Sediment transport modelling: effect of the coastal reservoirs development plan in the Cisadane estuary-Indonesia
National Capital Integrated Coastal Development (NCICD) aims to protect Jakarta from flooding. This project includes a coastal reservoir (CR) development plan at the Cisadane Estuary, Tangerang Regency, Indonesia. CR planning must consider the sedimentation process. With numerical modelling of sediment transport, the sedimentation pattern of bed load and suspended load sediments will be known. This study used the MIKE21/3 Integrated Models software that is coupled with Flow Model (FM) and Mud Transport (MT) for one year (August 1, 2020 - July 31, 2021). The validation result of surface elevation shows that the modelling results are valid with NRMSD 93.35%. Based on the simulation results, suspended sediment concentration in the west monsoon is higher than in the east. The sediment concentration around the coastal reservoir at the bottom layer of the water is slightly higher than the surface layer. There is an increase in the maximum bed thickness of 1.2 m in the northeast corner of CR. There is a reduction in the bottom thickness of about 0.5 m on the west side of the CR embankment. The results of this study can be used to develop the most optimal CR design to minimise the environmental impacts.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
