... subenvironments is still unclear. This paper documents the internal architecture of a digitate delta based on the integration of shallow-core and ground-penetrating radar data from the Ganjiang Delta, China, coupled with Delft3D simulations. Our results show that multiple convex-up muddy-silty accretion beds...

... energy thereby reducing sediment transport. The Delft3D hydrodynamic model is used to simulate waves, currents, and sediment transport in seven sea ice concentration scenarios that can be differentiated into four classes: open water (<10%), low ice (10% to 35%), moderate ice (36% to 60%), and high ice...

...Figure 2. A–C: Serial maps of Delft3D (oss.deltares.nl/web/delft3d) simulation with relative sea level (RSL) fall of 3 mm yr −1 showing initial condition (A) and two subsequent delta lobe avulsions (B, C). Elevations seaward of delta shoreline are clipped. Thick, smooth black lines indicate...

... simulations (Delft3D) are used to investigate the influence of tidal currents on deltas. Tidal amplitude and the sand:mud ratio of subsurface sediment have been varied in the model. The results show that increasing tidal amplitude causes deeper and more stable distributary channels and more rugose planform...

...Fig. 3.— Predictions of various delta metrics from Delft3D. A) Number of active distributaries increases with increasing proportion of sand delivered to the delta. The number of distributaries also increases with decreasing cohesion, except for mud-dominated deltas. B) Rugosity values...

..., 1994 ). To explore why lower specific discharges lead to floodplain channelization, we used numerical modeling experiments to simulate headcut development on low-gradient floodplains. We performed a series of numerical modeling experiments in Delft3D ( https://oss.deltares.nl/web/delft3d/home...

... and Tracadie bights, both of which are sand-rich onshore and sand-starved between 20 and 50 m water depth. Storm winds and waves from the northwest and northeast are common in autumn and winter. The hydrodynamic model Delft3D is used to simulate waves, currents, water levels, and sediment transport in Brackley...

... synthetic deltas are generated with the open source process-based software Delft3D ( Lesser et al., 2004 ; Roelvink and Van Banning, 1995 ), using the web-based modeling system Delft3D-GeoTool ( Storms et al., 2016 ). For our case study, we simulated sediment deposition in a shallow marine setting, where...

... characteristics of tidal bedding and quantify their extent in mouth bars. Findings from our analytical model are compared with results from the numerical model Delft3D. From landward to seaward and in the absence of tides, our analysis shows that a sand-dominated zone is followed by a depositional environment...
