Monitoring flood area at a river catchment
Abstract
For the past 10 years, flood had happened in Perlis many times. The area that
involves with flood are Kangar, Chuping, Arau and Padang Besar. The title of this study
is monitoring flood potential area at a river catchment. The objectives of this study are to
determine the flood potential area and analyzing Total Suspended Solid (TSS) of river
catchment. In this study, 6 points have been chosen. The 6 points is located at Sungai
Jerneh, Sungai Panggas Limau, Sungai Serai, Sungai Buloh, Sungai Serai near a sugar
cane area and Panggas river. The area of river catchment is near Bukit Keteri and
Chuping. The parameters of this study are turbidity, total suspended solids and current
flow. Equipments that were used are current meter, global positioning system, 2100N
Turbidimeter and vacuum pump. The method of this study is first search the location of
the river that is decided in the map. Then site visit of the river will be done at the 6
locations. After the site visit analysis is being done. The analysis is divided into two
which are ex-situ and in-situ. Ex-situ means water sample that is taken is measured in lab
while In-situ that is the measurement taken at the site. From the total suspended solids
result the highest TSS reading is 25 mg/L at Sungai Panggas on week 8. The lowest TSS
reading is 0.5 mg/L at Sungai Panggas on week 7. For turbidity in week 6 it rains heavily
if compared to other weeks. Thus, it shows the highest turbidity for 6 points on week 6 if
compared with other weeks. For week 6 the reading of turbidity is 30.5 NTU at Sungai
Serai near a sugar cane area, 53.3 NTU at Sungap Panggas, 15.8 NTU at Sungai Jerneh
2, 32.4 NTU at Sungai Jerneh, 39.3 NTU at Sungai Buloh and finally 66.2 NTU at
Sungai Serai.
