The Effect of Precipitation on Sediment Transport at Batang Padang River, Perak

Abstract:

Study of sediment management is important to ensure the sedimentation process that occurred can be properly managed. Sediment have a positive correlation with the precipitation where, if the amount of precipitation is high then the sediment transport rate also will be increase. The additional of sediment into the river will shallow the river and lead to flooding. Thus, this analysis is carried out on the Batang Padang River to prove that there is a positive reaction by the precipitation and the amount of sediment, and will affect river management. The precipitation and sediment data from 1982 to 1996 were retrieved from Department of Irrigation and Drainage (DID) data base. Statistical analysis using the methods of correlation was used to determine the relationship between two variable has been prescribed. Based on the analyzed data, the highest value of rainfall was 3832.5 mm in 1988, and the highest value of sediment is 15331.9 tonnes/year was accured in 1985. Grade correlation is between 0:51 to 0.94 for observations fifteen years. Where the average grade of correlation that has been analyzed is 0.7. The results of the data analysis clearly shows that precipitation has a significant relationship with sediment.
