USE OF MATHEMATICAL MODEL AS A TOOL FOR IMPROVEMENT OF DRAINAGE CONGESTION OF A RIVER SYSTEM: CASE STUDY MRIGI RIVER DRAINAGE IMPROVEMENT PROJECT IN BANGLADESH

摘要

Drainage congestion in the river system due to siltation is one of the major problem in Bangladesh. A one-dimensional mathematical model is applied to simulate the variations in water level and discharge with and without project in the Mrigi River Drainage Improvement project. The results show the potential of computer-based simulation model for assessment of the hydraulic behaviour of the river system. The model will also simulate the performance of the system giving input data like topography, boundary conditions etc. Such a mathematical simulation model constitutes a useful computational tool for the development, assessment, control and utilization of water resources.
