Abstract
River meandering is a net outcome of erosion and deposition It initiates and develops width adjustment and planform evolution. Meandering process involves adjustment of the planimetric geometry and hydraulic factors. Many structures built within the vicinity of the river such as bridges, waterways/navigation and flood control contraptions are affected by river meandering and its distance. This research was carried out on a physical river channel model measuring 10m long, 2.4m wide and 1.8m deep located at Universiti Teknologi MARA Puncak Alam. Correlation analysis between the lateral migration rate, M and mean velocity, Umean to other variables. According to the physical consideration on lateral migration rate, M, there are three (3) major categories affecting channel bankline migration. There are hydraulic characteristics, water properties and soil properties, of which the latter is resistance to erosion. Therefore, the objective of this paper is to investigate the factors governing lateral migration rate for the development of an empirical model to predict lateral migration rate under the influence of non-migrating mid-bar.
