer
were also
explained for Froude number
varying
between
1.3
-
2.3
.
All the
characteristics
are found suitable with existing relations and can be used
a
s
guidelines
for
the analysis
of
different
channel
and
channel
conditions
