Assessments of sedimentation problem for river catchment management in Terengganu River, Malaysia
Terengganu River experienced deterioration in water quality, resulting from the sedimentation, anthropogenic, geomorphology problems and unsustainable development management around the river basin. This study was implemented to prove the sedimentation problem especially the formation of total sus...

description |
Terengganu River experienced deterioration in water quality, resulting from the sedimentation,
anthropogenic, geomorphology problems and unsustainable development management around the river
basin. This study was implemented to prove the sedimentation problem especially the formation of total
suspended solid (TSS) and the bed sediment grains size in this areas. The technique of analysis of primary
data obtained which determine according with the procedure of Gerald & Kenneth and the phi (ϕ) value
in this study using the scale Udden - Wentworth which included median, mean, standard deviation,
skewness, and kurtosis. As a result, the highest TSS up to 67.2 mg/L (Wet Season) and 128.2 mg/L (Dry
Season) which is categorized under the class II and class III respectively, based on the National Water
Quality Standard (NWQS). The size of sediment falls between phi -0.1 to phi -1.0 which classified as
rough and very rough especially around the stations which near the sand mining area activities. This study
also presented the application of selected chemometric techniques such as Agglomerative Hierarchical
Clustering (AHC). The AHC enabled to group 19 monitoring sites into a few groups of sedimentation
problem factors (industry and urban socioeconomic, sand mining activities, agricultural activity and
urban/domestic sewage). For overall, the contributors of sedimentation problems are from unsustainable
land use such as sand mining activities which effectively trapping the bed sediments, backflow that carries
out high sediments, as well as sedimentation produced due to the river bank erosion. |
