Sediment Transport Modelling with Advanced Hydroinformatic Tool Case study - Modelling On Bega Channel Sector

摘要

Understanding of sediment transports related phenomena's (soil erosion, particles entrainment, transport and deposition) is important for predicting sediment and contaminant transport in surface water networks. Sediment transport is a critical process in many environmental and hydrotechnical systems, due to its negative effects (eutrophication and siltation of reservoirs, water courses, channels and harbours, earth dam's failures, decreasing of reservoirs storage capacity, damage and loss of wildlife habitat, flooding, especially flash flooding, damage to public health, increase costs of water treatment for drinking, decreased fertility of agricultural land etc.). The management of most aquatic ecosystems and hydrotechnical arrangements requires a detailed understanding of sediment dynamics, with their environmental and economic implications, especially where there is any anthropogenic involvement. Numerical simulations of sediment transport with advanced hydroinformatic tools are often the most efficient and practical methods for predicting sediment transport in complex hydrotechnical systems. Numerical modelling requires descriptions of the individual processes involved in sediment transport: erosion, entrainment, movement of sediments and deposition in the water column. This paper analyzes the necessity and possibility of sediment transport modelling with advanced hydroinformatic tool.
