Abstract:
The daily flow of Kampar River’s and the mining of it’s materials predicted will affect on the bed form changing and distribute the bed loads (errotion). The bed load transportation will affect on bed form stabilities, and the trend of bed form configuration. Because of that, this research will examine the trend of bed form configuration caused of daily flow and the exploitation of materials. The recording of rivers velocity, the depth and the width of rivers are used to define Kampar Rivers flow. The rivers velocity rate is also used to define the earlier particles movement. The sample of materials were taken at the same location when the rivers velocity were recorded. Sieve analysis and bulk density of materials are used to describe it’s gradation, earlier material movement, and bedform configuration on the rivers. Based on the result of it’s research, it can be concluded that the bad materials of Kampar Rivers have ununiform distribution and it’s material classified to very fine gravel up to very coarse gravel according AGU classification. A long of the research’s location at Kampar Rivers, the sedimentation, errotion, and sediment transportation are occurred on several segments as the effect of flow velocity and dry stress. A bedform trend a long Rantau Berangin – Bangkinang City segments show the planed bed, dunes and standing waves phases. It can be concluded that daily flow and the exploitation of materials are affect the material variation.
