ClearTrajectory of microplastic particles with 2-dimensional hydrodynamic modelling approach at Pekalongan waters, Central Java, Indonesia
Researchers used two-dimensional hydrodynamic modeling to track how microplastic particles move through the waters near Pekalongan, Central Java, Indonesia. They found that tidal currents and seasonal monsoon patterns significantly influence microplastic transport and accumulation near fishing grounds. The study provides a tool for predicting microplastic hotspots that could help guide marine debris management in the region.
Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
Researchers measured microplastic concentrations in water and sediment at the mouth of the Sengkarang River in Indonesia and built a hydrodynamic model to track how tidal currents, wind, and river flow distribute the particles. Microplastics were highest in coastal waters and mangrove sediments, with tides and currents driving horizontal transport and concentrating particles in biologically sensitive habitats. The modeling approach offers a practical framework for predicting where microplastics accumulate and informing pollution management in river-to-sea systems.
Estimation of bottom microplastic flux in the Indonesian seas
Using ocean circulation models and Lagrangian particle tracking, researchers estimated microplastic flux to the seafloor from 68 Indonesian rivers, finding that accumulation concentrates within 50-100 km of major islands. The Karimata Strait, Java Sea, and South Java were identified as the primary accumulation zones within Indonesia's Fisheries Management Areas.
Marine macro debris transport based on hydrodynamic model before and after reclamation in Jakarta Bay, Indonesia
This hydrodynamic modeling study predicted how marine debris would move in Jakarta Bay before and after planned land reclamation, finding that the new island configuration would alter debris transport patterns. The study is relevant to understanding how coastal development affects the distribution of plastic waste.
Spatial Distribution and Quantification of Microplastic Contamination in Sediments of Kaliratu Coastal Waters, Kebumen, Indonesia
Researchers found microplastics in sediments along Kaliratu Beach in Indonesia at concentrations of 25–57.5 particles/kg, with fibres, fragments, films, and pellets all present, and used hydrodynamic modelling to trace how seasonal monsoon currents distribute them along the coastline. The findings highlight that even relatively remote Indonesian coastal areas near shrimp ponds and other anthropogenic activity are accumulating measurable plastic pollution.
Impacts of wind forcing on microplastics kinematic in a sensitive water area
Researchers modeled how wind forcing affects the movement and distribution of microplastics in a sensitive coastal water area, finding that wind-driven surface currents are a dominant control on where microplastics accumulate. The model predicts substantial wind-driven concentration at specific coastal zones.

Microplastics distribution on the beach sediment based on satellite remote sensing: A case study in Bali, Indonesia
Researchers examined how seasonal ocean currents and tourism activity influence microplastic distribution across three beaches in Bali, Indonesia, between January and July 2024. The study integrated polymer-level characterization with site-specific hydrodynamic data and satellite remote sensing to map microplastic accumulation patterns in beach sediments.

Researchers developed a hydrodynamic model to track the drift and accumulation of microplastics in the Baltic Sea, linking coastal emission sources to offshore accumulation zones and identifying key oceanographic processes that govern the fate of land-derived plastic pollution.
Using hydrodynamic models to understand the impacts and risks of plastic pollution
This paper used hydrodynamic computer models to simulate the transport and accumulation of plastic pollution in estuarine and coastal environments. The approach helps predict where marine litter concentrates based on currents and geography, which is useful for targeting cleanup efforts and informing coastal management policies.
Physical Control on Marine Debris Spreading around Muara Gembong, Jakarta Bay
Researchers used numerical modelling combined with artificial debris pathway analysis to investigate how marine debris from the Citarum River disperses around Muara Gembong in Jakarta Bay, finding that debris trajectory patterns differ substantially between the northwest and southeast monsoon seasons due to varying ocean currents, tides, and wind patterns.
Microplastic Distribution in Beach Sediments: Comparison Between the North and South Waters of East Java Island, Indonesia
Researchers compared microplastic concentrations in beach sediments on the north (Java Sea) versus south (Indian Ocean) sides of eastern Java Island, Indonesia, finding higher levels on the northern beaches that are closer to major population centers and shipping lanes. Fiber shapes and blue color dominated across all sites, and concentrations ranged from about 55 to 103 particles per kilogram. The study highlights how local population density, coastal morphology, and ocean current patterns together shape where microplastics accumulate on tropical beaches.

This study tracked monthly variations in marine debris discharged from the Greater Jakarta area in Indonesia, identifying land-based sources including rivers and coastal communities as major contributors. Peak discharge events correlated with rainfall patterns, highlighting the importance of monsoon-season waste management in reducing ocean plastic pollution.
