The effect of flow and sediment matrix to the formation of mid-channel bar in river / Mohd Zulkhairi Mat Salleh

Mid-channel bar is one of the issues that are found in river. It contributes to flood occurrence along flood plain. The formation of mid-channel bars is related to various factors such as flow, sediment, vegetation and others. Previous researchers had carried out many studies but the understanding o...
