Preliminary study on the impact of flow rate and sediment load to the geometry formation of meanders in a meandering river / Noor Safwan Muhamad, Junaidah Ariffin and Zulhafizal Othman

This study demonstrates the development of meanders with respect to different flow rate and sediment load
The knowledge on meanders is important. not only because it changes the geometry of the river but it also
can cause threats to the people and properties. With more than 150 rivers throughout Malaysia. the
knowledge on meander behavior is vital to avoid problems associated with poor planning of the development
at riverside. Eight sets of experiments have been conducted using Armfield S12 MKll Advanced Hydrology
Study System at the Faculty of Engineering. UNISEL Bestari Jaya Campus. The experiments was conducted
under controlled environment with flow rate and sediment load as the variable parameters while the other
factors that can affect meander growth and migration are kept constant. The changes in cross section were
measured and 3D surface was generated using Surfer 9 to analyze the effect of variation in flow rate and
sediment load to the erosion. transportation and deposition processes that involved in meander meander
growth and migration. The relationship between flow rate and sediment load with the migration and growth
pattern of meanders are discussed well in this paper. This study is meant to be continued further to come out
with suitable equations in predicting meander migration
