| Summary: | Total Suspended Solid (fSS) is important as one of the parameters that can be influenced by a stream power which will affect the ecological condition of the system. Therefore, the objectives of this study were to improve understanding in TSS variation along Sampadi River and provide fundamental data for monitoring purposes as Sampadi
River is important for fisheries activities among the local
people. Six sampling trips for samples collection were conductecl at 12 selected stations along 5ampadi River during high (February 25; October 22; and November 11) and low (February 25; May 21; and November 11) tide of Spring
tide. Water samples for TSS analysis were collected in triplicates from the subsurface. Transparency and turbidity
data were recorded in-situ. '5S values along Sampadi River
during the study period ranged from 26.33±3.511!lgl·1 at station 1 to .04.33±7.57 mgt· 1 at station 13 during low tide. The range increased during high tide from 27.oo±13.89
mgl-1 at station 10 in February to 160.00±1.15 at station 12
in November. TSS at station 13 is significandy higher compared to all other stations during low tide. However during high tide, the TSS value at Station 12 is significandy higher compared to all stations but do not have
significant difference as compared to station 13. Turbidity
values range from 2.77±0.06 NTU at station 3 in May to
92.6±0.00
NTU
at
station
13
in
February.
However
the
range
of
values
decreases
slighdy
during
high
tide,
from
2.03±0.06
NTU
at
station
6
in
October
to
52.03±3.63
NTU
at
station
12
in
November.
Transparency,
measured
in
centimeter
ranged
from
15.33±0.58
em
at
station
13
in
February
to
119.33±1.15
em
at
station
3
in
November.
While
during
high
tide
the
transparency
value
increased
to
28.67±1.15
em
to
150.33±0.58
at
station
3
in
October
during
high
tide.
This
suggests
that
TSS
variation
along
Sampadi
River
support
the
theory
of
turbidity
maximum
zone
which
normally
occurred
at
up
or
down
estuary.
Based
on
TSS
values
as
compared
to
the
Interim
National
Water
Quality
Index
(INWQS)
for
Malaysia
of
the
Department
of
Environment,
Sampadi
River
falls
into
class
III
which
is
within
range
for
common,
ofeconomic
value
and
tolerant
species. |
