| Outline of Final Research Achievements |
In this study, field survey of river and estuarine morphology were conducted in order to investigate demonstratively the relationship between dissipation, formation and development processes of mouth-bar and sediment transport in downstream region of river. A new practical simplified Lagrangian bedload model was developed in order to improve the accuracy of simulation results of estuarine morphology processes. The new bedload model was introduced into depth-averaged flow model with bed variation model and applied to an actual river. The new model was compared with previous general Euler type bedload model and data of our field measurements, and it was indicated that the new model reproduced well especially in meandering reach.
