The sedimentation study on the upstream reach of Pahang River is located in the Bentong River Basin. The detail hydrographic survey for each river in the Bentong River Basin was carried out in May 2016. Nine stations were selected to represent the sediment concentration at Bentong River, Pahang, Malaysia. Bentong River Basin is one of the river catchment in Pahang River Basin, Malaysia. Before this, Bentong River deterioration in water quality, resulting from the sedimentation 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) in the Bentong River. There are two important parameters were quantified in this study such as the concentration of suspended solid (mg/L) and the river discharge (Q) values (m³/s). The method used in this study to analysis the concentration of TSS using Gravimetric Method. The result showed the sedimentation in the Bentong River was unstable and the highest of TSS up to 367.6 mg/L that is categorized under the class V which > 300 mg/L based on the National Water Quality Standard (NWQS) result showed the coefficient correlation between the observed Q and the TSS concentration in the Bentong River is significant R² = 0.919, there are strong positive relationship between TSS concentration production and the river discharge value in the Bentong River. The study found that the contributors to the high sedimentation problems resulting from the sediments generated from the unsustainable land use, which effectively trapping the bed sediments, rainfall intensity, backflow that carries out high sediments as well as sedimentation produced due to the river bank erosion.

This study applied four hydrology parameters. The findings from Principal Component Analysis confirmed that all selected parameters were significant to be taken as main tools for further analysis with result of R 2 > 0.7. SPC set up a new control limit for all selected parameters in the study area. For those data within or beyond the Upper Control Limit value, it was being considered as high risk for flood occurrence. New flood risk index within range from 0-100 was calculated using a combination of new algebraic equation and control limit values obtained from SPC analysis as variable. The accuracy of FRI was tested using ANN.The result showed the accuracy of FRI was more than 90%. It can be stipulated that the combination of chemometric techniques and SPC can produce a new standard FRI which is cost effective, accurate and flexible to be applied for the purpose of flood risk control in tropical area.

“…For the other years such as the year 2003, 2004, 2006 and 2007, it shows a significant increment. Surface and groundwater [26] contamination with coliform can be attributed to the surface runoff through urban areas and meadow, disposal of sewage and so on [20]- [24]. Therefore, a significant upward trend for coliform at Perlis River at the year 2003, 2004, 2006 and 2007 is possibly due to the domestic waste or municipal sewage which discharged by the residents at the urban areas such as Kangar.…”

Trend detection of hydrologic da a is useful in the investigation of water quality parameters. In this study, thirty physicalchemical variables on water quality of Perlis River Basin were collected by Department of Environment (DOE) Malaysia from 2003 to 2007 were analyzed using the non-parametric Mann-Kendall Temporal test. Based on this study, the results acknowledged parameter variation over station due to the increasing of Cr concentration and reduction of COD along Perlis River Basin. Correlation coefficients were calculated to identify the strength of the linear relationship between two variables and this unveiled that DS and SS have the strongest correlation.
